It is invigorating. Have you looked at Her yet? Tonight i am grateful that i am able to meet, communicate and help people through my job. Tonight i am thankful that i can be Her daughter and feel Her guidance and protection. Tonight i am glad that i have a life full of people who love me and that i love. Tonight i am happy for being a witch.
Tonight is a wonderful time to be a witch. It is a time for witches to dance and celebrate. To draw down the Moon and glow in Her glory. To control their energy so that they can heal themselves and others. To protect and be protected. To gain the things we need. To achieve our goals.
I am wishing you all a Happy Esbat and a beautiful night.
Blessed full moon.

Tonight i am happy for being a witch.
New moon.
A beautiful night awaits us blogfriends. Tonight we will celebrate the new moon. A perfect opportunity to connect with our Mother. A time to blow two kisses to the Moon so She can bring us good luck. A time to heal and grow.
We should take this opportunity to come in touch with our darkest aspects, acknowledge them and heal. We can get rid of bad thoughts, feelings, habits and energies. We burn black candles to do that, but since it is Moon magic we also burn silver, white and grey ones. It can be something as simple as my goal(to eliminate the usage of aspartame, i eat massive amounts of that horrible thing) or as complicated as depression. We acknowledge the thing that bothers us and take the power from our Mother to get rid of it. We can burn herbs associated with Moon(jasmine,willow,eucalyptus, ivy, lemon balm, poppy, myrrh,mugwort) or bath in them, since Moon rules the Waters. We can also use them to make sachets.
I, myself, no longer need aspartame in my life. The last time i tried to do that i have put my hopes up for stevia. When i took home this really expensive natural sweetener i found out it has a horrible taste that urges you to scrub your mouth with soap and chlorine! I gave up too easy. But today i was ready to try again. So in my coffee i put half a teaspoon of sugar. It was bitter at first but now i am starting to get used to it. I am also ready to use other natural sweeteners as agave nectar. I can not get it completely out of my life, since they put that thing in everything(even my vitamin C supplements have aspartame) but i will not use it in cooking, coffee and of course i won't drink the litres per day of diet coke i used to drink. A while ago this felt like such a huge step. But this powerful new moon made it easy for me. Let Her make your goals easy as well.
I will keep you update with my progress. I am wishing good luck to all of you. Have a happy new moon.
Brightest blessings,
Lets make happier streets...
Greetings blogfriends. In the past i have spoken about the Law of Attraction. Whatever you might call it, we all try to stay positive even in the most difficult or disturbing of situations. We try to get rid of the negativity and exchange all bad thoughts with new good ones. And although sometimes we do not succeed the whole effort is rewarding for both our mental and physical health.
So, we try to remain calm, happy, forgiving etc. and in the meanwhile a bad driver on the street almost kills us and all our calm, happy, forgiving thoughts go out of the window. We swear, we give him the finger, and generally we feel bad feelings and think bad thoughts. This happened to me today( i am sure i am not the only one) all accidents were avoided so i would normally forget all about it before i got home. But when this happened to me, while i put my eyebrows together trying to be creative on my namecalling, i exhaled and said:"Be careful and good luck". It made feel so wonderful. So, naturally, i took the decision to always do that. I considered the fact that someone could call me names on the street. Well, in that case, i thought i would say it outloud and let him think i am certifible. I do not know in your country how this goes, but in Greece, even the people who are at fault swear on the street. It is a crazy world and i intend to make it even crazier.
I ask of you to follow me on this path of madness to wish luck to those that scare us while we are driving. A small change that could possibly brighten up our days. I can not yet take it to the next step and do it everywhere with everybody. I am not the "turn the other cheek" kind of gal. How about you? Do you have any small tips to use the Law of Attraction in our favors?
love and light to all of you,

Michigan voters are being asked to support a 25 percent renewable energy standard and lock that standard into the State Constitution on ballot Proposal 3. The ballot language in this 277 word proposal might be viewed harmless and one might even consider voting for this proposal if you didn't know that Michigan lawmakers passed an energy law in 2008 requiring a 10 percent renewable energy standard by 2015 and once that 10 percent goal is reached in 2015, it will be reviewed again by our lawmakers to ensure that Michigan continues on an affordable path to clean energy.
This ballot proposal also does not account for the 12 billion dollars that would be required to meet this standard, at a time when our State and our local communities continue to recover economically. Energy suppliers would be required to invest in technology that will likely change in the ensuing 13 years and Michigan families and businesses would be forced to spend this money on today's technology. Reaching a 25 percent renewable standard would require as many as 3,100 additional wind turbines and result in the uncertainty of local control where these turbines will be located. This would dramatically change the face of our State and our local communities.
Our State Constitution is not the place for energy policy. No other State in the country has mandated in their State Constitution an energy portfolio standard. Proposal 3 would lock a reckless renewable energy mandate into our State Constitution and eliminate the flexibility needed to deal with changing customer needs, emerging technology and to provide our families and businesses with cleaner, affordable, reliable electric service.
Michigan is already on a smart, affordable path to a greener energy future. I encourage you to oppose this '25 x 25' mandate and vote "no" on Proposal 3.
– Barbara Mitzel

The tables below list all tuition fees for new students in the 2018–2019 academic session. Please note that fees are charged by year of entry to the College and not year of study. To find your fee, please select your research field and then check the fee for your year of entry.
The UK Research Councils (RCUK) have now confirmed their indicative fee for 2018-19 and this fee increases annually by an amount linked to inflation (currently, the measure used is the GDP deflator); fees for subsequent years of study may be higher than the fees listed here. All fees shown in italics are provisional pending the release of the RCUK indicative fee in the Spring of 2018. Imperial College London reserves the right to amend these fees following the release of the indicative fee by the RCUK. For more information on the Research Council Indicative Fee please see the RCUK website.
Students undertaking research on a part-time basis will be charged half the relevant full-time fee.

If you or someone you know are interested in participating in a future clinical research study for Coronavirus/COVID-19, please fill out the form below and a member of our team will be in touch with you in the next couple of days.
When you participate in a clinical research study, you become an agent of change. Research participants are critical in helping physicians and other researchers develop and test better ways to diagnose and treat patients. Your participation helps move science forward, helping to develop new therapies for chronically and critically ill patients. You can read more about how a covid-19 vaccine study would work in this article by the Cincinnati Business Courier.
Additionally, as a participant in a study, you may be eligible to receive compensation for time and travel.
Once you let us know you or someone you care for are interested in becoming a part of a clinical research study, a member of our team will be in touch soon. That team member will ask you for some additional information to help us place you in the correct study.
After that, all you have to do is wait! We will email or call you when we have a study that you may qualify to participate in. Keep in mind that every study is different because each study is researching a different indication. So, just because we call you may not mean you qualify to enroll in that study. However, we always have more studies rolling in, so there will always be more opportunities for you to help.
If you have any questions, please don't hesitate to call us at (513) 721-3868. We look forward to hearing from you!

Fire Ants, those scorching stinging insects, have a strange attraction to technology but no one really knows why. From tearing up wires and creating short circuits, fire ants just love to destroy technology. Watch them in action in this video from BBC Earth.
Even more amazing, the fire ants can avoid getting zapped by the microwave. The ants can sense where the waves are being sent and move around to avoid it. Clever little buggers they are. [BBC Earth via Neatorama]

I'm trying to find out a bit more about the data security of Trello as I'm trying to introduce the use Trello at the company I work for.
The company is ISO 27001 accredited and is therefore hesitant to use any cloud based services. We have to put any new technology past our security review boards so can someone advise on the actual data security, i.e. is the database / backup aspects rather than the traffic which I know is SSL.

The most important traffic regulations and other helpful details about law in Italy.
Watch out on South Tyrol's roads.
Since 2003 a new traffic code is in force on Italy's roads.
Exceeding the speed limit is punished with heavy fines: Exceeding the limit by 10 km/h with a fine of € 100 and more; by 40 km/h and more the driving license is withdrawn for several months.
Find below other useful information for your holidays in Italy:
1. Since 2004 warning vests are obligatory - you must carry it always with you in the car to have the possibility to show it or to use it in emergency cases.
2. You must use dipped headlights during the day while travelling on motorways and major roads outside cities.
3. Watch out: On the Brennero Motorway (A22) between Brennero and Bolzano Sud, the maximum speed is limited to 110 km/h - not to 130 km/h as usual on Italian motorways.
4. Always give way to pedestrians crossing the crossways. Otherwise you face high fines!
5. Drunken pedestrians who are yelling loud in the streets will pay for it.
More useful information:
1. An official ban on smoking in all enclosed public places has come into force in Italy on July 1, 2005. Fines may amount up to € 2,000. Few bars are not subject to the ban but are required to have designated smoking areas, which must be sealed off from the rest of the premises and fulfill strict criteria.
2. Bying faked brand products is punished with heavy fines.
3. Smoking cannabis is punished with the withdrawal of the driving licence or other valid papers; a charge is pressed.

