Chapter 20 Configuring ACLs
Configuring MAC ACLs
To remove a MAC ACL, perform this task:
Changing Sequence Numbers in a MAC ACL
You can change all the sequence numbers assigned to rules in a MAC ACL. Resequencing is useful when
you need to insert rules into an ACL and there are not enough available sequence numbers. For more
information, see the
“Rules” section on page 20-2 .
To change all the sequence numbers assigned to rules in a MAC ACL, perform this task:
Applying a MAC ACL as a Port ACL
You can apply a MAC ACL as a port ACL to any of the following interface types:
• Layer 2 interfaces
•
Port-channel interfaces
Be sure that the ACL that you want to apply exists and is configured to filter traffic as necessary for this
application. For more information about configuring MAC ACLs, see the
“Configuring IP ACLs”
section on page 20-4 .

larger than the preceding rule. The difference in
numbers is determined by the increment number
that you specify.
