4404 multi-story building

Unanswered Question
Mar 17th, 2008

How do you configure the 4404 so that only one ssid is sent to one floor? IE... SSID - 4th_Floor is sent to the AP's only on the 4th floor?

I have this problem too.

Hi Robert,

Very good question :) 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!

Rob, as always, lots of excellent info! 5 pts to you.

Another aspect to add is the use of directional antennae to mitigate signals from bleeding from one floor to the next as well as tuning power levels on the APs