winners & links
(image credit Mikkel Mortensen)
Sorry for the silence on my end! I am here and alive, I promise. Keeping up with the baby and Israel and shop things take up every second of the day so by the time I get to bed, exhausted physically and emotionally I lay there thinking about my poor neglected blog and how I need to multiply myself somehow. Certainly I don't want the blog to be a place where I just whine and complain about things because that's not fair to you and I'm not a whiny person anyways. At the same time if I can't be honest on my own blog, where can I be?!
Ok, now to move on to announcing some of the winners of the giveaways I've been hosting. I think that was a solid month of giveaways wasn't it? Aaaaaand I still have one more. It's another good one, this time from Aussie store The Minimalist.
The winner of the Kristina Krogh notebooks is Tara Victoria
The winner of the Nest.co.uk Muuto leaf lamp is Maija
Please contact me here with address information.
To make up for my lack this week here are some links worth checking out:
new Ikea PS 2014 collection looks great
last day of the Instagram #stylingteammichigan (I contributed a few) that was started by Lotta Agaton during her styling work in Michigan for Herman Miller. There have been some great contributions from different Instagrammers (is that a word?) so it's worth checking out.
Need Supply recently published a new lookbook shot entirely in/near their studio and it looks fab!
The new line from Mini Rodini is so fun and really makes me want for warmer weather. I can see my kids wearing all of it, such great prints
Slow Fashion House is my new favorite store!
This oval mirror is perfect.
Two videos, Maidentrip & My Beautiful Woman
I want to make these raw, vegan peanut butter cups.
This bright apartment deserves a double take.

Ok so I have to create a Java application that simulates a minimum of 3 spheres moving through a frictionless environment with gravity. The environment should be a confined cube area for the spheres to collide and respond. The application does need to display the positions of the spheres in real time, but the 3D vector positions should be saved for each sphere to an output file for future plotting. Set initial velocities and positions and run the simulation for at least 100 iterations. Design your application such that collisions and their associated responses will occur during the simulation.
I got the pseudocode for this I think but I cant get it into java code for the life of me.
I get most of it but I cant seam to get it into code.void main() { //variables needed by the sim Vector3D cur_S[2*N]; //S(t+delta_t) Vector3D prior_S[2*N]; Vector3D S_derivs[2*N]; float mass[N]; float t; float delta_t; //set current state to initail conditions for(i = 0; i < N; i++){ mass[i] = mass of particle i; cur_S[2*i] = particle i initial linear momentum; sur_S[2*i+1] = particle i initial position; } while (game simulation is running){ DoPhysicisSimulationStep(delta_t); for (i = 0; i < M; i ++){ Render particle i at postion cur_S[2*i +1]; } } //update physics void DoPhysicisSimulationStep(delta_t){ copy cur_S to prior_s //calculate the stae derivative vector for(i = 0; i < N; i++){ S_derivs[2*i] = CalcForce(i); S_derivs[2*i+1] = prior_S[2*i] / mass[i]; } //integrate the equations of motion ExplicitEuler(2*N, cur_S, prior_S, S_derivs, delta_t); t = t+ delta_t; } }

I was actually in the weight room doing my work and John Farrell had come in and said, "Tito wants to see you after he talks to the other guys." I didn't know what other guys. Then I got to his office and the office was closed. When it opened, he called me into the office and I saw all the other guys walking out with their All-Star packages. He sat me down and tried to play it off like it wasn't good news. He couldn't hold the laughter.At 42 years old, Wakefield is the oldest All-Star rookie since Satchel Paige went to the 1952 ASG at age 46. Jamie Moyer (40 in 2003) and Connie Marrero (40 in 1951) are the only other players to become All-Stars for the first time at age 40+.
I feel very honored and humbled at the same time. Excited and nervous. I have a lot of emotions going through me right now. ... I've been asking guys that have been there what to expect, how to dress and how to act -- things like that. It's been a fun day asking a lot of questions, that's for sure.Amalie Benjamin had a lengthy feature on Wakefield in Sunday's Globe.

