Chapter 3 Configuring Multiple SSIDs
Enabling MBSSID and SSIDL at the same time
• 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 c an e na b le m ul ti ple BS SID s on a cc es s poi nts th at p ar tic ipa te i n W DS .
CLI Configuration Example
This example shows the CLI commands that you use to enable multiple BSSIDs on a radio interface,
create an SSID called visitor, designate the SSID as a BSSID, specify that the BSSID is included in
beacons, set a DTIM period for the BSSID, and assign the SSID visitor to the radio interface:
router(config)# interface dot11 0
router(config-if)# mbssid
router(config-if)# exit
router(config)# dot11 ssid visitor
router(config-ssid)# mbssid guest-mode
router(config-ssid)# exit
router(config)# interface dot11 0
router(config-if)# ssid visitor
You c an a ls o u se th e dot11 mbssid global configuration command to simultaneously enable multiple
BSSIDs on all radio interfaces that support multiple BSSIDs.
Displaying Configured BSSIDs
Use the show dot11 bssid privileged EXEC command to display the relationship between SSIDs and
BSSIDs or MAC addresses. This example shows the command output:
router1230#show dot11 bssid
Interface BSSID Guest SSID
Dot11Radio1 0011.2161.b7c0 Yes atlantic
Dot11Radio0 0005.9a3e.7c0f Yes WPA2-TLS-g
Enabling MBSSID and SSIDL at the same time
When multiple BSSIDs are enabled on the access point, the SSIDL IE does not contain a list of SSIDs;
it contains only extended capabilities.
Beginning in privileged EXEC mode, follow these steps to include an SSID in an SSIDL IE:
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface dot11radio { 0 | 1 } Enter interface configuration mode for the radio interface.
Step 3
ssid ssid-string Enter configuration mode for a specific SSID.
Step 4
information-element ssidl
[advertisement] [wps]
Include an SSIDL IE in the access point beacon that advertises
the access point’s extended capabilities, such as 802.1x and
support for Microsoft Wireless Provisioning Services (WPS).
Use the advertisement option to include the SSID name and
capabilities in the SSIDL IE. Use the wps option to set the WPS
capability flag in the SSIDL IE.
