Package uk.co.westhawk.snmp.beans

Class UsmBeingDiscoveredBean

java.lang.Object

uk.co.westhawk.snmp.beans.UsmBeingDiscoveredBean

All Implemented Interfaces:

EventListener, RequestPduListener

public class UsmBeingDiscoveredBean
extends Object
implements RequestPduListener

This bean handles being discovered as an authoritative engine by an non-authoritative engine (SNMPv3 only).

The discovery process consists of two steps: 1. first the SNMP engine ID has to be discovered, second the timeline details of the SNMP engine ID have to be discovered.
2. For the last step the username of the principal is needed.
All these parameters should be provided by (your own) UsmAgent.

This class is not very efficient. The private context discEngineIdContextIn will be the same for every SnmpContextv3 that creates this bean.

See SNMP-USER-BASED-SM-MIB.