Resolved Caveats for Release 6.2
New Features and Functionality
Obtaining Documentation and Submitting a Service Request
Changes to the Release Notes
This section documents supplemental changes that have been added to the Release Notes for Cisco ONS 15454 SDH Release 6.2 since the production of the Cisco ONS 15454 SDH System Software CD for Release 6.2.
The following changes have been added to the release notes for Release 6.2.
Changes to New Features and Functionality
The subsection for new DWDM SFPs has been removed. These SFPs will be supported in a future release.
Review the notes listed below before deploying the ONS 15454 SDH. Caveats with DDTS tracking numbers are known system limitations that are scheduled to be addressed in a subsequent release. Caveats without DDTS tracking numbers are provided to point out procedural or situational considerations when deploying the product.
STM1E-12 Card Support
The STM1E-12 card is not supported in this release. This card will be supported in a future release. Caveats herein pertaining to this card also do not apply.
Rarely, the non-enhanced Muxponder unit does not pass Jitter Tolerance test from Trunk port to client port as per ITU-T G.825, 2 Mb/s mask, at the 10 Hz specific setpoint. The Muxponder should be configured with G.709 Off, FEC Off and Trunk signal provided by external Jitter test box, and the unit client port output monitored for errors, to see this issue. This issue will be resolved in a future release. Note, however, that in normal network configurations the muxponder is operated with G.709 and FEC turned on, and the jitter tolerance tests pass.
Under specific conditions the non-enhanced MXPD does not pass the Telcordia GR-253/G.825 Jitter generation mask test on 10G TX Trunk port. The 2.5 G TX Client jitter generation is always within mask and does not exhibit this issue. This occurs only when, in SONET mode, there is no FEC, no G.709, and client interfaces are looped back, with non-synchronous clocking, and the jitter testbox TX connected to Trunk RX port, while the jitter testbox RX is connected to the Trunk TX port. The jitter testbox TX clock recovers from RX with an additional 5 ppm offset added. This issue will be resolved in a future hardware release.
The TXP_MR_2.5G and TXPP_MR_2.5G cards do not support TX Optical power performance monitoring on the trunk port. To see this, go to the Optics Performance Monitoring tab of the TXP_MR_2.5G or TXPP_MR_2.5G card, and select the trunk port. TX Optical Pwr is not shown. This is as designed.
SDH DS3-I and E3 electrical cards only support a VC4 J1 trace string setting for all VC4s together. You cannot set the J1 byte for individual VC4s. This issue is a limitation of hardware.
Note VC3 J1 strings can be set individually, but the optical cards cannot monitor the VC3 J1 string.
Interconnection Equipment failure alarms may be generated at 55 degrees C, and 72 volts. When the operating environment is at 55 degrees C and 72 volts, interconnection equipment failure alarms for the following cards can occur:
The alarms could potentially occur on any of these boards, as well: OC48AS, GigE, OC192 or OC192LR. This issue will not be resolved.
E1-14 boards with second source components can incur bit errors under extreme environmental conditions. When these boards operate under voltage and temperature stress conditions and a temperature ramp rate of 1 degree per minute, the boards could exhibit dribbling bit errors at high temperatures: BER = 5.5e-6. To avoid this, you must apply the temperature ramp rate at 0.5 degree per minute. This ramp rate complies with the NEBS standard; however, this issue will be revisited in a future release.
CSCec42769 Database Corruption with ONS 15454 SDH Release 4.0, 4.0.1, 4.1
Caution Before you upgrade to Release 6.x from Release 4.0, 4.0.1, or 4.1, you must read this caveat and run the SDH Circuit Repair Utility (VcCheck) provided on the software CD (also available on CCO).
The XCVXL card on the ONS 15454 SDH allows the intermixing of VC12 and VC3 payloads within a single VC4. When a VC4 contains only one VC12 tributary and at least one VC3 tributary and the VC12 is deleted, the database becomes corrupt.
The database load process on the ONS 15454 SDH occurs during a TCC2/TCC2P reboot, TCC2/TCC2P protection switch, software activation, or database restore. When the database is loaded containing this corruption the load process fails, causing the corrupt database to be deleted from the TCC2/TCC2P flash memory. The previous saved database is then loaded instead. When all saved databases on a TCC2/TCC2P contain the corruption, the TCC2/TCC2P will load with the default provisioning, and all existing provisioning will be lost.
If this issue occurs you will see a loss of either some or all provisioning after a TCC2/TCC2P switch or reset.
To ensure that your network is not vulnerable to this issue, you must first determine if the issue already exists within your network, and if so, correct it. You can detect the issue by using the SDH Circuit Repair Utility (VcCheck) provided on the ONS 15454 SDH Release 4.1.3, 4.6.x, 5.x or 6.x software CDs. The VcCheck tool is also available for download from CCO. Once you have alleviated immediate risk from the issue, you must upgrade to Release 6.x, Release 5.x, Release 4.6.1, or maintenance Release 4.1.3 (or any later release) to avoid further risk.
The VcCheck utility and its associated README file (in the same directory with the tool) provide details on how to temporarily alleviate this issue before upgrading to a release in which the issue is resolved.
This issue is resolved in Releases 4.6 and later, and in maintenance Releases 4.1.3 and later (caveated herein because of the upgrade issue).
Maintenance and Administration
Caution VxWorks is intended for qualified Cisco personnel only. Customer use of VxWorks is not recommended, nor is it supported by Cisco's Technical Assistance Center. Inappropriate use of VxWorks commands can have a negative and service affecting impact on your network. Please consult the troubleshooting guide for your release and platform for appropriate troubleshooting procedures. To exit without logging in, enter a Control-D (hold down the Control and D keys at the same time) at the Username prompt. To exit after logging in, type "logout" at the VxWorks shell prompt.
Note In releases prior to 4.6 you could independently set proxy server gateway settings; however, with Release 4.6.x and forward, this is no longer the case. To retain the integrity of existing network configurations, settings made in a pre-4.6 release are not changed on an upgrade to Release 6.x. Current settings are displayed in CTC (whether they were inherited from an upgrade, or they were set using the current GUI).
When you upgrade from Release 6.2 to 7.0 CTC displays a popup window asking if you want to delay the ML-series card portion of the upgrade. This is the ML-series Version Up feature supported in Release 6.2. This feature is not supported in Release 7.0; and so, if you select the Version Up option, you should not expect the ML-Series upgrade delay to actually occur for Release 7.0. The display of the popup window in this case is an error. This issue only occurs when upgrading from a release that supports Version Up to one that does not, and will be resolved in a future release.
Rarely, autoprovisioned audits (those with the unique ID of 0) can become stranded after a bulk roll of VC LO circuits prior to deletion of those circuits. If an attempt was made previously to delete all such circuits, you can use subtractive logic to discover which circuits have become stranded. That is, matrices indicating usage in the node view, Maintenance > Cross-connect > Resource Usage window will indicate stranded circuits.
Once you have identified that there are stuck STSs, go to the card view for each affected trunk card and view the Maintenance > Loopback > SDH STS tabs. From here you can view all used STSs, including any stuck STSs. Determine which STSs in your network have no circuit associated with them, then create and subsequently delete a LO circuit on each affected STS. This will clean up the stuck STSs. This issue is resolved in Release 7.0.
A CTC client session can disconnect from an ONS node during simultaneous deletion of large numbers of VT level circuits (3000+). Connectivity to the node will recover without any user action. If the condition persists, restart the CTC session to reconnect. This issue is under investigation.
When one of the underlying connections of a circuit moves to the Unlocked-disabled, failed state, CTC treats the Unlocked-disabled, failed state as out of service and interprets part of the circuit to be out of service, or Locked. However, this is incorrect, as none of the underlying connections is in a Locked state. The result is that the circuit state is displayed as Locked[Partial], even though all of the underlying connections are technically Unlocked. This issue is resolved in Release 8.0.
A signal degrade or signal failure is not reported when you inject bit errors into the line for an E3 card. To see the SD or SF, inject a code violation error instead. This issue will not be resolved.
When you create a bidirectional MS-SPRing-SNCP IDRI circuit using autorouting and select the PCA option for secondary spans, the circuit is created over working MS-SPRing spans and does not use PCA spans. To enforce the use of the PCA option, provision the circuit using manual routing. This issue will not be resolved.
Sometimes, in a 1:N protection group, a locked-out working card carries traffic. This issue can occur when you lock out a working card, reseat that card, reseat the protect card, and then, while the protect card is booting up, remove another working card. After the protect card comes up, it starts protecting the traffic for the removed card and the locked-out working card carries its own traffic. This issue is resolved Release 7.0.
A traffic hit can occur during a clock reference switch. To see this issue, complete the following steps.
Step 1 Set up two ONS 15454 SDH nodes with STM16 SNCP (call the nodes STM16-1 and STM16-2).
Step 2 Set up two ONS 15454 SDH nodes with MXP_MR_2.5G_10G (call the nodes MXP-1 and MXP-2).
Step 3 Place MXP-1 and MXP-2 in Transparent Termination Mode.
Step 4 Ensure that STM16-1 is connected to MXP-1 client 1.
Step 5 Ensure that STM16-2 is connected to MXP-2 client 1.
Step 6 Ensure that MXP-1 trunk is connected to MXP-2 trunk.
Step 7 Connect a traffic generator to MXP_MR_2.5G_10G Port 3 (client) of MXP-1 and feed a PRC clock.
Step 8 Set MXP-1 Clock Reference 1 to MXP_MR_2.5G_10G Port 3, leaving the other two clock references as INTERNAL.
Step 9 Provision circuits such that a combination of VC4-4C, VC12, VC3 and VC4 traffic flows between STM16-1 and STM16-2 through MXP-1 and MXP-2.
Step 10 Gradually inject increasingly negative frequency offset through the traffic generator, in steps of 3 ppm, where you perform the next decrement step only when the node returns to NORMAL state.
When the clock offset reaches around 17 ppm, Clock Reference 1 fails and MXP-1 switches to Clock Reference 2. During the clock switch a traffic hit might occur for less than one second. The same is behavior can occur when injecting positive frequency offset. This issue will not be resolved.
The amplifier gain set point shown by CTC and the actual measured amplifier gain differ. The following steps illustrate this issue.
Step 1 Reduce the insertion loss of the span just before the amplifier.
Step 2 Execute the APC procedure.
The APC procedure does not check consistency between the gain set point and the real gain, but rather only verifies the amplifier total output power. As a workaround, manual setting can be performed to align these values, although the discrepancy does not impact the normal functioning of the amplifier. This issue will not be resolved.
In a fiber cut scenario on the LINE-RX, with OSC and channels provisioned, transient LOS-P or LOS-O alarms might be raised. This issue is resolved in Release 7.0.
The SQUELCHED condition is not raised when a non-enhanced MXP card is in MS termination mode. To see this issue perform the following steps.
Step 1 Set up one ONS 15454 SDH node with MXP_2.5G_10G (MXP-1).
Step 2 Provision MXP-1 Port 1 (client) with any payload.
Step 3 Set MXP-1 Port 1 (client) and Port 5 (trunk) to the UNLOCKED state.
LOS and LOS-P alarms are reported on MXP-1 Port 1 (client). The SQUELCHED condition is not reported on MXP-1 Port 1 (client) because AIS is sent out the client port instead. This is as designed.
Clearing the displayed statistics for a port will also clear the displayed history for that port. Clearing the displayed statistics for all ports will also clear the displayed history for all ports. There is no warning message from the TCC2. If History information is to be retained, do not clear displayed statistics for any port without first documenting the displayed history information for the associated port. This issue will not be resolved.
The ALS pulse recovery min value is 60 instead of 100. If this occurs, increase the value to 100. This issue will not be resolved.
In a Y-Cable configuration, if you remove the client standby RX fiber; a non-service affecting LOS is raised, as expected. However, if you then remove the trunk active RX fiber; a non-service affecting LOC is raised, but the previously non-service affecting LOS on the client port is now escalated to a service affecting alarm, in spite of no traffic having been affected. This issue will not be resolved.
After setting the node time (either manually or via NTP) you must wait for the endpoint of the interval to be reached before the end time will reflect the recently-set node time. Until this has occurred, the date time stamp for the end of the retrieved interval remains 12/31/69. This issue will not be resolved.
When changing NE timing from External or Mixed to Line timing, a Transient IEF alarm might be reported against the standby XC10G. This issue will be resolved in a future hardware release.
When replacing a failed working E1-42 card in a 1:1 or 1:N protection configuration with the protect card carrying the switched traffic, bit errors, less than 50ms in duration, are possible on the activated protection card. This issue will not be resolved.
CVs are not positively adjusted after exiting a UAS state. When a transition has been made from counting UAS, at least 10 seconds of non-SES must be counted to exit UAS. This issue will not be resolved.
CTC is unable to communicate with an ONS 15454 SDH that is connected via an Ethernet craft port. CTC does, however, communicate over an SDCC link with an ONS 15454 SDH that is Ethernet connected, yielding a slow connection. This situation occurs when multiple nodes are on a single Ethernet segment and the nodes have different values for any of the following features:
•Enable OSPF on the LAN
•Enable Firewall
•Craft Access Only
When any of these features are enabled, the proxy ARP service on the node is also disabled. The ONS 15454 SDH proxy ARP service assumes that all nodes are participating in the service.
This situation can also occur immediately after the aforementioned features are enabled. Other hosts on the Ethernet segment (for example, the subnet router) may retain incorrect ARP settings for the ONS 15454 SDHs.
To avoid this issue, all nodes on the same Ethernet segment must have the same values for Enable OSPF on the LAN, Enable Firewall, and Craft Access Only. If any of these values have changed recently, it may be necessary to allow connected hosts (such as the subnet router) to expire their ARP entries.
You can avoid waiting for the ARP entries to expire on their own by removing the SDCC links from the affected ONS 15454 SDH nodes. This will disconnect them for the purposes of the proxy ARP service and the nodes should become directly accessible over the Ethernet. Network settings on the nodes can then be provisioned as desired, after which the SDCC can be restored. This issue will not be resolved.
When the topology host is connected to multiple OSPF areas, but CTC is launched on a node that is connected to fewer areas, the topology host appears in CTC, and all nodes appear in the network view, but some nodes remain disconnected. This can occur when the CTC host does not have routing information to connect to the disconnected nodes. (This can happen, for example, if automatic host detection was used to connect the CTC workstation to the initial node.)
CTC will be able to contact the topology host to learn about all the nodes in all the OSPF areas, but will be unable to contact any nodes that are not in the OSPF areas used by the launch node. Therefore, some nodes will remain disconnected in the CTC network view.
To work around this issue, if no firewall enabled, then the network configuration of the CTC host can be changed to allow CTC to see all nodes in the network. The launch node must be on its own subnet to prevent network partitioning, and craft access must not be enabled. The CTC host must be provisioned with an address on the same subnet as the initial node (but this address must not conflict with any other node in the network), and with the default gateway of the initial node. CTC will now be able to contact all nodes in the network.
If a firewall is enabled on any node in the network, then CTC will be unable to contact nodes outside of the initial OSPF areas. This issue will not be resolved.
An LOP-P alarm can be inadvertently cleared by an LOS that is raised and cleared. On STM-N cards, when an LOP condition and an LOS condition are both present on the input, an LOS will be raised. However, upon clearing the LOS with the LOP still present, the LOP alarm is not raised. An AIS-P condition will be visible. This issue will not be resolved.
If a node has one good BITS reference and is running in a normal state, and you configure a second BITS reference, then reconfigure the second reference within 30 seconds of applying the first configuration, the node will enter FAST START SYNC mode. To avoid this problem, wait a minute before configuring the second reference a second time. This issue is a hardware limitation, and there are no current plans to resolve it.
Table 1 summarizes B1, B2, and B3 error count reporting for SDH optical cards. Note that not all reporting is done according to ITU specifications. In particular, ITU specifies error counts for B1 and B3 as the number of blocks with errors (refer to ITU-T G.826 for paths and ITU-T G.829 for RS and MS).

