802.11n doesn’t work for WLAN created using WCS templates

s.jayaram

But works when enabled on the controller

WLC 5508 - 7.0.116.0

WCS - running firmware 7.0.172.0

Clean Air AP used  for testing -LAP 3500

Anyone aware of this issue?

Thanks

Why not... In order to enable 802.11n you need the following:

Open authentication or WPA2/AES

WMM policy is allowed

So if you push out a template and for example it sets WMM to disabled, well your users will only connect at 802.11b/g.

I don't think it is your templates at all. If your creating a new ssid an you want to push it to many WLC's, then use WCS. If you have one or two WLC's then just create it manually.

What feature or part of the WLAN template does not work when you push out a template. All you really need on a WLAN SSID template for 802.11n is WMM enabled in the WLAN and the use of open authentication or WPA2/AES.

After you push out a template or creating or editing an ssid, are you saying you have to manually edit the WLAN setting on the wlc to enable one of these features?

Yes that is correct, they have lots of 802.11n cleints. No voice or video is currently deployed

Any WLAN’s that we configured using templates from WCS don’t offer 802.11n, you can only connect at a/b/g with max 54mbps. When I configure the WLAN on the WLC itself 802.11n works instantly.

Can you share your template . i.e how you are pushing the template and a snapshot.

Attached is a screenshot from the template

Under the Security tab, you need to either use open authentication or wpa2/aes.  On the QoS tab, you need to specify WMM Policy Allowed.  Make sure your clients do have 802.11n cards.  Also in your WLC, under your 802.11a, make sure you set your channel width to 40mhz.

But Scott, they use  EAP-TLS  for Client Access, Does Cisco recommend to push the secuirty policy from the controller  and not WCS

Thanks

Why would it be different whether you push the policy to couple or many Controllers, WCS should be able to work this out correctly??

Right now thay have only three controllers, But this is going to change in few months, I will try this with customer tomorrow and let you know.

Thanks for your time

When you test tomorrow, please configure the whole template including the security, QoS and the advanced tab. WCS doesn't control how users connect. It's better if you can test yourself and see what your client is actually getting.

Yes it worked !!! Thank you both  for your time.

I deleted all WLANs created by client on the WLC and pushed new policy from WCS , test it few times.

Until next time

Hi,

Thanks for sharing that template.. Now can you take a snapshot of Security and QOS and Advanced tab.

ON WCS by default wmm = disabled and on WLC it is enabled by default.

Check 802.11n to see what needs to be enabled to get it to work.
