SSID Broadcast issue

Unanswered Question

Here is my scenario:

We have an arena environment where 32 AP's broadcast 2 SSID's (ssid-A, and ssid-b). I want to prevent wireless clients from associating to 2 of my AP's ssid-A, I just want to broadcast and have clients associate to ssid-B, so my question is, if I remove ssid-A from broadcasting on those 2 AP's will that prevent those clients from associating to it?

Hi Rene,


Not broadcasting the SSID will not prevent clients for connecting if they know the SSID Name etc. If you are using the WLC LWAPP configuration you can use WLAN Override to clip this SSID from the 2 AP's.


Enabling WLAN Override


By default, access points transmit all defined WLANs on the controller. However, you can use the WLAN Override option to select which WLANs are transmitted and which ones are not on a per access point basis. For example, you can use WLAN override to control where in the network the guest WLAN is transmitted or you can use it to disable a specific WLAN in a certain area of the network.


From this doc;


http://www.cisco.com/en/US/products/ps6366/products_configuration_guide_chapter09186a008076cbfd.html#wp1114777


Once you create a new WLAN, the WLAN > Edit page for the new WLAN appears. In this page you can define various parameters specific to this WLAN including General Policies, RADIUS Servers, Security Policies, and 802.1x Parameters.


**Check Admin Status under General Policies to enable the WLAN. If you want the AP to broadcast the SSID in its beacon frames, check Broadcast SSID.


Note: You can configure up to sixteen WLANs on the controller. The Cisco WLAN Solution can control up to sixteen WLANs for Lightweight APs. Each WLAN has a separate WLAN ID (1 through 16), a separate WLAN SSID (WLAN name), and can be assigned unique security policies. Lightweight APs broadcast all active Cisco WLAN Solution WLAN SSIDs and enforce the policies that you define for each WLAN.

Hope this helps!

Awesome. Great information, I have followed your directions, being that we do have LWAPP, and applied it to my AP's. This will help greatly, a million thanks!
