Do we have any introduction to usage of ProxyForwarder?
I want to forward outside snmp request to another device and got its response pdu and then feed back the pdu to outside requestor.
Not sure if ProxyForwarder could achieve this.
Appreciated if you could give some suggestions.
Yes, the ProxyForwarder can be used for that and it is controlled using the SNMP-PROXY-MIB. See https://tools.ietf.org/html/rfc3413
There is no other documentation, but I think the RFC provides sufficient info.
