To disable OKC roaming on a WLAN SSID:
(Instant AP)(config)# wlan ssid-profile <name>
(Instant AP)(SSID Profile "<name>")# opmode {wpa2-aes|wpa-tkip,wpa-aes,wpa2-tkip,wpa2-aes}
(Instant AP)(SSID Profile "<name>")# okc-disable

Fast BSS Transition (802.11r Roaming)
802.11r is a roaming standard defined by IEEE. When enabled, 802.11r reduces roaming delay by pre-
authenticating clients with multiple target IAPs before a client roams to an IAP. With 802.11r implementation,
clients pre-authenticate with multiple IAPs in a cluster.
As part of the 802.11r implementation, Instant 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.
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 IAP for 802.11r support
You can configure 802.11r support for a WLAN SSID by using the Instant UI or the CLI.
In the Instant 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:
(Instant AP)(config)# wlan ssid-profile <name>
(Instant AP)(SSID Profile <name>)# dot11r
(Instant AP)(config)# end
(Instant AP)# commit apply
Example
(Instant AP)(config)# wlan ssid-profile dot11r-profile
(Instant AP)(SSID Profile "dot11r-profile")# dot11r
(Instant AP)(config)# end
(Instant AP)# commit apply
