Though there is no other 4574| | application types that currently need discovery (NRs 4575| | accept notifications from contextEngineIDs that derive 4576| | from the NO not the NR). Also a lame excuse for doing 4577| | it here. 4578| | 3) Less important technically, but the net-snmp agent 4579| | doesn't currently handle registrations of different 4580| | engineIDs either and it would have been a lot more work 4581| | to implement there since we'd need to support that 4582| | first. :-/ Supporting multiple context engineIDs should 4583| | be done anyway, so it's not a valid excuse here. 4584| | 4) There is a lot less to do if we trump the agent at this 4585| | point;
