The Sub-Agent

The sub-agent in our example is a stand-alone agent which serves a subset of the RFC1213 MIB. Since it implements no proxies of its own, it is just a plain agent which responds to SNMP management requests that happen to originate from a proxy object. Any SNMP manager could also send requests to this agent.

Stand-alone agents are covered in "Stand-Alone SNMP Agents". Since this stand-alone agent contains no code that is specific to its role as a sub-agent, we will not repeat its program listing here. The StandAloneAgent.java file only contains some extra code for reading its assigned port from the command line. We will use this to launch the agent on a known port to which the proxy can connect.