STM16 trunk
After creating 509 VLANs and provisioning many Ethernet circuits, Ethernet circuit provisioning can become very slow, or possibly fail. Ethernet traffic may also incur an outage of a few minutes. To avoid this problem, delete any VLANs that are created but not used, and do not recreate them. There is no resolution planned for this issue.
CSCdv10824: Netscape Plugins Directory
If you use CTC, JRE, and the Netscape browser with a Microsoft Windows platform, you must ensure that any new installation of Netscape uses the same Netscape directory as the previous installation did, if such an installation existed. If you install Netscape using a different path for the plugins directory, you will need to reinstall JRE so that it can detect the new directory.
"Are you sure" Prompts
Whenever a proposed change occurs, the "Are you sure" dialog box appears to warn the user that the action can change existing provisioning states or can cause traffic disruptions.
Common Control and Cross Connect Cards
Rarely, traffic hits can occur on TCC2/TCC2P card removal. To avoid this issue, remove the card quickly. To recover from this issue, soft reset the TCC2/TCC2P card. This issue will not be resolved; however, this does not occur when the newer optical line cards, TCC2P cards, and XC-VXC cards are used.
Ethernet Polarity Detection
The TCC2/TCC2P does not support Ethernet polarity detection. The TCC+ and TCCI both support this feature. If your Ethernet connection has the incorrect polarity (this can only occur with cables that have the receive wire pairs flipped), the TCC+/I will work, but the TCC2/TCC2P will not. In this event, a standing condition, "LAN Connection Polarity Reverse Detected" (COND-LAN-POL-REV), will be raised (a notification will appear on the LCD, and there will be an alarm raised). This issue will most likely be seen during an upgrade or initial node deployment. To correct the situation, ensure that your Ethernet cable has the correct mapping of the wire wrap pins. For Ethernet pin mappings, consult the user documentation.
Active Cross Connect or TCC2/TCC2P Card Removal
Active cross connect or TCC2/TCC2P cards should not be removed. If the active cross connect or TCC2/TCC2P card must be removed, to minimize network interruption you can first perform an XCVXL side switch and then remove the card once it is in standby, or you can perform a lockout on all circuits that originate from the node whose active cross connect or active TCC2/TCC2P will be removed (performing a lockout on all spans will also accomplish the same goal).
Caution If you mistakenly remove an active cross connect or TCC2/TCC2P card and you subsequently lose traffic on some interface cards, you may need to physically reset these cards if they fail to regain traffic.
Optical IO Cards
CSCee17695 and CSCed26246
Rarely, an STM1-8 card might fail to read MFG EEPROM and will show MEA in CTC. This issue can be reproduced by power cycling the node several times, by quickly removing and reinserting a fuse, or when the fuse is removed for several minutes and then replaced; however, the issue is not likely to be due to the power cycling. If a card enters this state, remove and reseat it, or cycle power again to recover STM1-8 operation. This issue will not be resolved.
Cisco ONS 15454 optical cards are not provisioned for particular path labels (C2 bytes). Consequently, they cannot raise a PLM condition. However, the ONS 15454 electrical card that terminates traffic ensures that the C2 byte is correct for the type of traffic carried. If the C2 byte is incorrect, this card raises a PLM condition that is reported against the optical port of ingress. An optical card will not raise a PLM against traffic that passes through a node, though it will appear to raise a PLM against traffic with the wrong C2 byte that is terminated on an electrical card within the node. This issue will not be resolved.
Note Optical cards do ensure that the C2 byte is nonzero (Equipped), and will raise a UNEQ condition if the C2 byte is 0 (Unequipped).
Electrical IO Cards
Long traffic hits can occur on E1-42 when using cross connect FIT cards. This can occur when, on the FIT card, you toggle the 155 mhz clock going to the E1-42 cards to the off position. This issue cannot be resolved.
Rarely, a long traffic hit (117 ms) can occur on E1-42 after an XC side switch. In multinode BLSR setups, switching the cross connect cards repeatedly might cause traffic hits greater that 60 ms. To avoid this issue side switch the XC only when needed (and not repeatedly). This issue will not be resolved.
Rarely, DS3I VC3 traffic takes a hit greater than 60 ms during a cross connect card soft reset. This issue will not be resolved; however, a node configured with the latest line cards, XC-VXC cards, and TCC2P cards, and with Release 6.0.x will not exhibit this behavior.
Bit errors can occur on E1-42 line cards passing traffic, when other E1-42 line cards are initially inserted into adjacent slots. Specifically, inserting line cards into adjacent slots or 1:N protect slots (Slots 3 and 15) can cause hits on Ports 1-14. Also, when the card in the 1:N protection slot is passing traffic, inserting E1-42 line cards into adjacent slots can cause bit errors. The bit errors characteristically last less than 5 ms. After the card is inserted, no further bit errors occur. Ports 15-42 behave differently. No bit errors occur on a line card residing in a non-1:N slot if adjacent line cards are inserted. Bit errors will only occur for these ports if line cards are inserted into the 1:N protection slots (Slots 3 and 15). Bit errors might also occur if traffic passes through the 1:N protected slot, and you insert a line card into any other working slot. A future version of E1-42 hardware will resolve this issue.
Interoperability with SONET DS3i-N-12
When provisioning circuits in SDH to interoperate with SONET DS3i-N-12, you must create a VC4 containing VC3s as a payload in the exact order in which they will attach to port groups on the SONET side.
With DS3-I cards in a 1:2 protection group, when the protect card is active and in the WTR condition, removing another working card from the protection group clears the WTR condition. To work around this issue, remove the working card from the protection group when the protect card is in the standby state. This issue will be resolved in a future release.
When one traffic card in a DS3I 1:N protection group is reset, and then another card is reset, there will be a loss of traffic on the second card, after the first card completes its reset, lasting until the second card completes its reset. This only occurs when the protect card tries to handle the traffic of a card that is resetting, and that card is carrying traffic because when it reset the protect card was carrying traffic for another card. This loss of traffic occurs because the protect card attempts to set its relays to handle the traffic of the working card, but the relays on the working card are also set to carry the traffic, and since the card is resetting, no software is running to switch its relays. This issue most frequently presents itself when testing a double-failure scenario: resetting two cards in a protection group. Wait until the first card completes its reset sequence before resetting the second card to prevent this problem. Configuring cards in 1:1 instead of 1:N protection should also avoid the problem. This issue will not be resolved.
DWDM Cards
The trunk port service state for the TXPP and TXP cards does not transition to unlocked-disabled,failed in the presence of an LOS-P alarm. This can occur when the payload signal for LOS-P is missing for the particular port type. This issue will be resolved in a future release.
An unexpected Mismatch Equipment Attributes (MEA) transient alarm can occur on rapidly inserting and removing a PPM. This issue can occur with a TXP_MR_10E-L for which you preprovision an OC-192 PPM. The transient alarm is raised on the PPM. This issue is resolved in Release 7.0.
Setting a Terminal loopback on an MXP-2.5G-10G trunk port causes OTUK alarms.
This can occur under the following conditions.
1. Two MXP-2.5G-10G cards are connected via the trunk ports.
2. The client ports are connected to respective STM16 line cards.
3. SDCC is enabled on the client ports and the line cards' STM16 port.
4. A terminal loopback is set on the MXP-2.5G-10G trunk port.
This terminal loopback causes OTUK-LOF and OTUK-IA alarms to be reported on both MXP-2.5G-10G trunk ports. This issue will not be resolved.
RMON TCAs are not raised on the TXPP_MR_2.5G client port after a hardware reset. To see this issue, provision two nodes with TXPP_MR_2.5G (TXP-1 and TXP-2) as follows.
Step 1 Connect the TXP-1 DWDM-A trunk to the TXP-2 DWDM-A trunk.
Step 2 Connect the TXP-1 DWDM-B trunk to the TXP-2 DWDM-B trunk.
Step 3 Create an external fiber loopback on the TXP-1 client.
Step 4 Connect the TXP-2 client to a traffic generator.
Step 5 Provision 1G FC payload on the TXP-1 and TXP-2.
Step 6 Ensure that traffic is running smoothly.
Step 7 Provision RMON thresholds using TL1 for all TXPP_MR_2.5G ports (client and trunks).
Step 8 Apply a hardware reset to the TXPP_MR_2.5G.
After the card reboots, only DWDM-A and DWDM-B (trunk) port RMON TCAs are raised in the CTC History pane. RMON TCAs for port 1 (client) are not raised. This issue will not be resolved.
RMON TCAs are not raised when the RMON history is cleared on TXPP_MR_2.5G card. To see this issue, provision two nodes with TXPP_MR_2.5G (TXP-1 and TXP-2) as follows.
Step 1 Connect the TXP-1 DWDM-A trunk to the TXP-2 DWDM-A trunk.
Step 2 Connect the TXP-1 DWDM-B trunk to the TXP-2 DWDM-B trunk.
Step 3 Create an external fiber loopback on the TXP-1 client.
Step 4 Connect the TXP-2 client to a traffic generator.
Step 5 Provision 1G FC payload on the TXP-1 and TXP-2.
Step 6 Ensure that traffic is running smoothly.
Step 7 Provision RMON thresholds using TL1 for all TXPP_MR_2.5G ports (client and trunks).
Step 8 While the traffic is running reset the RMON history by clicking the Clear button in the CTC Payload PM pane.
RMON TCAs are not raised for any port. This issue will not be resolved.
Receive client fiber removal can cause a switch from the protect to the active in a TXPP_MR_2.5G. To see this issue, perform the following steps.
Step 1 Set up two nodes with TXPP_MR_2.5G (call the nodes TXP-1 and TXP-2).
Step 2 Ensure that TXP-1 DWDM-A trunk is connected to TXP-2 DWDM-A trunk with a 100 Km span.
Step 3 Ensure that TXP-1 DWDM-B trunk is connected to TXP-2 DWDM-B trunk with a 0 Km span.
Step 4 Ensure that TXP-1 client has an external fiber loopback.
Step 5 Connect the TXP-2 client to a traffic generator.
Step 6 Provision TXP-1 and TXP-2 with FICON 1G payload.
Step 7 Ensure that traffic is running smoothly on the protected span.
Step 8 Remove the receive client fiber at the near end.
This causes the far end trunk to switch from protect to working span. Similarly, removal of the receive Client fiber at far end causes the near end trunk to switch from the protect to the working span. (Note that the traffic is already lost due to the receive client fiber pull.) To work around this issue, manually switch via CTC from the working to the protect span. This issue will not be resolved.
Incorrect ALS initiation causes a traffic outage on an FC payload. This issue can be seen by performing the following steps.
Step 1 Set up two nodes with TXPP_MR_2.5G (call these nodes TXP-1 and TXP-2).
Step 2 Connect the TXP-1 DWDM-A trunk to the TXP-2 DWDM-A trunk.
Step 3 Connect the TXP-1 DWDM-B trunk to the TXP-2 DWDM-B trunk.
Step 4 Provision the TXP-1 client with an external fiber loopback.
Step 5 Connect the TXP-2 client to a traffic generator.
Step 6 Ensure that TXP-1 and TXP-2 have 1G FC payload provisioned.
Step 7 Enable ALS on TXP-1 trunk port and set it to "Manual Restart."
Step 8 When traffic is running, remove the receive and transmit fibers on TXP1 port 1 (client). Traffic goes down and shutdown on TXP-1 port 2 (trunk) displays "No."
Step 9 Reconnect the fibers for TXP-1 port 1 (client).
ALS is now initiated on TXP-1 port 2 (trunk) and the laser shuts down. Traffic never comes back.
Note This issue is restricted to the TXPP_MR_2.5G card.
To recover from this situation, perform a manual restart or disable the ALS in this configuration. This issue will not be resolved.
When downloading Release 4.7 to nodes with Release 4.6 installed, The 15454-32MUX-O and 15454-32DMX-O report an AWG Temperature fail low alarm that subsequently clears. This also occurs when downgrading from Release 4.7 to Release 4.6, where the AWG Temperature alarm fail is high. This issue cannot be resolved.
AS-MT is not enabled in Port 3 when a loopback is applied. To see this issue, on the TXPP card, make the following 3 changes before clicking Apply:
Step 1 Change Port 2 to OOS-MT from IS.
Step 2 Change Port 3 to OOS-MT from IS.
Step 3 Change Port 2 to facility or terminal loopback.
Now, when you click Apply, CTC issues the error message: "Error applying changes to row2 peer trunk port must not be IS." Port 3 is still IS and the loopback changes are not applied. You must place Port 3 in the OOS-MT state, apply the changes, and then change the loopback to recover.
This error occurs only when all three of the above changes are attempted at the same time.
To avoid this issue, first change both the trunk ports to OOS-MT, click Apply, and then place port 2 in loopback and click Apply again. This issue will not be resolved.
With Y-cable provisioned for MXP-MR-2.5G cards, if you remove the client receive fiber on one side, the far end takes greater than 100 ms to switch away from the affected card. This issue will not be resolved.
Under certain conditions you may be unable to provision an Express Order Wire (EOW) circuit using an MXP_2.5G_10G or TXP_MR_10G card trunk port. This can occurs as follows.
Step 1 Provision an MXP_2.5G_10G or TXP_MR_10G card within a node.
Step 2 Disable OTN.
Step 3 Provision DCC on both client and trunk ports.
Step 4 Go to the Network view Provisioning > Overhead Circuits tab.
During the EOW circuit provisioning only the MXP/TXP client ports are listed for the selection. This issue will not be resolved.
After a soft reset of an OSCM or OSC-CSM card, a CONTBUS-IO alarm is raised. This issue will not be resolved.
Neither E1 nor E2 circuits are available for EOW circuits on TXP_MR_2.5 TXT in Section and Line Termination mode. This issue will be resolved in a future release.
When the FICON bridge does not receive the expected number of idle frames between data packets it will transition to SERV MODE. The MXP-MR-2.5G should not be used in scenarios where there is a FICON Bridge in place. This issue will not be resolved.
After a database restore TXPP trunk ports might report SF, resulting in a traffic outage. The SF occurs when you restore the database and then put the port OOS for DWDM cards; then the operating mode in the database is different from the current operating mode. To avoid this issue, either put the DWDM port OOS before restore the database, or, after restoring the database, reset the DWDM cards. This issue will not be resolved.
Far end traffic does not switch in line termination mode with .G709 off. This can occur with non-revertive Y-cable, and DCC enabled, under certain specific conditions. To avoid this issue, turn on .G709 when in line mode. This issue will not be resolved.
TXP-MR-2.5G F1-UDC may not be passed through in a line-terminated configuration with OTN off. This can occur with clean, OC-3/STM-1, line-terminated traffic, with OTN disabled, when you create a D1-D3 tunnel, a D4-D12 tunnel, and an F1-UDC from client to client. This issue will not be resolved.
If you go to the Overhead Circuits Tab in network view and select any User Data, F1 or User Data D4-D12 circuit type, no nXP cards are available for selection in the Endpoints. However, user Data type circuits can still be made end-to-end (where "end-to-end" refers to external cards, such as AIC to AIC) if the nXP cards are put in Transparent mode. This issue will not be resolved.
With TXPP cards, a traffic loss up to six seconds can occur during a DWDM protection switch. This behavior may be exhibited during protection switches by certain third-party fiber channel switches due to loss of buffer credits resulting in a reconvergence of the fiber channel link. This issue will not be resolved.
The 2G Fiber Channel (FC) payload data type in the TXP_MR_2.5G and TXPP_MR_2.5G cards does not support any 8B/10B Payload PM monitoring. This is by design.
Once engaged, the ALR will not restart on the trunk lines of a TXP or TXPP card. This occurs whenever ALR engages on the trunk lines of a TXP or TXPP card and the recover pulse width is provisioned to less than 40 seconds. This is a function of the trunk laser turn-on time, and the limiting recovery pulse width will vary by card. To avoid this issue, provision the pulse width to 40 seconds or more. This issue will not be resolved.
Near end and far end PMs might increment simultaneously on TXPP-2.5G cards. This can occur when two nodes have TXPP-2.5G cards and two nodes have STM16 cards in a four node network, where both TXPP-2.5G cards have STM16 SFPs on them, and are in MS (Line Termination) mode. By default, the TXPP-2.5G cards are in Splitter protection: the first DWDM port is working and the second is protect. If you remove the receive fiber of the first DWDM port on one TXPP-2.5G card, both near and far end counts begin to increment. The far end counts should not increment in this case. This issue is seen only when the Txpd cards have G709 and FEC on. If the cards have G709 and FEC off, only the near end counts will increment, as expected.
CSCeb26662 and CSCea88023
With TXP-MR-2.5G cards, when the current 1 day Optics PM rolls over, the information is inaccurate. This issue will not be resolved.
With ALS mode configured as "Auto Restart" or "Manual Restart," it is possible the ALS Pulse Duration Recovery time can be set to values out of ITU-T recommendation G.664. You can use values out of the range defined in ITU-T recommendation G.664 only in order to interoperate with equipment that lasers cannot turn on or off within the required pulse time. To stay within the specification, you can set this value to 2 seconds and up to 2.25 seconds.
On the TXPP, the default value for Tx Power High for TCAs & Alarms is too high for the trunk ports. Since Tx Power TCA and Alarm are not supported for trunk ports, this caveat is for informational purposes only.
With TXP-MR-2.5G cards, ratios are calculated incorrectly after clearing statistics. This is because after you clear statistics the entire time period becomes invalid. Once the time period rolls over again, values will be reliable for the new period.
During a Y-Cable protection switch, the client interface sends 200,000 to 300,000 8B/10B errors towards the attached Catalyst 3550 switch. The switch reacts to this large amount of 8B/10B errors by reinitializing the interface and spanning tree. The end result is that a protection switch can lead to a 30-45 second traffic hit if the switch is running spanning tree (default mode). This is expected behavior.
In a Y-Cable protection group, if GCCs are defined on both cards, both cards' active LEDs will be green. This is by design.
For the TXPP, attenuating Port 2 Rx signal, SD, and SF alarms are not declared before LOC is raised. This is due to the intrinsic design of the optical interface, which allows required BER performances with dispersion and OSNR penalties.
This can occur when Port 2 is in back to back or has low dispersions and high OSNR.
The ACTV/STBY LED shows AMBER when a 2.5G transponder is first connected. The DWDM cards introduced a new design: When all the ports are OOS on a card, the card is considered to be in standby mode.

