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 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.
Syntax
