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.
