Convert capwap to LWAPP telnet

Is it possible to convert capwap to LWAPP via telnet?
Through the 5508 controller, I enabled Telnet for a specific AP with capwap image.
I was able to telnet to the AP and access CLI.
I issued the command capwap ap controller ip address x.x.x.x
The AP did not reject the command with an error, but it did not accept the command either. Is there anyway I can do this remotely? Do I need to gather the AP's and console in?

Yes, CAPWAP is the IEEE standard (not proprietary like LWAPP which is cisco proprietary) for AP to WLC communication.
If AP is managed via controller (WLC) then we referred as Lightweight (or unified wireless). If it operate standalone without a controller then it is referred as "Autonomous". You can convert an AP from Autonomous to Lightweight (& vise versa)
In your case since you want to manage it through WLC (which is the best way of deploying wireless), you do not want to worry about these encapsulation method too much.
If you are new then I would suggest you to read about basic topics like AP registraion/CAPWAP. Here are some links from my blog which may help you on this

CAPWAP vs LWAPP

Hello all. I have WLC 4402 and Aironet 1522 AP's. Implementation includes mesh topology and ethernet bridging. I have configured LWAPP L2 in the very beginning. But then I have read that for ethernet bridging LWAPP L3 must be configured. Till now mesh is working fine, but AP that provides ethernet bridging some times goes down. Few minutes ago I have found this http://www.cisco.com/en/US/docs/wireless/technology/mesh/design/guide/MeshAP_52.html#wp1167834 where it says that in release 5.2 (and that release is on my WLC) CAPWAP replaces LWAPP.
So, what should I do?
Should I configure for ethernet bridging LWAPP L3 or what?
Thanks in advance!

Although CAPWAP is based on LWAPP there are some critical differences to note. First, control traffic is no longer contained in a AES encrpted LWAPP tunnel and data traffic in the clear. On a WLC 4400 data traffic is still in the clear and control traffic is in a DTLS encrypted tunnel. In the upcoming controllers it is proposed to enhance security by including ALL traffic in the DTLS tunnel. Second, the CAPWAP discovery process is much more robust than LWAPP. Third, dynamic MTU is part of CAPWAP. This allows for better communication between the controller and the network. This was a big issue with LWAPP and a much needed improvement.
Layer 3 is the ONLY method I would deploy in either LWAPP or CAPWAP as it truly enables the functionality of IP. I was a big proponent early on of Layer 2 for small offices but as IP Voice communications and applications continued to develope, the need for Layer 3 in all deployments became more evident. This became Cisco's plan as well and layer 2 is considered a out of date legacy method of configuring a WLAN.

Upgrade/convert 521 to LWAPP

I have a 526 controller and 4 521 APs on my LAN that I want to upgrade to LWAPP. I am using CCA and all the help says this should be a point-and-click type of thing. However, when I try the upgrade the CCA asks for an image I don't have and can't find in the CCA folder. The download section for the 521 doesn't have it either. Where can I get this image? Is there another way to upgrade?
Thanks in advance,
Diego

I have the right recovery code but the CCA topology map doesn't even see any of my 521 AP's. It can see the WLC526 and it can see the 3560 PoE switch it's attached to, but those are the only 2 items on the topology map. I'm using native VLAN as 100. I set the ports the 521's into a trunk ports w/ native vlan as 100 so I can http to the 521 AP's. I'm using 3 vlans, voice, guest, and internal users but I just can't get them to join the WLC as LWAPPS??? Frustrating!! Any ideas? All the documentation shows the AP's showing in the topology map and then you just point/click to LWAPP recovery image to convert them from autonmouse to LWAPP but I can't even see them in the topology map yet I can ping and web to them and they seem fine. I could probably leave them all autonomous and manually configure all 5 and have it work anyways but I'd be waisting the WLC 526 and it would serve no purpose?!?!?!
Thanks!!!

Converting ap1250 to Lwapp

Hello, I am having issues trying to convert from autonomous to lwapp. This is the first time working with this model, we have 1242's which are lwapp and working fine. The version I have is 12.4(10b).JA1 but when I use the upgrade tool and try to use image file c1250-rcvk9w8-tar.124-10b.JA1.tar I get an error stating that the LWAPP Recovery Image is not a valid one. I got this file from Cisco and I am very confused as to why this does not work. Anything I am missing? Thanks!

