You can apply ACLs to Layer 2 interfaces on a switch. Port ACLs are supported on physical interfaces and EtherChannel interfaces.


The following access lists are supported on Layer 2 interfaces:


•Standard IP access lists using source addresses


•Extended IP access lists using source and destination addresses and optional protocol type information


•MAC extended access lists using source and destination MAC addresses and optional protocol type information


As with router ACLs, the switch examines ACLs associated with features configured on a given interface and permits or denies packet forwarding based on how the packet matches the entries in the ACL.


Hope that helps.
