subsets of ssid on LWAP on same controller

I was wondering if it is possible to determine which SSID's are available on a group of LWAP. If I want a special SSID to only appear in a certain small group of LWAP (say a single building), but there are many more LWAP on the same WLC that I dont want that SSID to appear on. I only seem able to put enable or disable an SSID across all LWAP.

I have a WiSM, 90x 1130AG, and WCS. Each SSID is it's own VLAN.

Regards.

Re: subsets of ssid on LWAP on same controller

Hi Mike,

That is very well possible using a feature called as WLAN Override. Which you can enable on respective AP radios and then check on which ssid this AP radio should advertise.

This link should help you with the same

Hi Mike,

Ankur is most correct here (5 points for this Ankur and nice to see you back here posting great answers!)

I just wanted to add a little more reference material;

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.

From this good doc;

http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a0080665d18.shtml#c3

The most popular way to mitigate the problem of having to access each AP individually (when using WLAN Override) is to use WCS Templates for common requirement AP's. This way the WLAN Override function can be applied at the Template level and then pushed out to the various groups.

Hope this helps!
