If the various subagents register individual instances (rather than a complete table), then this should work as expected. There is a mechanism within the AgentX protocol to register OID "slices", which can be used to handle different rows of the table among the various subagents. Note that this feature has not been widely used in the Net-SNMP agent, so there may well be problems with this implementation. We would look forward to hearing of your experiences. > Or say there can be some other parameter (for example the community)... can > it happen that GET request for the same OID with community C1 goes to > subagent-2 and with community C2 goes to subagent-2 (where both subagents > have registered the same MIB with the same snmpd). Yes - you can register the MIBs multiple times, using a suitable "context" string each time. An SNMPv3 request can specify this context directly and the agent will direct the request to the appropriate subagent. An SNMPv1/2c request can be mapped to the appropriate context using the community string. It's difficult to suggest which is the better approach for you, without knowing more about the MIBs you need to support. If you are talking about having duplicate copies of the exact same OIDs (e.g. scalar MIB objects), then you need to look at using contexts. If the MIB objects are all from tables, and particularly if you want to be able to retrieve information from several subagents as part of the same request, then you need to look at using MIB slices.
