¾ To add a read-write community string (v2admin), take these 2
steps:
1. Add a new row to the snmpCommunityTable with CommunityName v2admin.
2. Add a row to the vacmSecurityToGroupTable for SecurityName v2admin, GroupName
ReadWriteGroup and SecurityModel snmpv2c.
¾ To delete the read-write community string (v2admin), take these 2
steps:
1. If v2admin is being used as the trap community string, follow the procedure for
changing the trap community string. (Refer to the procedure below.)
2. Delete the snmpCommunityTable row with a CommunityName of v2admin and
GroupName of ReadWriteGroup.
¾ To change the only read-write community string from v2admin to
v2mgr, take these 4 steps:
1. Follow the procedure above to add a read-write community string to a row for v2mgr.
2. Set up the EM so that subsequent ‘set’ requests use the new community string,
v2mgr.
3. If v2admin is being used as the trap community string, follow the procedure to change
the trap community string (see below).
4. Follow the procedure above to delete a read-write community name in the row for
v2admin.
¾ To change the trap community string, take these 3 steps:
1. Add a row to the vacmSecurityToGroupTable with these values:
• SecurityModel = 2
• SecurityName = the new trap community string
• GroupName = TrapGroup, ReadGroup or ReadWriteGroup
• The SecurityModel and SecurityName objects are row indices
2. Modify the SecurityName field in the sole row of the snmpTargetParamsTable.
3. Remove the row from the vacmSecurityToGroupTable with SecurityName = the old
trap community string.
Notes:
• The procedure above assumes that a row already exists in the
snmpCommunityTable for the new trap community string. The trap
community string can be part of the TrapGroup, ReadGroup, or
ReadWriteGroup. If the trap community string is used solely for
sending traps (recommended), then it should be made part of the
TrapGroup.
• You must add GroupName and RowStatus on the same set.
