Solved: Compatability issues with Wireless Control system and Wireless Lan controllers

smith606306 · ‎03-17-2010

Hi,

We currently have a set up were we have 1 Wireless Controll System and 10 Wireless Lan Controllers installed on WISMs on Cisco Catalyst 6509s.

We are having a few issues the main one being with the Wlan Lan override facility corrupting SSIDs on various Access Points across our network.

The software versions we have Are:

WCS: 4.2.207.0

WLC: 5.0.56.2

IOS: 12.2

I have seen a Cisco document that states that these versions are not compatible for certain functions.

The document also leads us to believe that software versions WCS - 5.2.130.0 and WLC - 5.2.178.0 is a good stable version to have.

We would rather not upgrade the IOS on our switch at the moment if it can be helped.

Can anyone advise which are good stable versions to use and does anyone have any experience of migrating from Wlan override to AP groups.

Regards

Andrew

You should not need to worry about IOS levels. The 6509 code supports the WISM blade itself and is separate from the WLC code running for the LWAPP infrastructure.

Andrew,

The issue you are seeing more than likely is resulting from the WCS being of a lower level than the controllers. Everything the WCS tells the WLC to do is via SNMP and they changed alot from 4.2 to 5.2. To at least get this stable you should upgrade WCS to at least the latest 5.2 version which should resolve the issues.

I would recommend the manual upgrade procedure for WCS which is located here:

Apologies.

The WCS is 5.0.56.2

The WLc is 4.2.207.0

Ok that makes more sense then. I have seen many customers using the 5.2 combination with success and it definitely seems stable to me.

What about the IOS would that need updating too?

(IOS 12.2)

No. The WLC will manage the IOS of the LWAP.

Sorry I was talking about the IOS on the Cisco 6509s which is where the WISMs are installed
