public class SnmpContextv3Discovery
extends SnmpContextv3Basis

This class contains the SNMP v3 discovery context that is used by UsmBeingDiscoveredBean, when this stack is being discovered. Most of the work is done by SnmpContextv3Basis.

Now that the stack can send traps and receive requests, it needs to be able to act as an authoritative SNMP engine. This is done via the interface UsmAgent. The DefaultUsmAgent is not guaranteed to work; agents (or rather authoritative engines) should provide a better implementation.
