Hello,
I am tryin to figure out how traps get sent in differnt versions of
SNMP when RMON is in the loop (does RMON have to be involved - I
suppose so?).

AFAIK in SNMP V 1-3 an event index hits the RMON eventTable and
determines the eventCommunity.
In the case of SNMP V1 this eventCommunity gets passed to
agentTrapDestTable and this specifies the type and destination.
I am not quite clear on if use of SNMP V1 means you necessarily get a
Trap V1. Some docs I have read describe this as a notification (but I
thought that notifications were V3).

SNMP V3 seems to reference the RMON eventTable in the same way, get the
eventCommnunity and reference the snmpNotifyTable (and later to the
snmpTargetAddrTable and snmpTargetParamsTable).
And the we get a Notification (rather than a trap).

I dunno about SNMP V2 though, does using SNMP V2 mean you always get a
trap V2?
And when you use SNMP V3 does that mean you cannot get a Trap V2 - just
a Notification?

Any fine manuals that explain this that I should read?
Although I should mention I have looked at lots of RFCs amd the OReilly
SNMP book and I am still not clear of this.
Though I daresay if some could clarify the points above, I might reread
the fine manual and actually understand it proper!

TIA

Tony
