Usage Guidelines
You can apply MAC ACLs only to ingress interfaces. If an IP access group is already defined for an
interface, you cannot apply this command to the interface.
After receiving the packet, the switch checks the match conditions in the ACL. If the conditions are
matched, the switch forwards the packet.
If the specified ACL does not exist, the switch forwards all packets.
For more information about configuring MAC extended ACLs, see the "Configuring Network Security
Note
with ACLs" chapter in the software configuration guide for this release.
Examples
This example shows how to apply a MAC extended ACL named macacl2 to an interface:
Switch(config)# interface fastethernet0/1
Switch(config-if)# mac access-group macacl2 in
You can verify your settings by entering the show mac access-group privileged EXEC command.
