Configuring Multiple Basic Service Set Identifiers and Microsoft WPS IE SSIDL
This module describes how to configure multiple basic service set identifiers (BSSID) on a Cisco 800, 1800, 2800, or 3800 series integrated services router, hereafter referred to as an access point (AP).
Access point 802.11a and 802.11g radios support up to 16 BSSIDs which are similar to MAC addresses. You use multiple BSSIDs to broadcast more than one SSID in beacons.
Devices on your wireless LAN that are configured to associate to a specific access point based on the access point MAC address (for example, 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.
This module also describes how to configure the Microsoft WPS IE SSIDL feature. This feature allows an access point to broadcast a list of configured SSIDs such as SSID Lists (SSIDL) in the Microsoft Wireless Provisioning Services information element (WPS IE). A client with the ability to read the SSIDL can alert the user to the availability of the SSIDs.
Finding Feature Information in This Module

Prerequisites for Configuring Multiple Basic Service Set Identifiers and Microsoft WPS IE SSIDL
The following prerequisites apply to configuring multiple BSSIDs and Microsoft WPS IE SSIDL:
•VLANs must be configured.
•Access points must run Cisco IOS Release 12.4(15)T or a later release.
•Access points must contain an 802.11a or 802.11g radio that supports multiple BSSIDs. To determine whether a radio supports multiple basic SSIDs, enter the show controllers radio-interface command. The radio supports multiple basic SSIDs if the results include this line:
Number of supported simultaneous BSSID on radio-interface: 8

Before you configure QoS on an access point, you should understand the following concept:
•Guidelines for Using Multiple BSSIDs
Guidelines for Using Multiple BSSIDs
Remember these guidelines when configuring multiple BSSIDs:
•RADIUS-assigned VLANs are not supported when you enable multiple BSSIDs.
•When you enable BSSIDs, the access point automatically maps a BSSID to each SSID. You cannot manually map a BSSID to a specific SSID.
•When multiple BSSIDs are enabled on the access point, the SSIDL IE does not contain a list of SSIDs; it contains only extended capabilities.
•Any Wi-Fi certified client device can associate to an access point using multiple BSSIDs.
•You can enable multiple BSSIDs on access points that participate in WDS.
How to Configure Multiple BSSIDs and Include an SSID in an SSIDL IE

Configuring Multiple BSSIDs on an Access Point
Perform this task to configure multiple BSSIDs on an access point.

DETAILED STEPS
Including an SSID in an SSIDL IE
The access point or bridge beacon can advertise only one broadcast SSID. However, you can use SSIDL information elements (SSIDL IEs) in the access point or bridge beacon to alert client devices of additional SSIDs on the access point or bridge. When you designate an SSID to be included in an SSIDL IE, client devices detect that the SSID is available, and they also detect the security settings required to associate using that SSID.
SUMMARY STEPS
1. enable
2. configure terminal
3. dot11 ssid name
4. information-element ssidl [advertisement] [wps]
5. Repeat Steps 3 and 4 for each SSID you want included in the information element.
