java.lang.Objectsnmp.SNMPv1AgentInterface
The class SNMPv1AgentInterface implements an interface for responding to requests sent from a remote SNMP manager. The agent simply listens for requests for information, and passes requested OIDs on to concrete subclasses of SNMPRequestListener. These are expected to retrieve requested information from the system, and return this to the agent interface for inclusion in a response to the manager. The approach is that from version 1 of SNMP, using no encryption of data. The agent listens on UDP port 161, the standard SNMP port, unless an alternate (non-standard) port is supplied in the conbstructor.
