com.sun.management.snmp.agent.SnmpErrorHandlerAgent
public class SnmpErrorHandlerAgent
A simple MIB agent that implements SNMP calls (get, set, getnext and getbulk) in a way that only errors or exceptions are returned. Every call done on this agent fails. Error handling is done according to the manager's SNMP protocol version.
It is used by SnmpAdaptorServer
for its default agent
behavior. When a received Oid doesn't match, this agent is called to
fill the result list with errors.
