LAN duplicate MAC Address; resuming
A frame was received in which the source MAC
Address was the same as this station’s MAC Address. All
stations on a network must have a unique MAC address.
Immediately isolate the offending station; it may be
necessary to turn it off or disconnect it from the network.
This station remains Online unless you intervene to take it
Offline.
