broadcast of 2 SSID

Answered Question
Jun 10th, 2008

Hello,

on my access point 1240 , i have created two SSID.

I don't know if is possible to broadcast every SSID , because i can set only one with a guest mode.

CAN YOU HELP ME?

Thanks for your help

You should check these commands:

1. Global configuration mode

dot11 mbssid

This will enable multiple SSIDs support on all radio interfaces (for example, if you have an AP with 802.11g and 802.11a support)

2. Interface configuration mode

mbssid

To enable multiple SSIDs support just on the specific interface, for instance, just on the radio 802.11g but not on the 802.11a.

3. SSID configuration mode

mbssid guest-mode

To include the SSID on the beacons. Each SSID that you want to broadcast will need this command.

Hope this helps.

Hi Francesco,

This is possible;

Configuring Multiple Basic SSIDs

Access point 802.11a and 802.11g radios now support up to 8 basic SSIDs (BSSIDs), which are similar to MAC addresses. You use multiple BSSIDs to assign a unique DTIM setting for each SSID and to broadcast more than one SSID in beacons. A large DTIM value increases battery life for power-save client devices that use an SSID, and broadcasting multiple SSIDs makes your wireless LAN more accessible to guests.

--------------------------------------------------------------------------------

Note 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.

--------------------------------------------------------------------------------

Requirements for Configuring Multiple BSSIDs

To configure multiple BSSIDs, your access points must meet these minimum requirements:

•VLANs must be configured

•Access points must run Cisco IOS Release 12.3(4)JA or later

•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
