Important Notes
Enabling MBSSIDs Without VLANs Disables Radio Interface
If you use the mbssid configuration interface command to enable multiple BSSIDs on a specific radio
interface but VLANs are not configured on the access point, the access point disables the radio interface.
To re-enable the radio, you must shut down the radio, disable multiple BSSIDs, and re-enable the radio.
This example shows the commands you use to re-enable the radio:
interface but VLANs are not configured on the access point, the access point disables the radio interface.
To re-enable the radio, you must shut down the radio, disable multiple BSSIDs, and re-enable the radio.
This example shows the commands you use to re-enable the radio:
AP1134(config)# interface d1
AP1134(config-if)# shut
AP1134(config-if)# no mbssid
AP1134(config-if)# no shut
After you re-enable the radio, you can enable VLANs on the access point and enable multiple BSSIDs.
Cannot Set Channel on DFS-Enabled Radios
Access points with 5-GHz radios configured at the factory for use in Europe, Singapore, Korea, Japan,
Taiwan, and Israel now comply with regulations that require radio devices to use Dynamic Frequency
Selection (DFS) to detect radar signals and avoid interfering with them.You cannot manually set the
channel on DFS-enabled radios.

Cisco 7920 Phones Require Firmware Version 1.09 or Later When Multiple
BSSIDs Are Enabled

When multiple BSSIDs are configured on the access point, Cisco 7920 wireless IP phones must run
firmware version 1.09 or later.

AIR-RM21A/AIR-RM22A Radio Modules Usually Set to Max Transmit Power
AIR-RM21A and AIR-RM22A radio modules measure transmit power in decibels per milliwatt (dBm),
but earlier versions of 802.11a radios in Cisco Aironet access points measure power in milliwatts (mW).
Because power settings in mW do not translate directly to settings in dBm, the access point usually uses
the default power setting of maximum when you install a new AIR-RM21A or AIR-RM22A radio
module.
