When troubleshooting a problem with Access Control lists, one of the things you would want to do is to clear the counters on the ACL matches.
In Cisco IOS, you can clear the ACL Matches counters as follows:
Clear Counters on All ACLs
ciscorouter# clear access-list counters
This clears the matches on all the ACLs on the cisco router or switch.
Clear Counters on Specific ACLs
ciscorouter# clear access-list counters 60
In this, we clear the matches on the ACL number 60. You can also use the name of the ACL instead of ACL number.
To verify the counters are cleared,
ciscorouters# show access-lists
This should show the access-list with the counters cleared on the ACL(s)
