VLAN Physical Address Changed

Unanswered Question
May 13th, 2008

Has anyone seen this before:

We are monitoring our Cat 3750 using Solarwinds Orion. It is showing that 3 of our VLAN interfaces' physical address has changed: VLAN100 - "VLAN" Physical Address changed from 001CDF739CA to 001CDF7392CB, VLAN1 - "VLAN" Physical Address changed from 001C0F7392CB to 001c0F7392CD, VLAN51 - "VLAN" Physical Address changed from 001C0F7392C9 to 001C0F7392CA. This is the second time something like this has happened on this switch.

I have this problem too.

'Physical Address changed' and 'Interface Index changed' are occurring regularly at a 62 - 63 minute interval. (Which would be more consistent with theNMS polling the switch than the switch sending traps) . Suggested to that if possible could he delete off Cat 3750 from Solar Winds system and then add them back in again - this will force his system to re-discover the if Table for each switch.
