Symptoms of Duplicate MAC Addresses in VLAN
Environments
There are no definitive events or statistics to indicate the presence of duplicate
MAC addresses in a VLAN environment. However, one symptom that may
occur is that the duplicate MAC address can be seen in the Port Address Table
for more than one port. You can do a search for the suspected MAC address
in the switch’s address table and if there is a duplicate MAC address problem,
the address will be found in the table associated with one port at one moment,
and then later associated with a different port.
