from the table.
To clear static MAC addresses from the table, use the no mac-address-table static command.
If the clear mac-address-table dynamic command is entered with no options, all dynamic addresses
are removed. If you specify an address but do not specify an interface, the address is deleted from all
interfaces. If you specify an interface but do not specify an address, the switch removes all addresses on
the specified interfaces.
