Objective

A Policy Map executes the action when a condition is matched in the Class Map. Class Maps contain conditions that traffic need to match in order to be forwarded or dropped. There can be many Class Maps in a Policy Map where either one Class Map can be matched, or all Class Maps should be matched for the action specified in the Policy Map to take place. A Class Map and a Policy Map are created to complete the Quality of Service (QoS) configuration on an access point. For instructions on how to configure QoS, click here. For instructions on how to create a Class Map, click here.

This article aims to show you how to create a Policy Map on a wireless access point.

Note: A Policy Map cannot be created if there is no Class Map.

Add and Configure a Policy Map

Step 1. Log in to the access point web-based utility and choose Client QoS > Policy Map.

Note: If there are no configured Policy Maps yet, only the Policy Map Configuration area will be displayed.

Step 2. In the Policy Map Name field, enter the name for the Policy Map you need to create. The name can be 1 to 31 alphanumeric characters and special characters, without spaces.

Note: In this example, the name is Policy_Map_1.

Step 3. Click Add Policy Map.

Step 4. In the Policy Class Definition area, choose the Policy Map you need to configure from the Policy Map Name drop-down menu.

Note: In this example, Policy_Map_1 is chosen.

Step 5. Choose the Class Map to be applied to the Policy Map from the Class Map Name drop-down menu.

Note: In this example, Class_Map_1 is chosen.

Step 6. Click a Police Simple radio button. This feature establishes the traffic policing style for the class. The simple form of the policing style uses a single data rate and burst size, resulting in two outcomes: conform and nonconform. The options are:

- Any — This option does not set any parameter to which traffic must conform. This is the default setting.

- Committed Rate — This option allows you to specify a committed rate in Kbps, and a committed burst, in bytes, to which traffic must conform. Committed Rate can be from 1 to 1000000 Kbps. Committed Burst is from 1 to 204800000 bytes.

Note: In this example, Any is chosen.

Step 7. Based on the Police Simple setting, choose settings for the Policy Match Attribute. The options are:

- Send — This option specifies that all packets for the associated traffic stream are to be forwarded if the Class Map criteria is met.

- Drop — This option specifies that all packets for the associated traffic stream are to be dropped if the Class Map criteria is met.

- Mark Class Of Service — This option marks all packets for the associated traffic stream with the specified class of service (CoS) value in the priority field of the 802.1p header. If the packet does not already contain this header, one is inserted. The CoS value should be an integer from 0 to 7.

- Mark IP DSCP — This option marks all packets for the associated traffic stream with the IP DSCP value that you select from the list.

- Mark IP Precedence — This option marks all packets for the associated traffic stream with the specified IP precedence value. The IP precedence value is an integer from 0 to 7.

Note: In this example, Drop is chosen. Meaning, packets that match the condition specified in Class_Map_1 will be dropped, as suggested by this configuration.

Step 8. (Optional) Check the Disassociate Class Map check box to remove the class chosen in the Class Map Name list from the policy chosen in the Policy Map Name list.

Note: The Member Classesarea displays all DiffServ Classes currently associated with the selected policy. If no classes are currently associated, the area is blank.

Step 9. (Optional) To delete the current policy, check the Delete Policy Map check box.

Step 10. Click Save to save the changes to the startup configuration.

You should now have successfully configured a Policy Map on your Wireless Access Point (WAP).
