Configuration of Community Strings using SNMP
To configure read-only and read-write community strings, the EM must use the SNV7111-
COMMUNITY-MIB. To configure the trap community string, the EM must also use the
snmpVacmMIB and the snmpTargetMIB.
To add a read-only community string (v2user):
Add a new row to the srCommunityTable with CommunityName v2user and GroupName
ReadGroup.
To delete the read-only community string (v2user):
If v2user is being used as the trap community string, follow the procedure for changing
1
the trap community string (see below).
Delete the srCommunityTable row with CommunityName v2user.
2
To add a read-write community string (v2admin):
Add a new row to the srCommunityTable with CommunityName of v2admin and
GroupName ReadWriteGroup.
To delete the read-write community string (v2admin):
If v2admin is being used as the trap community string, follow the procedure for changing

Delete the srCommunityTable row with a CommunityName of v2admin and GroupName
2
of ReadWriteGroup.
To change the only read-write community string from v2admin to v2mgr:
Follow the procedure above to add a read-write community string to a row for v2mgr.

Set up the EM so that subsequent set requests use the new community string, v2mgr.

If v2admin is being used as the trap community string, follow the procedure to change

the trap community string (see below).
Follow the procedure above to delete a read-write community name in the row for

v2admin.
The following procedure assumes that a row already exists in the srCommunityTable 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
