Universal Workgroup Bridge Limitations

The following limitations and restrictions apply to universal workgroup bridges:
• A universal workgroup bridge cannot associate with the Cisco WLAN AP when the bridge is
configured with CKIP or CMIC encryption.
• If the universal workgroup bridge is associated with a Cisco AP or third-party AP and if the user
issues the show dot11 association all command, the IP address and name information is not
available.
• Users should configure the static IP address on the Bridge-Group Virtual Interface (BVI) when it is
in the universal workgroup bridge mode, so that the WMIC is manageable from the MAR through
the Mobile IP tunnel from the infrastructure side.
• If the dynamic Collocated Care-of Address (CCoA) is used on the Cisco 3200 Series Wireless and
Mobile Router, you should configure the static IP address using the ip secondary address
command.
• The universal workgroup bridge is not compatible with the Tropos version 3.1.1.2 AP.
• A universal workgroup bridge cannot associate with the Cisco 1500 router when it is configured with
the Allow WPA2 TKIP Clients option.
