About resetting ACE hit counters to zero
-
Using the
clear statistics
command, see Static ACL performance monitoring -
Removing an ACL from an interface zeros the ACL's ACE counters for that interface only.
-
For a given ACL, either of the following actions clear the ACE counters to zero for all interfaces to which the ACL is assigned:
-
Adding or removing a permit or deny ACE in the ACL.
-
Rebooting the switch.
-
Resetting ACE hit counters to zero
The following example uses the counter activity to demonstrate using
clear statistics
to reset the counters to zero.
