show mac address-table
Usage Guidelines
This command displays the MAC address table for the switch. Specific views can be defined by using
the optional keywords and values. If more than one optional keyword is used, all of the conditions must
be true in order for that entry to appear.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output
do not appear, but the lines that contain Output appear.
