Cisco Cisco Aironet 1200 Access Point

This section lists new features in Cisco IOS Release 12.3(4)JA. 

 lists the features that are 

supported on the devices that support this release. 

This feature permits a single access point to appear to the WLAN as multiple virtual access points.  It 
does this by assigning an access point with multiple Basic Service Set IDs (MBSSIDs) or MAC 
addresses.

To determine whether a radio supports multiple basic SSIDs, enter the show controllers command for 
the radio interface. The radio supports multiple basic SSIDs if the results include this line:

Number of supported simultaneous BSSID on radio_interface: 8 

This feature allows Cisco access points configured at the factory for use in Europe and Singapore to 
detect radar signals such as military and weather sources and switch channels on the access points.

This feature provides scanner access points the ability to detect that WLAN management and control 
frames exceeded a configurable threshold.
