Hi Paresh,

Yes, AGENT++ comes with a proxy forwarder application
is defined in the SNMPv3 RFCs. The class that implements
it is "ProxyForwarder".

You need _SNMPv3 defined, in order to be get the
ProxyForwarder class to be compiled. But you will
not need to use SNMPv3 to talk to the agent in order
to be able to use the proxy forwarder application.
You "simply" will have to configure the SNMP-COMMUNITY-MIB,
the SNMP-PROXY-MIB, and the SNMP-TARGET-MIB properly.

You will find more details in the SNMPv3 RFCs and in the
book "A Pratical Guide to SNMPv3 and Network Management"
by D. Zeltserman.
