Hi Dave, Thanks a lot for the response.
Here is what we have observed when a Getnext is sent with Oid less than What subagent has registered for: 1. Master agent is sending one getnext with BaseOid. 2. Subagent is seeing one get with BaseOid and One Getnext with BaseOid. Sending Get and GetNext must be happening in the sub-agent library. From the logs we could see that master is sending only one getnext with BaseOid the subagent has registered with. This is in-line with your explanation. Please give your inputs on our handling of Get and Getnext requests: 1. Whenever Get request is received, respond back with "NOSUCHNAME" (Our mgmt station doesn't send a get). 2. Whenever a GetNext request with the baseoid is received, respond back with "NOSUCHNAME" if the request has come from anybody other than our mgmt station. Does the above implementation can cause any issues to other subagents or the master agent or other mgmt stations.
