How can I verify CAPWAP/LWAPP access point?

[Totardo Tobing]

Hello,

I wonder how can I check / what command shoul I use on non-autonomous access points to see wether they are support capwap or they support lwapp??

Thank you folks..

The fastest way is to use the "sh verson" command. 

If your IOS has a filename like "K9W7" then it's autonomous.

Hello,

I think Leo means how to distinguish by autonomous and lightwieght. not between LWAPP and CAPWAP.

Autohomous APs have in their image nam: K9W7 while lightweight APs have K9W8. That is correct. But I think this is not the answer.

In order to distinguish if an AP uses LWAPP or CAPWAP you have first to know that:

- Some old APs support only LWAPP. They do not support CAPWAP (1010 and 1030 for example).

- CAPWAP started with WLC version 5.2. If you have 5.2 or later then your AP supports CAPWAP. (old APs metnioed above are not supported on 5.x. they are supported on up to 4.x).

- Some APs support CAPWAP only. They work onlyh on WLCs with version 5.2 and above that supports capwap. (1140 for example does not work with 4.x, 5.0 or 5.1). While some other APs may work with either lwapp or capwap (1240 works with lwapp if it joing WLC running 5.0 while it works with capwap if it joins WLC that runs 7.x).

Now, in order to know if your AP supports capwap or lwapp:

- You need to know if your AP has any limitation (if it is capwap only, lwapp only or can run on both).

- if your AP can run on both lwapp and capwap you can do follow the follownig steps:

* show version from the AP to know the IOS version running on it.

* Go to this link (wireless compatibility matrix): http://tiny.cc/k08thw

* in the page, look for your IOS versoin that you knew from show version command.

* find what is WLC version that your AP version corresponds to.

* If the corresponding WLC version is 5.2 or later then you are running CAPWAP. If your WLC runs 5.1 or earlier then      you are running lwapp.

On LWAPP only AP, capwap command don't exist bcoz lwapp only AP never join capwap wlc.

If you see commands like AP#lwapp, debug lwapp,... and not capwap commands like AP#capwap, test capwap, debug capwap then it is lwapp only AP.

Also, try this command AP#debug ip udp, if it tries only lwapp and no capwap then it is lwapp only AP. AP that supports capwap and lwapp does discovery on both capwap and lwapp. capwap only AP tries discovery using capwap only.

Thanks to you all guys. You all really helping.

I gues for me an easy-to-read answer is from Saravanan Lakshmanan. Pardon my brain but I really thanks you to you all.

Thank you
