Hmmm you got me curious so I looked at a few of our switches as we don't use but vr also and it seems if you don't define the vr when you are setting up snmp traps and communities it sets them up under both. Even though there is not an ip configured on vr-mgmt I still get a few hits to it that get dropped and also have drps on the vr-def ... I understand what all the other stats are but am now curious as to what the drops represent....
May be because in switch there is more then one VR (for default - is VR-Def, VR-Mgmt, also can be used added VRs)?
sh man - show summary information.
sh snmp vr - show counters in specific VR
