11.1 Access Control List Fundamentals  
  11.1.5 Verifying ACLs  
There are many show commands that will verify the content and placement of ACLs on the router.

The show ip interface command displays IP interface information and indicates whether any ACLs are set. The show access-lists command displays the contents of all ACLs on the router. To see a specific list, add the ACL name or number as an option for this command. The show running-config command will also reveal the access lists on a router and the interface assignment information.

These show commands will verify the list contents and placement. It is also a good practice to test the access lists with sample traffic to ensure that the access list logic is correct.
