OMMAND INE
• 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.
Example
Console(config)#access-list mac mask-precedence in
