Viewing Wlan Statistics - Motorola WiNG 4.4 Reference Manual

4 - 58 WiNG 4.4 Switch System Reference Guide
NOTE: Legacy MUs supporting WEP encryption and new MUs supporting 802.11i WPA/WPA2-TKIP encryption can not
co-exist on the same WLAN. The multi-cipher support feature allows you to enable these two device types to co-exist
on the same WLAN.
This feature allows using a combination of WEP encryption and 802.11i encryption on a per WLAN basis. This is done by
creating WLANs with the same SSID but with different BSSIDs and security cipher combinations. The APs broadcast
different beacons for the same SSID. The MUs associate with the AP based on its configuration of SSID, BSSID, and
security cipher.
This feature supports the following combinations of security ciphers:
• WEP 64 and WPA/WPA2-TKIP
• WEP 64 and WPA-CCPMP
• WEP 128 and WPA/WPA2-TKIP
• WEP 128 and WPA-CCMP
• WPA-CCMP and WPA/WPA2-TKIP
These security cipher combinations are available on a per WLAN basis.
The following are the limitations of this feature:
• You should make sure that the WLANs created with the same SSIDs are grouped into different WLAN groups. This is
because WLANs with common SSID should have unique BSSIDs.
• WEP 64 and TKIP/CCMP ciphers can not be part of the same WLAN group.
• When WEP 128/TKIP and CCMP ciphers are grouped in the same WLAN group, the BC/MC encryption is downgraded
to WEP 128/TKIP. So in scenarios where 'N only' MUs are present they may not able to associate as those MUs do not
support WEP 128/TKIP. In such cases WLANs with WEP 128/TKIP cipher suites should be in a different WLAN group
than those WLANs with CCMP cipher suites.
• When downgrading the firmware on the AP, WLANs with same SSIDs are not supported by the old version of the
firmware image and hence there could be errors while configuring the AP after booting up with image. Only the first
WLAN with the common SSID may get created.
• When exporting the configuration to an AP, which does not support this feature there could be errors while configuring
the AP. Only the first WLAN with the common SSID may get created.

4.5.2 Viewing WLAN Statistics

The Statistics screen displays read-only statistics for each WLAN. Use this information to assess if configuration changes
are required to improve network performance. If a more detailed set of WLAN statistics is required, select a WLAN from
