GLYPH<SM590000> Submit Changes: Select this button to submit changes to any of the global settings,  including the fields SNMP Version, Enable SNMP Traps, and Trap Community Name. GLYPH<SM590000> Destination Settings: Use the Destination Settings table to add, modify, or delete a  destination for SNMP trap logs. The user can add, modify, or delete a maximum of 16  destination settings at one time. GLYPH<SM590000> IP address: The IP address of the SNMP server. This value can take any of the following  formats: IPv4, IPv6, a  host name  that is resolved by the system (such as  localhost ), or an  FQDN if a domain name server (DNS) is provided. A value in this field is required. GLYPH<SM590000> Port: The port to which the SNMP trap logs are sent. This value must be  0 - 65535. A value in this field is required. GLYPH<SM590000> Prefer local cache for scratch mount requests – The Copy Mode field that is defined by the MC for the mount has a value other than No  Copy defined for the local cluster. – The Copy Mode field that is defined for the local cluster is not Deferred when one or  more peer clusters are defined as Rewind Unload (RUN). Note:  A user with read-only permissions cannot modify the contents of the Destination  Settings table. Tip:  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 . 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 ” is also  3afa::200:2535:e8ef:91cf ”.

Destinations are changed in the vital product data (VPD) when they  are added, modified, or deleted. These updates do not depend on the user clicking  Submit  Changes .
