Though there is no other 4516| | application types that currently need discovery (NRs 4517| | accept notifications from contextEngineIDs that derive 4518| | from the NO not the NR). Also a lame excuse for doing 4519| | it here. 4520| | 3) Less important technically, but the net-snmp agent 4521| | doesn't currently handle registrations of different 4522| | engineIDs either and it would have been a lot more work 4523| | to implement there since we'd need to support that 4524| | first. :-/ Supporting multiple context engineIDs should 4525| | be done anyway, so it's not a valid excuse here. 4526| | 4) There is a lot less to do if we trump the agent at this 4527| | point;
