Thanks Christophe for the reply and reading through I can see a little confused, to say the least !
OK hope this clarifies it
In this example from a test checkpoint we sent a trap using the Mib as defined in what spectrum sees (10.1.6.2) and then loaded up the MIB in a trap receiver tool. As you can see the one sent 10.1.6.2 does not resolve to the trap as the system sees the trap as 10.1.2 which is then resolved with the correct trap description (top right).
I hope that clarifies it. ?
Cheers,
Ian
