access-list mac mask-precedence

This command changes to MAC Mask mode used to configure access
control masks. Use the no form to delete the mask table.
Syntax
[no] access-list ip mask-precedence {in | out}
in – Ingress mask for ingress ACLs.
out – Egress mask for egress ACLs.
Default Setting
Default system mask: Filter inbound packets according to specified
MAC ACLs.
Command Mode
Global Configuration
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.
