Hi Dave ,
Thank for very much your effort. 
The SNMP proxy is working now but it times out waiting for response for some
queries . Is it possible to increase the 
Default time out value for the  proxied SNMP requests ? Is  there any
directive available in  snmpd.conf for  this purpose ?

Also , can the proxy work with the subagents ? What I mean here is it
possible for the net-snmp subagent to respond to both 
Agentx protocol messages and proxied snmp queries ? 



Thanks & Regards,
Rajendra Singh

Which snmpd.conf?   There should be two (one for A, and one for B).
I'm assuming this is the A version.

That configuration is set to allow read access to the subtree   .1.3.6.1.2.1
(and nothing else)  when using the community "testgroup2".

Forget about the proxy stuff for now.
You've got problems before that kicks in.

That's correct.
You are asking for values underneath .1.3.6.1.4.1, which is not part of the
accessible subtree .1.3.6.1.2.1

So the main SNMP agent (A) is rejecting this request, without ever bothering
to ask the proxied agent at all.



I would strongly recommend that you don't bother with the full
com2sec/group/view/access directives.
   Just use "rocommunity" - it's *much* simpler.

You'll also need to set up access control on the proxied agent B, to allow
the agent A to query it.

Make sure that you can:
   a)  query the full OID tree on agent A from your main management station.
   b)  query the subagent B from the system where A is running
          (using snmpgetnext/snmpwalk/etc)

Do this *before* looking at the proxy directive itself.
You need to get the individual bits working before you start trying to
stitch them all together.
