ACE counter operation

For a given ACE in an assigned ACL, the counter increments by 1 each time the switch detects a packet that matches the criteria in that ACE, and maintains a running total of the matches since the last counter reset.

This ACL monitoring feature does not include hits on the "implicit deny" that is included at the end of all ACLs.

Also, if the show statistics command does not show any ACE hit activity at first use, re-execute the command.
