Until R12.52 SP1 CR04, we do not support changing the communities within the sub-agent to anything else other than "public".
We can modify the Master agent to a different community, however changing the sub-agent to anything stops SNMP from working.
Customer have concerns over using "public" communities. There needs to be the flexibility for the SNMP Sub-Agent to function on different communities other than "public".
Support Case Number : 00338473.
We are asking for CA SSO Support for other communities in the sub-agent (which is tied into the Master Agent supported community) and also documentation be updated with changes to be done in Master Agent and Sub-Agent to support a different community other than public.