Before configuring an SPR interface that is already part of an RPR carrying traffic, close down the POS port of the SPR interface by starting a Cisco IOS CLI session for the ML-Series card featuring the desired SPR interface and completing the following Cisco IOS configuration, beginning in global configuration mode:
Step 1 Router(config)# interface pos 0 (Enters interface configuration mode for the POS port 0 on the Delete Node.)
Step 2 Router(config-if)# shutdown (Closes the interface.)
Step 3 Router(config)# interface pos 1 (Enters interface configuration mode for the POS port 1 on the Delete Node.)
Step 4 Router(config-if)# shutdown (Closes the interface.)
In Asymmetric configuration, with autonegotiation enabled and flow control selected, an ML-series card might fail to synchronize with, or to recognize the asymmetric flow control. This issue is under investigation.
Do not use the repair circuit option with provisioned stitched Ethernet circuits. It is not known at this time when or if this issue will be resolved.
Single-card EtherSwitch
Each E100/E1000 card can be configured as a single-card EtherSwitch configuration to allow VC4-4c of bandwidth to be dropped at each card. The following scenarios for provisioning are available:
VC4-2c, VC4-2c
VC4-2c, VC4, VC4
When configuring scenario 3, the VC4-2c must be provisioned before either of the VC4 circuits.
Multicard EtherSwitch
When deleting and recreating Ethernet circuits that have different sizes, you must delete all VC4 circuits provisioned to the EtherSwitch before you create the new circuit scenario. (See the preceding "Single-card EtherSwitch" section on page 6 for details on the proper order of circuit creation.) Enable front ports so that the VLANs for the ports are carried by the largest circuit first. A safe approach is to enable the front port before you create any circuits and then retain the front port VLAN assignment afterwards. If you break the rules when creating a circuit, or if you have to delete circuits and recreate them again, delete all circuits and start over with the largest first.
If an ML-Series card running Software Release 4.6.2 or later is interoperating with an ML-Series card running Software Release 4.6.0 or 4.6.1, then the pos vcat resequence disable command must be added to the configuration of the ML-Series card running R4.6.2 or later.
On an ML-series RPR ring circuit deletion or creation causes an approximately 200 ms traffic loss. Traffic loss is expected to be less than 50 ms for RPR. To avoid this issue, from the ML-series CLI, perform a "shutdown" on both ends of the circuit prior to circuit changes. This issue will not be resolved.
You must issue a "shut" command to both ends of a POS circuit before placing the circuit OOS, and issue IS before a "no shut" command. Placing a POS circuit OOS without shutting down can cause long traffic hits. This issue will not be resolved.
You must issue a "shut" on both ends of affected POS circuits before performing a maintenance action on those circuits. If a POS circuit is restored without first issuing the shut commands, traffic loss is greater than 50 ms. When a maintenance action is taken, one end of the circuits could come up before the other. During that time, traffic is lost because the other end is not up yet. This issue will not be resolved.
When a MAC-SA is seen for the first time, it is learned, but may age out in less than 5 minutes. If the same MAC-SA is seen again before the first ages out, the entry will age out after 5 minutes, as expected. This issue will not be resolved.
Timer expiration can cause a system crash when you attempt to remove 250 Shared Packet Ring (SPR) subinterfaces using the "no int spr1" command, while Cisco Discovery Protocol (CDP) is also enabled. To avoid this issue, either turn off CDP, issue the command, and then turn CDP back on; or remove the SPR subinterfaces explicitly. This issue will not be resolved.
The broadcast packet count is always 0 for the SPR interface. The ML100 and ML1000 hardware does not support counting broadcast packets. This issue will not be resolved.
When the POS interface is removed from SPR due to a defect, while SPR is configured in immediate mode, the defect type may not be reported. This only occurs if the defect is set and clears in less then 50 ms.
ML-series cards do not appear in the Cisco Discovery Protocol (CDP) adjacencies and do not participate in the Spanning-Tree Protocol. All packets are counted as multicast.
The ML-series cards always forward Dynamic Trunking protocol (DTP) packets between connected devices. If DTP is enabled on connected devices (which might be the default), DTP might negotiate parameters, such as ISL, that are not supported by the ML-series cards. All packets on a link negotiated to use ISL are always counted as multicast packets by the ML-series card, and STP and CDP packets are bridged between connected devices using ISL without being processed. To avoid this issue, disable DTP and ISL on connected devices. This functionality is as designed.
Under certain conditions, the flow-control status may indicate that flow control is functioning, when it is not. Flow-control on the ML-series cards only functions when a port-level policer is configured. A port-level policer is a policer on the default and only class of an input policy-map. Flow-control also only functions to limit the source rate to the configured policer discard rate, it does not prevent packet discards due to output queue congestion.
Therefore, if a port-level policer is not configured, or if output queue congestion is occurring, policing does not function. However, it might still mistakenly display as enabled under these conditions. To avoid this issue, configure a port-level policer and prevent output queue congestion. This issue will not be resolved.
Issuing a shutdown/no shutdown command sequence on an ML1000 port clears the counters. This is a normal part of the startup process and there are no plans to change this functionality.
Packets without an 802.1q VLAN tag are classified as COS 0. This issue will not be resolved.
When configuring the same static route over two or more interfaces, use the following command:
ip route a-prefix a-networkmask a.b.c.d
Where a.b.c.d is the address of the outgoing gateway, or, similarly, use the command:
ip route vrf vrf-name
Do not try to configure this type of static route using only the interface instead of the address of the outgoing gateway. This issue will not be resolved.
If no BGP session comes up when VPN Routing/Forwarding (VRF) is configured and all interfaces have VRF enabled ensure that at least one IP interface (without VRF) is configured and add an IP loopback interface on each node. This issue will not be resolved.
The maximum MAC Address Learn Rate for the ML-Series cards is 1300 MAC addresses per second. This number varies based on the ML-Series control and forwarding plane loads. If the forwarding and control planes are heavily loaded, the maximum MAC Address Learn Rate could be as low as 100 MAC addresses per second. To correct a situation where an ML-Series card has stopped learning MAC addresses, reduce the load on these cards. This load limit is by design.
Oversize frames are not supported on ML100 Fast Ethernet ports. Oversize frames cause egress traffic to incur CRC, line, and fragment errors on these ports. To avoid this issue, do not send jumbo packets to ML far end ports. This is as designed.
When a VC_LOW_PATH_TUNNEL only contains unidirectional circuits, an AU-LOP critical alarm is raised. This can occur when a bidirectional tunnel goes through at least three nodes, and the AU-LOP alarm is shown on the intermediate node on the direction not used. Tunnels are bidirectional. If a tunnel does not have traffic in both directions, it will be alarmed. The alarm will be cleared when a bidirectional circuit is added to the tunnel. This issue will not be resolved.
Rarely, an LP TIM alarm displays its severity as NR instead of MJ in CTC. This can occur when a VC3 circuit is created on Port 5 and IO has detected a VC4 PLM alarm. This issue will not be resolved.
A CARLOSS alarm can take up to 3 minutes to be reported depend of the number of VLANs configured on a node. When the alarm does appear, if you clear this major alarm, the severity changes to minor, but then the alarm disappears. The alarm severity change behavior will not be changed.
MS-SPRing Functionality
Rarely, during a software upgrade of a passthrough node in an MS-SPRing, the VC3 traffic on a DS3I card might incur a traffic hit. This issue will be resolved in a future release.
When creating a MS-SPRing from the network view, the node default values for reversion are not initially used. To see this, starting with no preferences file, log into a node with CTC, and set the node default values for MS-SPRing reversion. Now, in Network view, use the MS-SPRing wizard to create a MS-SPRing. The node level default values are initially ignored while the wizard is still in operation. If you encounter this issue, you may need to change values as appropriate for your network while you are still using the MS-SPRing wizard. Once the wizard is finished, these values are saved to a preferences file and will be used henceforth. This issue will not be resolved.
Two MS-SPRings are not allowed to coexist. If you execute a manual ring switch command on one side of an MS-SPRing node and apply another manual ring switch command on other side of the node, the second manual ring switch command is rejected. This works as designed. The implementation complies with Telcordia GR-1230, R6-102.
On a four fiber MS-SPRing, restoring the database for all nodes at the same time could cause VC4-16c traffic to fail to switch. Do not restore the database for multiple nodes simultaneously. The proper procedure for restoring the database for multiple nodes is to restore one node at a time. This procedure is documented in the user documentation.
A rare hardware failure on an STM16AS card transmitter can trigger SEF on the receiving STM16AS card in a four fiber MS-SPRing (or BLSR) configuration. The BER calculations are suspended when SEF is detected, so SD or SF is never raised. Likewise SEF is not considered a signal failure condition like LOS or LOF, so a protection switch will not occur. If this occurs, use the CTC GUI to force a protection switch on the MS-SPRing (or BLSR). This issue will not be resolved.
In a two ring, two fiber MS-SPRing (or BLSR) configuration (or a two ring MS-SPRing or BLSR configuration with one two fiber and one four fiber ring) it is possible to provision a circuit that begins on one ring, crosses to a second ring, and returns to the original ring. Such a circuit can have protection vulnerabilities if one of the common nodes is isolated, or if a ring is segmented in such a way that two non-contiguous segments of the circuit on the same ring are each broken. There are two possible workarounds for this issue:
1. Manually route the circuit to avoid the "one circuit over two ring" routing scenario.
2. When routing the circuit automatically, select the Using Required Nodes/Spans option in the Circuit Routing Preference screen, then select the appropriate spans to avoid the "one circuit over two ring" routing scenario.
