I have two Cisco 4500 switches connected with each other through a giga link. I receive this message on one of the 4500 on the gigaport connected to the other 4500. This message is recived on daily basis. Only difference is the VLAN ID keeps changing to VLAN 11, 15,13,12. All these VLANs are user VLANs connected to the both 4500 core switches.
I am not sure the cause of the problem. Any help would be appreciated
