Configuring WLANs
Configuring Multiple WLANs with the Same SSID
In release 4.0.206.0 and greater, you can configure multiple WLANs with the same SSID. This feature
enables you to assign different Layer 2 security policies within the same wireless LAN. To distinguish
among WLANs with the same SSID, you must create a unique profile name for each WLAN.
These restrictions apply when configuring multiple WLANs with the same SSID:
•
WLANs with the same SSID must have unique Layer 2 security policies so that clients can make a
WLAN selection based on information advertised in beacon and probe response. These are the
available Layer 2 security policies:
–
None (open WLAN)
–
Static WEP or 802.1X
Note
Because static WEP and 802.1X are both advertised by the same bit in beacon and probe
responses, they cannot be differentiated by clients. Therefore, they cannot both be used
by multiple WLANs with the same SSID.
–
CKIP
–
WPA/WPA2
Note
Although WPA and WPA2 cannot both be used by multiple WLANs with the same
SSID, two WLANs with the same SSID could be configured with WPA/TKIP with PSK
and WPA/TKIP with 802.1X, respectively, or with WPA/TKIP with 802.1X or
WPA/AES with 802.1X, respectively.
•
Hybrid-REAP access points do not support multiple SSIDs.
Additions to the Controller GUI
The new Profile Name parameter appears on three controller GUI pages:

The
WLANs
page, which lists all WLANs configured on the controller.
Figure 6-13
shows two
SSIDs named “abc” but with different profile names (abc1 and abc2). Notice that their security
policies are also different.
