Command Mode
MAC Mask
Command Usage
• Up to seven masks can be assigned to an ingress or egress ACL.
• Packets crossing a port are checked against all the rules in the ACL until
a match is found. The order in which these packets are checked is
determined by the mask, and not the order in which the ACL rules were
entered.
• First create the required ACLs and inbound or outbound masks before
mapping an ACL to an interface.
Example
This example shows how to create an Ingress MAC ACL and bind it to a
port. You can then see that the order of the rules have been changed by the
mask.
