Service Set Identifiers
Configuring Multiple Basic SSIDs
4
Cisco 3200 Series Wireless MIC Software Configuration Guide
•
Access points must contain a 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
Guidelines for Using Multiple BSSIDs
Keep these guidelines in mind 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 Service Set Identification List
information element (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.
CLI Configuration Example
This example shows the commands that you can use on the command-line interface (CLI) 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.
Use the
dot11 mbssid
command in global configuration mode to simultaneously enable multiple
BSSIDs on all radio interfaces that support multiple BSSIDs.
ap(config)# configure terminal
ap(config)# dot11 mbssid
ap(config)# dot11 ssid visitor
ap(config-ssid)# mbssid guest-mode dtim-period 75
ap(config-ssid)# exit
ap(config)# interface d0
ap(config-if)# ssid visitor
You can also use the
mbssid
command in configuration interface mode to enable multiple BSSIDs on an
access point radio interface. This example shows how to enable multiple BSSIDs on a radio interface:
ap(config)# interface d0
ap(config-if)# mbssid
ap(config-if)# exit
Displaying Configured BSSIDs
Use the
show dot11 bssid
command in privileged EXEC mode to display the relationship between
SSIDs and BSSIDs or MAC addresses. This example shows the command output:
AP1230# show dot11 bssid
Interface BSSID Guest SSID
Dot11Radio1 0011.2161.b7c0 Yes atlantic
Dot11Radio0 0005.9a3e.7c0f Yes WPA2-TLS-g
