Configuring Fast Layer 2 Roaming for
WPA/WPA2 with 802.1X
Fast roaming facilitates roaming in a WLAN that requires WPA/WPA2 with 802.1X
authentication. That is, it speeds the process of a station connecting to a new RP and
possibly a new Wireless Edge Services zl Module:
■ putting necessary encryption keys in place
■ when necessary, completing 802.1X authentication
If your network includes only one Wireless Edge Services zl Module or if your
network requires roaming only between RPs adopted by the same module, you do
not need to configure fast Layer 2 roaming. The module supports it by default.
However, in a network in which stations might need to roam between RPs adopted
by different modules, you must enable fast roaming for WLANs that enforce WPA
with 802.1X authentication. Follow these steps:
1. Select Network Setup > WLAN Setup > Configuration.
2. Select the WLAN on which you want to enable fast roaming.
3. Click the Edit button.
4. Configure the WLAN settings, making sure to select 802.1X EAP for authentica-
tion and WPA/WPA2-TKIP or WPA2-AES for encryption.
For more information about configuring WLANs, see Chapter 4: “Wireless
Local Area Networks (WLANs).”
