[AGENT++] FW: SNMP V3 contexts with agentX++(mention our versions as well)

[Frank Fock]

Santosh,

AgentX++ subagents do support non-default contexts as well.
Just add the objects you want to support in a context on behalf
of it, in the same way as you would do in a AGENT++ agent, except
of leaving out the VACM configuration.

Best regards,
Frank
