Information
If you do not enter an access-list name, all MAC access-list counters clear. The counter counts the
number of packets that match each permit or deny statement in an access list. To get a more recent
count of packets matching an access list, clear the counters to start at zero. To view access-list
information, use the show access-lists command.