This issue will be resolved in a future release.
Database Restore on an MS-SPRing
When restoring the database on an MS-SPRing, follow these steps:
Step 1 To isolate the failed node, issue a force switch toward the failure node from the adjacent east and west nodes.
Step 2 If more than one node has failed, restore the database one node at a time.
Step 3 After the TCC2/TCC2P has reset and booted up, ensure that the "MS-SPRing Multi-Node Table update completed" event has occurred for all nodes in the ring.
Step 4 Release the force switch from each node.
SNCP Functionality
Traffic hits can occur in an unprotected to SNCP topology upgrade in unidirectional routing. If you create an unprotected circuit, then upgrade the unprotected circuit to a SNCP circuit using Unprotected to SNCP wizard, selecting unidirectional routing in the wizard, the circuit will be upgraded to a SNCP circuit. However, during the conversion, traffic hits on the order of 300 ms should be expected. This issue will not be resolved.
With a VT SNCP circuit, if you inject signals with a thru-mode test set into one path of the circuit in a particular order, you may not see the appropriate alarms. This can occur when you first inject LOP-P, then clear, then inject LOP-V. This issue will not be resolved.
Active XCVXL or TCC2/TCC2P Card Removal
As in MS-SPRing, you must perform a lockout on SNCP before removing an active cross connect or TCC2/TCC2P card. The following rules apply to SNCP.
Active XCVXL cards should not generally be physically removed. If the active cross connect or TCC2/TCC2P card must be removed, you can first perform an XCVXL side switch or TCC2/TCC2P reset and then remove the card once it is in standby, or you can perform a lockout on all circuits that originate from the node whose active cross connect card or active TCC2/TCC2P will be removed (performing a lockout on all spans will also accomplish the same goal). No lockout is necessary for switches initiated through CTC or through TL1.
Performance Monitoring
When you inject errors on a splitter protection card in the node's working port, CVL and ESL are incremented for the working and protect far end ports. This issue will not be resolved.
Bridge and Roll
When a rollTo leg is not receiving a good signal, and because of this the rollPending alarm is not cleared, there is no alarm indicating the reason that the RollPending alarm fails to clear. This issue is resolved in Release 7.0.
Resolved Caveats for Release 6.2
This section highlights resolved caveats for Release 6.2.
Split route circuits on some FC_MR-4 cards will take some errors at -5C to +10C ambient temperatures. This issue is resolved in Releases 6.0.1, 6.1, and 7.0.
Maintenance and Administration
Rarely, in a large network with many host routes the Proxy ARP server might run out of ring buffer storage, resulting in a subsequent failure of the driver to receive new packets. This can lead to DCC failure and loss of all connections. This issue is resolved in Releases 6.2 and 8.
When upgrading a network to Release 6.0.1, 6.1, or 7.0, where LOS-P exists on a pass-through port of a WSS for a ROADM node, if you change the circuit state to OOS,DSBLD and then again to IS-AINS, the circuit fails to go up. There are two possible workarounds:
1. Change the calibration value on the pass-through port of the WSS.
2. When the circuit is in OOS state, relaunch ANS.
This issue is resolved in Releases 6.2 and 7.0.1.
The 6.312 MHz BITS Output signal does not lock properly to its incoming reference. This issue is resolved in Release 6.2.
When a physical loopback exists on an optical trunk (Physical, facility, or terminal) Ethernet traffic in RPR might be dropped. To avoid this turn off pos interfaces before inserting a loopback. This issue is resolved in Release 6.1.
In a DWDM node the alarm correlation at node level does not work. This issue can be seen in the presence of an upstream alarm. This issue is resolved in Release 6.1.
It is not possible to create a second circuit in a metro access network. This issue is resolved in Release 6.1.
In a metro access network the amplifiers don't switch to constant gain. This issue can be seen when recreating a circuit previously deleted without re-executing ANS. Relaunching ANS manually every time avoids this issue. This issue is resolved in Release 6.1.
Electrical Cards
Long switch times (more than 60 ms) can occur on E1-42 circuits when switching via card removal or a CTC switch between differently-provisioned working cards. This issue is resolved in Release 6.2.
A protection E1-42 card might rarely fail to take over for a failed working card. There are several power supplies on the E1-42. One of them is responsible for operating the protection switches that are used for switching traffic between the working cards and the protection cards. The output of this power supply is continuously monitored. If its output voltage drops below a threshold, it is possible the card will drop traffic. When this occurs, the protection card will not take over for the failed card. An alarm will be raised, but a protection switch will not be triggered. This issue has been seen after power cycles. Monitor the alarms for this condition and switch manually if seen. Typically, traffic is not affected when this issue occurs. This issue is resolved in Release 6.2.
Common Control and Cross Connect Cards
Rarely, a CONTBUS-DISABLED alarm is raised after a TCC2 card reboot. If this occurs, reseat the failing TCC2 card. A manufacturing upgrade via ECO is available with Release 6.2.
Rarely, if the TCC2P Compact FLASH is accessed while the TCC2P is rebooting the card might not come back up. This can sometimes be simulated by resetting another card (I/O or cross-connect) in the shelf and then rebooting the TCC2P. (Tests indicate approximately one in 9 to 15 executions of this procedure will cause the issue.) To avoid this issue do not reset the TCC2P at the same time that another card in the shelf is reset. If the TCC2P does get into this state, you must remove and reinsert the failed card. This issue is resolved in Releases 6.1 and 7.0.
Nodes that are discovered through a TL1 tunnel might become permanently grayed out when the tunnel far end NE reboots. This condition can occur when one or more TL1 tunnels are active and a tunnel far end NE reboots. To recover from this condition, restart CTC. This issue is resolved in Release 6.1.
You cannot set the Gain (EXPGAIN) value using the TL1 ED-OTS command when the node is configured as Metro Access. Use CTC to set the gain in this case. This issue is resolved in Releases 6.1 and 7.0, and in maintenance Release 6.0.1.
New Features and Functionality
This section highlights new features and functionality for Release 6.2.
New Software Features and Functionality
Release 6.2 adds the following new software features.
RPR Shortest Path Load Balancing
RPR Shortest Path Load-balancing adds a capability for unicast packets added to the RPR. It allows these unicast packets to recognize and take the shortest path to the destination node.
RPR Keep-alive
The RPR keep-alive feature adds an enhanced mechanism to check on the health of an RPR ring configuration. RPR nodes exchange "keep-alive" (KA) messages (similar to "hello" protocol messages) between one another to help quickly identify a non-SONET/SDH related failure. The KA mechanism for RPR interfaces (called SPR) sends KAs on SPR links connecting adjacent nodes. This mechanism protects against failures undetected by the SONET/SDH layer. If a failure is detected, this protocol will then trigger the generation of both an alarm to alert you of the failure and an RPR wrap to reroute traffic around the failure. This capability enhances ONS 15454 RPR resiliency mechanisms currently in place.
Alarm Generation on CRC Errors
The CRC_ALARM is raised on Ethernet interfaces when the rate of Ethernet frames with CRC errors exceeds a defined threshold. A raised CRC_Alarm initiates an RPR wrap. For the wrap to occur, the RPR POS interface (SPR) needs to belong to an RPR, and the RPR wrap option must be configured on the RPR wrap trigger.
Gigabit Ethernet Remote Failure Indication
Remote Failure Indication (RFI) is part of the 802.3z standard and is sent in order to exchange failure information as a part of link negotiation. This feature improves communication with non-Cisco equipment and is now added to the ML-Series card.
ML-Series Card Version Up
The ML-Series card Version Up feature allows you to independently upgrade ML-Series cards as part of the overall software upgrade process. With this feature enabled, you first activate the node, initializing the upgrade of all cards that are not ML-Series cards, then in a second pass you update the ML-Series cards (by initiating a software reset). Version Up is disabled by default.
You can initiate individual upgrades for each ML-Series card at any time after the initial node activation.
Note The software upgrade is not complete until all ML-Series cards have been upgraded. Consult the user documentation for specific effects of using the Version Up feature before you perform an upgrade.
In the case of redundant ML-Series cards, individual upgrades allow time to verify the proper operation of the first card before the second card is upgraded. No ML-Series card is upgraded until you specifically reset that card.
You can perform a Version Up upgrade using CTC or CTM. The Version Up feature is only supported on the ONS 15454 and ONS 15454 SDH platforms. TL-1 does not support Version Up, and you cannot enter TL-1 commands during an upgrade in which Version Up is turned on.
ML-Series Enhancements—EoMPLS
Release 6.2 supports three important ML-Series EoMPLS enhancements (these features were introduced in Release 5.0.5):
•EoMPLS over point-to-point circuits using GFP framing
•EoMPLS using RSVP signaled MPLS Traffic Engineering Tunnels
•FCS preservation over EoMPLS tunnels
With Release 6.2 ML data card enhancements, service providers can offer customers services that make use of EoMPLS-based implementation of pseudo wires over GFP, and also MPLS Traffic Engineering Tunnels using RSVP-TE as the signaling protocol.
EoMPLS pseudo wires over point-to-point circuits using GFP framing, without RPR, are supported on data cards for creating point-to-point pseudo wire circuits across the data network. Each data card supports 24 MPLS-TE tunnels, which can be used for carrying traffic over E-LSP connections. Data cards support MPLS-TE tunnels with RSVP signaling control of the EoMPLS over GFP pseudo wires. You have the option of selecting RSVP as the control protocol during the EoMPLS creation.
Data cards also support Ethernet Frame Check Sequence (FCS) preservation across EoMPLS over GFP pseudo wires. You have the option of selecting Ethernet FCS preservation, or not. The default value for FCS preservation is "off."
Each access port on the data card can be simultaneously provisioned for both EoMPLS (to support point-to-point connections) and QinQ (to support multipoint connections). Data cards interoperate with the Tellabs 8860 for setup of EoMPLS connections. Interoperability testing can be done prior to deployment.

