MAC ACLS
The commands in this section configure ACLs based on hardware
addresses, packet format, and Ethernet type. The ACLs can further specify
optional IP and IPv6 addresses including protocol type and upper layer
ports. To configure MAC ACLs, first create an access list containing the
required permit or deny rules, and then bind the access list to one or more
ports.
