After you have defined and applied ACLs, you can display various information about them, such as what ACLs are configured on the switch, what interfaces and VLANs an ACL is applied to, and information about configuration conflicts or resource usage related to your ACLs.
To display the contents of one or all current IP and MAC address ACLs or a specific ACL, numbered or named, use the following command:
3550A#show access-lists [number | name]
To display detailed configuration and status information of an interface, use the following command. Note that if IP is enabled on the interface and ACLs have been applied by using the ip access-group interface configuration command, the access groups are included in the display.
