This example shows how to create a Layer 2 MAC ACL with two permit statements and attach it to an
ingress port. The first permit statement allows traffic from the host with MAC address 0001.0000.0001
destined for the host with MAC address 0002.0000.0001. The second permit statement allows only
Ethertype XNS-IDP traffic from the host with MAC address 0001.0000.0002 destined for the host with
MAC address 0002.0000.0002.

Classifying, Policing, and Marking Traffic by Using Aggregate Policers

By using an aggregate policer, you can create a policer that is shared by multiple traffic classes within
the same policy map. However, you cannot use the aggregate policer across different policy maps or
ports.
The 10-Gigabit interfaces do not support policing by using an aggregate policer.
