Step 6
Monitoring IPv4 ACLs
You can monitor IPv4 ACLs by displaying the ACLs that are configured on the switch, and displaying 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 this table to display this information.
