Draft Document for Review February 7, 2020 3:15 pm 8464ch09_Oper.fm Note:  Any modifications to IP addresses on the accessing cluster interrupt access to  that cluster for all current users. If the accessing cluster IP addresses are modified, the  current users are redirected to the new virtual address. The following fields are displayed on this tab: GLYPH<SM590000> IPv4  Select this option if the cluster can be accessed by an IPv4 address. If this option is  disabled, all incoming IPv4 traffic is blocked, although loop-back traffic is still permitted. If this option is enabled, specify the following addresses: –< Cluster Name > IP address  An AIX virtual IPv4 address that receives traffic on both  customer networks. This field cannot be blank if IPv4 is enabled. – Primary Address  The IPv4 address for the primary customer network. This field  cannot be blank if IPv4 is enabled. – Secondary Address  The IPv4 address for the secondary customer network. This field  cannot be blank if IPv4 is enabled. – Subnet Mask  The IPv4 subnet mask that is used to determine the addresses present  on the local network. This field cannot be blank if IPv4 is enabled. – Gateway The IPv4 address that is used to access systems outside the local network. A valid IPv4 address is 32 bits long, consists of four decimal numbers, each 0 - 255,  separated by periods, such as  98.104.120.12 . GLYPH<SM590000> IPv6: Select this option if the cluster can be accessed by an IPv6 address. If this option is  disabled, all incoming IPv6 traffic is blocked, although loop-back traffic is still permitted. If  the user enables this option and does not designate any other IPv6 information, the  minimum required local addresses for each customer network interface automatically is  enabled and configured by using neighbor discovery. If this option is enabled, the user can  specify the following addresses: – Primary Address  The IPv6 address for the primary network. This field cannot be blank  if IPv6 is enabled. – Secondary Address  The IPv6 address for the secondary network. This field cannot be  blank if IPv6 is enabled. – Prefix Length  The IPv6 prefix length that is used to determine the addresses present  on the local network. The value in this field is an integer 1 - 128. This field cannot be  blank if IPv6 is enabled. – Gateway  The IPv6 address that is used to access systems outside the local network. GLYPH<SM590000> DNS Server  The IP addresses of any domain name server (DNS), separated by commas.  DNS addresses are needed only when specifying a symbolic domain name rather than a  numeric IP address for one or more of the following types of information: – Primary Server URL on the Add External policy window – Encryption Key Server (EKS) address – SNMP server address – Security server address A valid IPv6 address is a 128-bit long hexadecimal value that is separated into  16-bit fields by colons, such as  3afa:1910:2535:3:110:e8ef:ef41:91cf . Leading zeros can be omitted in each field so that  :0003:  can be written as  :3: . A  double colon (::) can be used once per address to replace multiple fields of zeros.  For example,  3afa:0:0:0:200:2535:e8ef:91cf  can be written as  3afa::200:2535:e8ef:91cf . Chapter 9. Configuring and operating the IBM TS7700  485
