4-140
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.
