mask (MAC ACL)
This command defines a mask for MAC ACLs. This mask defines the fields to check
in the packet header. Use the
no form to remove a mask.
Syntax
[ no ] mask [ pktformat ]
{ any | host | source-bitmask } { any | host | destination-bitmask }
[ vid [ vid-bitmask ]] [ ethertype [ ethertype-bitmask ]]
• pktformat – Check the packet format field. (If this keyword must be used in
the mask, the packet format must be specified in ACL rule to match.)
• any – Any address will be matched.
• host – The address must be for a single node.
• source-bitmask – Source address of rule must match this bitmask.
• destination-bitmask – Destination address of rule must match this bitmask.
• vid – Check the VLAN ID field.
• vid-bitmask – VLAN ID of rule must match this bitmask.
• ethertype – Check the Ethernet type field.
• ethertype-bitmask – Ethernet type of rule must match this bitmask.

Command Mode
MAC Mask
Command Usage
• Up to seven masks can be assigned to an ingress or egress ACL.
• Packets crossing a port are checked against all the rules in the ACL until a
match is found. The order in which these packets are checked is determined
by the mask, and not the order in which the ACL rules were entered.
• First create the required ACLs and inbound or outbound masks before
mapping an ACL to an interface.
