In this first article, we will be talking about 802.11v.
Presentation of IEEE 802.11v
- L2 management of attached stations
- Monitoring the attached stations
- Configuring the attached stations
- Updating the attached stations
While the IEEE 802.11k amendment defined messages to retrieve information from the station, the ability to configure the station were not in its scope. So the 802.11v amendment is complementary to the 802.11k amendment.
If you want to learn more about 802.11v, please read the following documents from the IEEE:
Beacon of a Wi-Fi network NOT supporting 802.11v
Below is a look at a Beacon of a Wi-Fi network not supporting 802.11v. As you can see, the BSS Transition bit is set to "0".
Configuration of 802.11v on a Cisco WLC
- Navigate to the "WLAN" menu
- Select the WLAN profile you want to modify in order to open up the configuration view
- In the configuration view, select the "Advanced" tab
- Finally, in the advanced tab, under the "11v BSS Transition Support" section, select the "BSS Transition" option as shown in the image bellow:
