Configuring QoS
Beginning in privileged EXEC mode, follow these steps to create an aggregate policer:

After you have created an aggregate policer, you attach it to an ingress port. See the
Policy to an Interface" section on page
Cisco ME 3400 Ethernet Access Switch Software Configuration Guide

Purpose
Enter global configuration mode.
Define the policer parameters that can be applied to multiple traffic
classes within the same policy map.
•
For aggregate-policer-name, specify the name of the aggregate
policer.
•
For rate-bps, specify average traffic rate in bits per second
(bps). The range is 8000 to 1000000000.
•
For cir cir-bps, specify the committed information rate in bits
per second. The range is 8000 to 1000000000 bps.
•
(Optional) For bc burst-value, specify conform burst and the
number of acceptable burst bytes. The range is 8000 to 1000000
bytes.
•
(Optional) For conform-action, specify the action to take on
packets that conform to the CIR. The default is to send the
packet.
(Optional) For exceed-action, specify the action to take on
•
packets that exceed the CIR. The default is to drop the packet.
See the command reference for this release for definitions of the
available keywords.
Create a policy map by entering the policy map name, and enter
policy-map configuration mode.
Enter a class-map name and enter policy-map class configuration
mode.
Apply an aggregate policer to multiple classes in the same policy
map. For aggregate-policer-name, enter the name specified in
Step 2.
Return to policy-map configuration mode.
Return to global configuration mode.
Enter interface configuration mode for the interface to which you
want to attach the policy.
Attach the policy map (created in Step 3) to the ingress interface.
Return to privileged EXEC mode.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
