at a customer site I found false 'Vlans Trunk Mismatch' for CIGESM connected to a Cat6500. A SNMPwalk on 'vlanTrunkPortsVlanEnabled.<ifindex> against the trunk port on both sites of the trunk does not show any difference, so I assume it is a bug in CM and not in the SNMPagent on the device. Another possibility is that 'vlanTrunkPortVlansEnabled' is the wrong OID and the discrepancy report algorithm uses some other OIDs...
Does anybody else see these false positives?
Attached is the output of snmpwalk on several OID along with the discrepancy report.
I have not produced a patch for this bug as it requires some architectural changes, and more code testing is required before releasing. This bug should be fixed in CM 5.0.4.
