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 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.
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 that you use to re-enable the radio:
AP1242AG(config)# interface d1
AP1242AG(config-if)# shut
AP1242AG(config-if)# no mbssid
AP1242AG(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 in Some Regulatory Domains
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 to avoid interfering with them. You cannot manually set the
channel on DFS-enabled radios configured for these regulatory domains.

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.
TKIP and Cisco 7920 IP Phones
When a 7920 phone is associated to a 1250 series access point using Temporal Key Integrity Protocol
(TKIP) encryption, the access point might report “TKIP TSC replay detected” and discard the packets
transmitted by the phone (CSCsj35039). To work around this issue, perform one of the following:
(TKIP) encryption, the access point might report “TKIP TSC replay detected” and discard the packets
transmitted by the phone (CSCsj35039). To work around this issue, perform one of the following:
•
Use static or dynamic WEP with 802.1X key management for the 7920 SSID.
•
Disable long preambles.
