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.
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. Rules can also be used
to filter packets based on IPv4/v6 addresses, including Layer 4 ports and
protocol types. Use the no form to remove the specified ACL.
