Syntax
[no] access-list ip mask-precedence {in | out}

Command Usage
• 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.
• 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.
