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 31-2
to display this information.
You can also display information about VLAN access maps or VLAN filters. Use the privileged EXEC
commands in
Table 31-3 to display VLAN map information.
