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.

ACE counter operation

In ACL line 10 below, there has been a total of 37 matches on the ACE since the last time the ACL's counters were reset.

(37) 10 permit icmp ::/0 fe80::20:2/128 128

NOTE:

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.
