WLAN on a select group of APs

Unanswered Question
Sep 8th, 2008

Can I set up a WLAN with only a small group of many Access Points advertising it?

for example 20 APs advertise SSID-XXX and 4 of those 20 advertise SSID-YYY and SSID-XXX

I have this problem too.

Hi Scott,

The feature you are looking for is called WLAN Override :)

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;


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.

From this good doc;


Hope this helps!

Thanks for the info. I did see this in the docs and it makes sense. The issue is that I have 250 APs over 4 controllers. If I only want 20 APs to advertise a specific SSID, I have to create a WLAN and then use WLAN override on all 250 APs to turn it off on 230 and on on 20. I guess I could use an AP template on WCS to do this.

You will have to enable this on all ap's and also on both radios. You can use WCS to do this if you wish. It will save you a lot of time. :)
