Cisco Cisco Aironet 340 Ethernet Bridges

The bridge firmware menus and displays refer to Aironet Wireless Communications, Inc. Aironet is now 
part of Cisco Systems, Inc. Future versions of the firmware will be updated to reflect this change.

To prevent unauthorized wireless users from receiving data signals from the bridge, select off for the 
Allow Broadcast SSID setting. Follow these steps to make the selection:

On the computer connected to the bridge’s console port, select Configuration from the Main menu.

From the Configuration menu, select Radio.

From the Radio menu, select I80211.

From the I80211 menu, select Bcst_ssid to change the setting from on to off.

If the bridge is connected to the network, you can use an Internet browser to change the 
Allow Broadcast SSID setting. If you know the bridge’s IP address, type it in the browser’s 
address line and press Enter. At the Radio menu, click Allow Config Changes and click 
off for the Allow Broadcast SSID setting. If you don’t know the bridge’s IP address, point 
the browser to an Access Point and find the bridge in the Access Point’s association table. 
Click the bridge’s IP address to browse to the bridge.
