Fast BSS Transition (802.11r Roaming)
02.11r is a roaming standard defined by IEEE. When enabled, 802.11r reduces roaming
delay by pre- authenticating clients with multiple target APs before a client roams to an AP.
With 802.11r implementation, clients pre-authenticate with multiple APs in a cluster.
As part of the 802.11r implementation, SCALANCE W supports the Fast BSS Transition
protocol. The Fast BSS Transition mechanism reduces client roaming delay when a client
transitions from one BSS to another within the same cluster. This minimizes the time
required to resume data connectivity when a BSS transition happens.
Note
Fast BSS Transition is operational only if the wireless client supports 802.11r standard. If the
client does not support 802.11r standard, it falls back to the normal WPA
-2 authentication
method.
Configuring an AP for 802.11r support
You can configure 802.11r support for a WLAN SSID by using the SCALANCE W UI or the
CLI.
In the SCALANCE W UI
1. Navigate to the WLAN wizard (Go to
Network > New
OR Go to
Network > WLAN SSID
and click
edit
).
2. Click the
Security
tab.
3. Under
Fast Roaming
, select the
802.11r
check box.
4. Click
Next
and then click
Finish
.
In the CLI
To enable 802.11r roaming on a WLAN SSID:
(scalance)(config)# wlan ssid-profile <name>
(scalance)(SSID Profile <name>)# dot11r
(scalance)(config)# end
(scalance)# commit apply
