Configuring Fast Roaming for Wireless Clients
11.2.1
Opportunistic Key Caching
SCALANCE W now supports opportunistic key caching (OKC)-based roaming. In OKC-
based roaming, the AP stores one pairwise master key (PMK) per client, which is derived
from the last 802.1X authentication completed by the client in the network. The cached PMK
is used when a client roams to a new AP. This allows faster roaming of clients between the
APs in a cluster, without requiring a complete 802.1X authentication.
Note
OKC roaming (when configured in the 802.1X Authentication profile) is supported on WPA
-2
clients. If the wireless client (the 802.1X supplicant) does not support this feature, a complete
802.1X authentication is required
whenever a client roams to a new AP
Configuring an AP for OKC Roaming
You can enable OKC roaming for 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.
