MAC ACL

24-21

Command Usage

• You must configure a mask for an ACL rule before you can bind it to

a port or set the queue or frame priorities associated with the rule.

• A mask can only be used by all ingress ACLs or all egress ACLs.

• The precedence of the ACL rules applied to a packet is not determined

by order of the rules, but instead by the order of the masks; i.e., the

first mask that matches a rule will determine the rule that is applied to

a packet.
