Whats the difference between master agent and proxy forwarder?
A. An SNMP master agent can route parts of an SNMP request to multiple subagents. The subagents are completely hidden from the SNMP manager. The manager only sees a single SNMP entity, the master agent. On the contrary, in a proxy forwarder application, the manager needs to be aware of all the proxied agents. It needs to build a request targeted to a single specific subagent, and it needs to include in the request some information that enables the proxy forwarder application to determine which subagent is the targeted of the request.