Requirements:
â¢ Image file (The recovery file has the prefix ârcvâ in the image name, such as c1200-rcvk9w7-tar.122-15.JA.tar);
â¢ AP is connected to the Wireless LAN Controller; and
â¢ AP can ping the TFTP server where the image is located.
Procedure
1. Copy the recovery file to the AP using the following command:
archive tar /x tftp:/// flash:
2. Let the AP boot on this image:
boot system flash://.bin
3. Reboot the AP.
OPTIONAL
â¢ DO NOT ALLOW THE AP TO JOIN THE WIRELESS LAN CONTROLLER IN ORDER TO USE THE OPTIONAL COMMANDS BELOW.
â¢ IF POSSIBLE, type the following commands:
ï¾ clear lwapp private-config (This will bring the AP to factory default.);
ï¾ clear lwapp ap ip address
ï¾ clear lwapp ap hostname
ï¾ clear lwapp ap controller ip address
4. Let the AP connect to the Wireless LAN controller.
OPTIONAL
If an AP refuses to join the Wireless LAN Controller, type the following command from the AP:
lwapp ap controller ip address

Convert AP to LWAPP

Hi,
We recently purchased a few more 1131 APs for a remote office. For some reason, only one came as LWAPP AP, and the rests are all Autonomous APs.
I have successfully upgraded one Auto AP into LWAPP, it is under control of that office's WLC.
The image I downloaded is the latest one : c1130-rcvk9w8-tar.124-10b.JA3.tar, I am not too sure if I should have used c1130-rcvk9w8-tar.123-11JX1.tar
However i noticed that the product ID still shows up as AIR-AP1131AG-E-K9 instead of AIR-LAP1131AG-E-K9 like the one came with LWAPP. How to fix this, is this matters. Any help will be highly appreciated.

The image you used is fine for the conversion. The AP will use the code it gets from the controller anyway, so you don't need to worry there.
And sorry, but the product ID never changes. The AP was an AP when it was produced, and it will forever remain an AP. It cannot become an LAP, at least as far as the product ID is concerned.

Problems converting 1242AP from LWAPP to Autonomous

I tried to downgrade a 1242 LAP to Autonomous through a WLC using cisco's brief instructions:
Step 1 Log into the CLI on the controller to which the access point is associated.
Step 2 Enter this command:
config ap tftp-downgrade tftp-server-ip-address filename access-point-name
Seems easy enough, i copied the IOS file (c1240-k9w7-tar.123-7.JA5.tar) to my TFTP root. Then i ran the command mentioned above from the CLI of the WLC. The WLC takes the command but nothing happens, if i hold down mode and reboot the AP it retains its previous settings? Any ideas?

In the end i ended up using the a version of the IOS that was one iteration older and it worked......bizzare

How to convert AIR-AP1041N (autonomus) to AIR-LAP1041N (lwapp)

Hi,
some days ago I succesfully converted AIR-LAP1041N (lwapp) to AIR-AP1041N (autonomus).
I used c1140-k9w7-tar.124-25d.JA1.tar which is available to download in Download Software Section for this AP.
But there are any autonomus to lightweigt firmware for this AP.
I tried to use c1140-rcvk9w8-tar.124-21a.JA2.tar for 1140 but AP hungs after that.
How can i back to LWAPP version in 1041?

this is what can i see on the console:

but i connected this AP to dhcp server i see that AP recived IP address from DHCP i tries to search conntroller (i can see frames from AP in wireshark, req to DHCP for CISCO-CAPWAP-CONTROLLER).
so in next days i will try to connect AP to the controller (wlc is in different site, without vpn connectivity).
i think that AP is bad, because of this "weirid chars" on console, but maybe when ap updates firmware from wlc, it will be OK.
thanks for help for now.

Converting back AP 2600 from Autonomous to LWAPP

Hello,
I have Cisco AP 2600, Previously i had converted it from LWAPP mode into Autonomous-Mode. But now I need to revert it back to LWAPP mode.
Can anyone send me the link on how to do it ?

HI Imran,
Yes you can convert it to lightweight. Just need the lightweight recovery image.
http://www.cisco.com/en/US/docs/wireless/access_point/conversion/lwapp/upgrade/guide/lwapnote.html
For the LWAP conversion, use the recovery image (example: c1140-rcvk9w8-tar.124-25d.JAL.tar). after thatuse the command on the autonomous AP priviledge mode.
AP#archive download-sw /force-reload /overwrite tftp://10.10.10.1/c1140-rcvk9w8-tar.124-25d.JA.tar

How can I verify CAPWAP/LWAPP access point?

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..

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.

I would like to confirm if it is possible to downgrade AP 1042 from CAPWAP to autonomous?
I want to buy the AP model AIR-LAP1042N-A-K9. But i don't sure if in the future it could support this feature.
Thanks in advance.

