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.
