WLC advertising all configured WLAN's

Is there a way to stop the WLC advertising all the configured WLANS (SSID's) on every LWAPP AP? We have a WLC controlling several LAPs at different sites, but i only want the WLAN SSID's that are relevant to each site to be advertised on that AP. I know we can set the SSID to not be advertised, but the that is not ideal, as the SSID is still present. I have configured AP groups, so that each site will be assigned an IP address according to the dynamic interface mapped to the AP Group for that site. However even though each AP Group only contains 2 x WLAN's (1 for the A radio & 1 for the B/G radio) the AP still advertises all of the different WLAN's configured on the WLC. Is there a way of stopping this happening?

Re: WLC advertising all configured WLAN's

Hi Colin,

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;

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!