Spotify, the jukebox service now rolling out via invite in the U.S., has a neat feature where users can publish and subscribe to each other's playlists.
You have to love that tech leaders like Reed Hastings and Mark Zuckerberg are partaking in public playlists and revealing that some of their mutual favorite listens are Madonna, Lady Gaga and Taylor Swift. (Did guilty pleasure pop music help break the ice when the Netflix CEO recently agreed to join the Facebook board?)
Hastings's "LoveGame" playlist does have Gaga, but it's also a mix of older and sentimental favorites like Cat Stevens's "Wild World" and Savage Garden's "Truly Madly Deeply."
Meanwhile, Zuckerberg has some artist-specific playlists for favorites like Green Day and Jay-Z, as well as a curated mix of Top 40 stuff called "Like a G6."
Facebook and Spotify have a close corporate relationship, and many other Facebookers appear to be active Spotify users. Facebook CTO Bret Taylor's "Good Songs" includes selections from Death Cab for Cutie and The Shins, while VP of Product Chris Cox has curated an extensive collection of "Island Music."
Quora's Mark Bodnick has an impressive 75 public playlists, including lots of hip hop and a little bit of "Glee."
Napster founders Sean Parker (an active investor in Spotify) and Shawn Fanning both have a bunch of playlists up, including Parker's "effervescent groove" and Fanning's "Prozac Plz."
YouTube co-founder Steve Chen has a country playlist titled "Always On My Mind" and YouTube Director of Product Management Hunter Walk has a 218-track long "Hip Hopps" mix.
Spotify CEO Daniel Ek is of course an active user of his own service, with 198 public playlists, including some Swedish music and the slightly TMI "My girl."
(Turntable.fm, another social music service, has also been enthusiastically used by tech folks, though you have to jump into a room in real-time to experience other users' DJ choices.)
On the topic of social music, Ek said last week at the Fortune Brainstorm Tech conference that "in general people are comfortable sharing their music." But he added: "It has two exceptions, though: Lady Gaga and Britney Spears."
Not always!

