MAC ACLs
The commands in this section configure ACLs based on hardware addresses, packet
format, and Ethernet type. 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.
access-list mac This command adds a MAC access list and enters MAC ACL configuration mode.
Rules can be added to filter packets matching a specified MAC source or
destination address (i.e., physical layer address), or Ethernet protocol type. Use the
no form to remove the specified ACL.
