Important Notes
Some Devices Disassociate When Multiple BSSIDs Are Added or Deleted
Devices on your wireless LAN that are configured to associate to a specific access point based on the
access point MAC address (such as client devices, repeaters, hot standby units, or workgroup bridges)
might lose their association when you add or delete a multiple BSSID. When you add or delete a multiple
BSSID, check the association status of devices configured to associate to a specific access point. If
necessary, reconfigure the disassociated device to use the BSSID’s new MAC address.

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 and Singapore 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
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.
firmware version 1.09 or later.
Proxy Mobile-IP Feature Removed
The proxy Mobile-IP feature is not supported in Cisco IOS Releases 12.3(2)JA1 and 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.
