This example shows how to create a MAC-Layer ACL named mac_layer that denies dec-phase-iv traffic
with source address 0000.4700.0001 and destination address 0000.4700.0009, but permits all other
traffic:
Router(config)# mac access-list extended mac_layer
Router(config-ext-macl)# deny 0000.4700.0001 0.0.0 0000.4700.0009 0.0.0 dec-phase-iv
Router(config-ext-macl)# permit any any

ACL entries are scanned in the order you enter them. The first matching entry is used. To improve
performance, place the most commonly used entries near the beginning of the ACL.
An implicit deny any any entry exists at the end of an ACL unless you include an explicit permit
any any entry at the end of the list.
All new entries to an existing list are placed at the end of the list. You cannot add entries to the
middle of a list.

The PFC2 applies IP ACLs to ARP traffic.
The PFC3 does not apply IP ACLs to ARP traffic.
With a PFC3, you cannot apply microflow policing to ARP traffic.
