Displaying IPv4 ACL Configuration
You can display the ACLs that are configured on the switch, and you can display the ACLs that have
been applied to interfaces and VLANs.
When you use the ip access-group interface configuration command to apply ACLs to a Layer 2 or 3
interface, you can display the access groups on the interface. You can also display the MAC ACLs
applied to a Layer 2 interface. You can use the privileged EXEC commands as described in
Table 1-2 to
display this information.