The following is an excerpted article David Brooks wrote for the N.Y. Times.
"When Arthur Brooks was 24, he was playing the French horn in a chamber music concert in Dijon, France. He noticed a beautiful woman smiling at him from the front row, so, after the recital, he made a beeline for her and introduced himself.
"Within seven seconds he came to two realizations. First, he was going to marry this woman. Second, she didn't speak a word of English, and he didn't speak a word of Spanish or Catalan, which were her languages.
"When he got home, he realized that if he was going to have a chance with Ester he was going to have to show commitment. So he quit his job in America, moved to Barcelona and went to work with the Barcelona orchestra. Over the next few years, he learned Spanish and Catalan and Ester learned English. They have been happily married for 22 years.
"'Sometimes you just have to be all in,' says Brooks (who is no relation). 'You have to go beyond cold utilitarian analysis.'
"Brooks later became a social scientist and is now president of the American Enterprise Institute, probably the most important think tank on the American right. He has emerged as one of the most ardent defenders of the free enterprise system. But the humanist that he is, he has primarily defended capitalism on moral terms. He's criticized Republicans for defending capitalism on materialistic grounds—because it makes some people rich. Republicans, Brooks says, have an overly small-business focus. They talk as it everybody should become an entrepreneur.
"The real moral health of an economic system, he argues, can be measured by how well it helps all people make an enterprise of their life. Whether they work at odd jobs or at a nongovernmental organization or at a big company, do they get to experience the joy of achievement? Do they know that their work amounts to something?
"He's pointed out that the percentage of people in the world living on $1 a day has declined by 80 percent since 1970s, adjusting for inflation. That's the greatest increase in human possibility in human history. The primary cause is globalized capitalism.
"But capitalism now faces its greatest moral crisis since the Great Depression. The nature of that crisis can be captured in two statistics. When Facebook entered a deal to buy WhatsApp, it agreed to pay a price equal to $345 million per WhatsApp employee. Meanwhile, the share of the economic pie for the middle 60 percent of earners nationally has fallen from 53 percent to 45 percent since 1970.
"This economy produces very valuable companies with very few employees. Meanwhile, the majority of workers are not seeing income gains commensurate with their productivity levels.
"This puts a strain on the essential compact that you can earn your success. As Joel Kotkin has argued, the middle class is being proletarianized, and the uneducated class is being left behind.
"To his credit, Brooks is responding aggressively to this moral challenge, in a way that is providing a needed jolt to Republican circles. Over the last two days, for example, he had the Dalai Lama, a self-described Marxist, over at the American Enterprise Institute to discuss the morality of capitalism. Jonathan Haidt, of the Stern School of Business at New York University, challenged the mostly Republican audience to invent a new capitalist narrative, going beyond the simple demonization and celebration narratives.
"Brooks recently published a daring piece in Commentary magazine on a conservative social justice agenda. It was called 'Be Open-Handed Toward Your Brothers.'
"He pointed out that conservatives love to talk about private charity, but, if you took the entire $40 billion that Americans donate to human service organizations annually, it would be enough money to give each person who receives federal food assistance only $847 per year.
"Instead, Republicans need to declare a truce on the social safety net. They need to assure the country that the net will always be there for the truly needy. Then they need to point out that it is the web of middle-class entitlements, even the home mortgage deduction, that really threaten benefits to the poor.
