Configuring Multiple Basic SSIDs
(Optional) In the Multiple BSSID Beacon Settings section, select the Set SSID as Guest Mode check
Step 7
box to include the SSID in beacons.
Step 8 (Optional) To increase the battery life for power-save clients that use this SSID, select the Set Data
Beacon Rate (DTIM) check box and enter a beacon rate for the SSID. The beacon rate determines how
often the access point sends a beacon containing a Delivery Traffic Indicator Message (DTIM).
When client devices receive a beacon that contains a DTIM, they normally wake up to check for pending
packets. Longer intervals between DTIMs let clients sleep longer and preserve power. Conversely,
shorter DTIM periods reduce the delay in receiving packets but use more battery power because clients
wake up more often.
The default beacon rate is 2, which means that every other beacon contains a DTIM. Enter a beacon rate
between 1 and 100.
Increasing the DTIM period count delays the delivery of multicast packets. Because multicast packets
Note
are buffered, large DTIM period counts can cause a buffer overflow.
Step 9 In the Guest Mode/Infrastructure SSID Settings section, select Multiple BSSID.
Step 10 Click Apply.

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:
ap(config)# interface d0
ap(config-if)# mbssid
ap(config-if)# exit
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 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:
AP1230#show dot11 bssid
Interface

Dot11Radio0
