Aironet Extensions IE (CCX IE)

Information About Aironet Extensions Information Element

The Cisco Aironet Extensions Information Element (IE) is an attribute used by Cisco devices for better connectivity. It contains information such as the AP name, device type, radio type, AP load, and the number of associated clients, in the beacon and probe responses of the WLAN. The Cisco Client Extensions use this information to associate with the best AP.

The Aironet Extensions IE configuration is disabled by default. With this feature you can set the AP name not through enabling the whole IE extension, but by just inserting just the AP name.

What to do next

  1. Create a policy tag. For more information about creating policy tags, refer to Configuring a Policy Tag (CLI).

  2. Map the policy tag to the AP. For more information about mapping a policy tag to the AP, refer to Attaching a Policy Tag and Site Tag to an AP (CLI).

Verifying the Addition of AP Name

The following example shows how to verify the addition of the AP Name (using Open Configuration) in the beacon without enabling IE:
