permit, deny (MAC ACL) This command adds a rule to a MAC ACL. The rule filters packets matching a
specified MAC source or destination address (i.e., physical layer address), or
Ethernet protocol type. Rules can also filter packets based on IPv4/v6 addresses,
including Layer 4 ports and protocol types. Use the no form to remove a rule.
