Class DefaultUsmAgent

java.lang.Object

  +--uk.co.westhawk.snmp.stack.DefaultUsmAgent

All Implemented Interfaces:

UsmAgent

public class DefaultUsmAgent

extends java.lang.Object

implements UsmAgent

This implementation of UsmAgent tries to discover the parameters by doing the default USM discovery process on localhost.

Note that it is not guaranteed that the agent will allow discovery by itself. Also, if the SNMP agent reboots while the stack is running, it will not pick up the new boots and time.

Users are advised and encouraged to provide a better, more accurate implementation of UsmAgent.