JOSE LUIS

Hi Jose,
here is the step by step procedure to convert CAPWAP to IOS
>> I request you to follow the below steb by step procedure to resolve the issue that we are facing..
-    Initially console in to the LAP using the console cable and issue the Command ' debug lwap console cli' from the AP# prompt . (This give us capability enter the config mode of AP and use it like Autonomous )
Ap>en
Ap#debug lwapp console cli OR Ap#debug capwap console cli
-     Now assign an IP address to Fast Ethernet interface of the AP which can be reach from the LAPTOP/DESKTOP . (Basically in the same range or able to ping and telnet)
AP#config t
Ap(config)#int fa 0
Ap(config-if)ip address
Ap(config-if)#no shut
Ap(config-if)#end
-    Download the IOS image: www.cisco.com downloads for 1042 AP series.
Cisco.com --- Click on the Support tab in top--- Then click Download software------ Choose Wireless --- Then select AP from product list-Then choose the AP model - choose IOS image..
http://www.cisco.com/cisco/software/release.html?mdfid=283445229&flowid=17961&softwareid=280805680&release=12.4.25d-JA&rellifecycle=ED&relind=AVAILABLE&reltype=latest
-    Open the TFTP server (We used TFTP D32 ) (make sure that the TAR file's name is shown as in the web site, because sometimes it gets renamed to "Download .tar" and if that happens you need to rename). Browse the TAR file and select it and click ok.
-     Go to enable mode of AP and enter the command:
-    archive download-sw /overwrite /force-reload tftp:///
That is..
If the laptop Ehternet interface is assigned the ip addess 10.0.0.4 with the mask of 255.255.255.0 and the AP fa interface is assigned the ip address 10.0.0.1 255.255.255.0 and if we are running TFTPd32 on the local laptop.. the nthe server ip address will be 10.0.0.4.. finally the command will be..
AP# archive download-sw /overwrite /force-reload tftp://10.0.0.4/ 1140-k9w7-tar.124-25d.JA.tar
lemme know if this answered your question..

CAPWAP Primary/Secondary/Tertiary Question

After going to the High Availability Tab in the WLC GUI and setting the primary, secondary, and tertiary, how do you see that in the CLI in the AP?
I tried using show capwap ip config, it doesn't show any entries at all?
And also, is there a command to do that in the CLI in the AP? to set the primary, secondary, and tertiary?
Thank you.

"ou need to run th config ap... from a WLC. You have autonomous AP's so you need to convert them to LWAPP and you also need a WLC to do this."
It's been converted to LWAPP, but haven't joined a WLC yet.
What I wanted to do was configure a primary, secondary before joining it to a WLC.
Because what I would of done is first have it join a controller, then go into the GUI and change the HA (High Availablilty) and add the primary/secondary controllers.
Thought if I could skip the first step and try to configure it from the AP.

Autonomous to LWAPP with Cisco Prime 2.2

Hello, I need to know if exist any procedure to convert Autonomous to LWAPP access point with Cisco Prime 2.2.

Here are the Steps Cristian.
To create an autonomous AP migration template, follow these steps:
Step 1 Choose Design > Configuration > Wireless Configuration > Autonomous AP Migration Templates .
Step 2 From the Select a command drop-down list, choose Add Template, then click Go . If you are updating an already existing template, click the applicable template in the Template Name column.
Step 3 Complete the required fields. For information about the field descriptions, see: http://www.cisco.com/c/en/us/td/docs/net_mgmt/prime/infrastructure/2-0/reference/guide/prime_infr_ref.html
Step 4 To view the migration analysis summary, choose Operate > Wireless > Migration Analysis .
Note: After an access point has been converted to lightweight, the previous status or configuration of the access point is not retained.
Hope this will resolve your issue ;)

If I purchase a LWAPP AP can I migrate it to non LWAPP

If I purchase a LWAPP AP can I migrate it to non LWAPP. If I purchase a non LWAPP AP can I migrate it to LWAPP, and then back to non LWAPP. Are there any advantages to buying a native LWAPP AP

Hi Friend,
Yes it is possible to convert LWAPP to IOS AP and also from IOS to LWAPP APs.
Even if you buy non lwapp ap you can convert it to LWAPP and again back to non LWAPP.
From NON LWAPP to LWAPP
http://www.cisco.com/en/US/docs/wireless/access_point/conversion/lwapp/upgrade/guide/lwapnote.html
From LWAPP to NON LWAPP
http://www.cisco.com/en/US/docs/wireless/access_point/conversion/lwapp/upgrade/guide/lwapnote.html#wp161272
Also the only advantage of buying a native lwapp ap is if your wireless network is only controller based then you do not need to go through all procedure of converting your APs from NON LWAPP to LWAPP and you can start using it directly.
