Upgrading OpenSSH on WLC.

Hi guys,
Do anyone here know how can I upgrade the OpenSSH on WLC to version 5.0 or later.
Please advice. Thanks.
Azmir

Your best bet is to open a TAC.
From my seat in the house, the only way to upgrade any software component on a WLC is to upgrade the entire WLC code.

How to upgrade OpenSSH without macport or homebrew

I would like to upgrade openssh/openssl to their latest releases via the terminal. All I can find is how to do it with macport or homebrew - I don't want to use these.

Thanks!

OS X isn't like Linux. If there is a security patch that needs to be installed, you don't have to do it yourself. Apple takes care of it for you. In this case, Apple had stopped using the affected library some time ago. So updating the library won't help you very much because very little native Mac software would even be that library.

Can we upgrade IOS in WLC 5508 through CISCO prime?

I have CISCO prime 2.0 and CISCO WLC 5508 HA SSO pair.
I would like to upgrade the software code for the WLC HA pair.
Can I do through the CISCO prime ......
As per the link :http://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/7-5/High_Availability_DG.html#pgfId-43571
1. After the WLCs are configured in the HA setup, the Standby WLC cannot be upgraded directly from the TFTP/FTP server.
Prime do the upgrade through FTP server , so will it be ok if we do the upgrade through it, for HA WLC.

Please check this link to upgrade wLC software in HA setup.
http://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/7-5/High_Availability_DG.html
Once the Primary WLC complete the upgrade , it will transfer the entire image to the Standby WLC via the Redundant Port.

Issues upgrading code on WLC

Hi all,
Im having issues uploading code on a WLC in a remote location. The WLC is running 4.0.217.0 and im trying to upgrade to 4.2.209.0. I have checked the upgrade path from current to new version and there is no issue upgrading directly from one to the other.
The issue occurs when I try and upload via TFTP, the Controller starts the code upload and only downloads a portion of the code, starts the extraction then fails with the following messages:
-Sanity check fails
-TFTP failure while storing in Flash
-Failure while storing in Flash.
I've done a debug from the controller and this is the output:
Wed Oct 13 01:56:22 2010: RESULT_STRING: TFTP Code transfer starting.

I've tried using a TFTP server (both 3Com and TFTPd) on a local server on site and its still fails. I've also tried using several servers
as the TFTP server and still no luck.
Does anyone have any idea why this is still failing? Could this possibly be a lack of space issue on the flash?
cheers
Rob

Hi,
"Sanity check failed on file. The file was not downloaded completely! " - This error log is seen only if upgrade path is not right or if TFTP server which you are using does not support transfer of mor ethan 32MB file.
I understand that you have already tried many tftp servers. If in case, you haven't tried tfttpd32 yet, please download it and give it a try as Cisco recommends to use tftpd32 server.

S/W upgrade on 4402 WLC

We have a 4402 with S/W 3.2.150.6 and want to upgrade to 4.0.217.0 to match other controllers. We use APs which were converted to LWAP. My concern is, will the WLC 'forget' the self signed certificates it got when the APs were converted?

Certificates, self-signed or otherwise, should not be a problem for your upgrade. You can always create new self-signed certs on the controller and the AP's after the upgrade.
Be sure and read the release notes and ensure that your APs are supported in the newer release, and that the Open Caveats will not cause problems for you.

Access point are not coming up after upgrade image of WLC

Hi,
I have AIR-WLC4402-50-K9 WLC i that current IOS is 7.0.98.218 and i upgraded with 7.0.116.0 IOS but after upgrading and reboot the WLC from 15 access point 3 access point are not coming up and 12 are coing up and working fine (4 1142 and 11 1131 series access point) 3 which are not coimg is 1131 series access point. when i login with console to 3 access point its rebooting 2 times and coming on ap: prompt.
In between that i reloaded the WLC one more time because from 15 acess point only 4 aceess point are came up and i also cleck the show boot on wlc its output is
7.0.116.0 (default)
7.0.98.218 (active)
so i reload the wlc and checked out of 15 acess point now 12 acess point are up and still 3 are not. And i also checked the output of show boot command its
7.0.116.0 (default)(active)
7.0.98.218
So i things its because of when 2nd time i reload the wlc the remaining 3 access point are getting image from wlc but because of reload its connection should be loss and error loading flash error are coming on acess point.
After that i recover the IOS for access point and convert into autonomus and from autonomus convert into Leightweight Access point. I also attached the procedure for recover the ios of access poing
But my question is why this 3 access point are not coming up is this happen's after upgrading wlc can any one please send me Step by Step WLC S/W Upgrade' process and if this this happens some time please send me any doccument related to this.

Sunil,
When you rebooted the controller did you do it from the Web GUI, the CLI, or did you physically reboot the controller? I believe and maybe incorrect but if your getting the ap: < prompt > that means that there is no firmware on the unit. If you have restored these to functioning autonomous unit and then re-converted them to Lightweight and it's still happening then we need to look at a debug output of what is happening when those AP's attempt to join the controller.
The capture you attached shows that it appears to join the controller and get a config, but are you saying that when it reboots again it stops working?? the other thing I would reccomend is clear out the flash memory since your capture shows the possibility that there are several copies stored there.
Hope this helps.

Upgrade problem with WLC 3750

Hello
I've upgrade the controller 3750 from the version 4.1.171.0 to the version 4.1.181. After this upgrade few AP are not anymore associated to the controller and I receive the following message
Failed to authorize AP with Base Radio MAC 00:13:c3:4c:88:b7. Authorization entry does not exist in Controller's AP Authorization List.
The controller is in Master Controller Mode and I've all AP in the AP Policies
Thanks
Fabrice

When you upgrade Cisco Aironet APs from autonomous Cisco IOS Software to lightweight mode, the LWAPP Recovery Cisco IOS image is the software that is loaded. The LWAPP Recovery Cisco IOS image does not support OTAP. In order to support OTAP, Aironet LAPs must first join a WLC in order to download a full LWAPP Cisco IOS image.

Should I upgrade my 2125 WLCs?

I have 2, 2125 WLCs in my production network with the system software, 7.0.98.0. I know this is pretty old but it's working for me. I need to purchase 1262 LAPs and although I read that software version 7 and higher should support them I'm concerned about the software being old. Does anyone know if theres a big benefit to upgrading my WLCs? I'm just afraid of my LAPs disassociating and not coming back. Thanks for any advice! -Mark

Yahya, I was wondering if you could confirm that my WLC's with the current software (7.0.98.0) could support AIR-CAP3502E-x-K9 APs? Do you know if these APs are going to be discontinued any time soon? Also, I see that single band and dual band are available. Does single band mean there would only be 3 connections for external antennas or are there 2 radios that support 6 antennas all on the 2.4Ghz band but on different channels?
Thanks for the help!
Cisco states that only the following APs are support on the 2125:
Q.
What access points are supported by the Cisco 2100 Series Wireless LAN Controller?
A. The Cisco 2100 Series Wireless LAN Controller supports Cisco Aironet access points running Lightweight Access Point Protocol (LWAPP) only. This includes any LWAPP-enabled Cisco Aironet 1130, 1230, 1240, 1250, and 1500 Series access points.

Upgrade Software Version WLC 5508

Dear,
i try to upgrade the software from 6.0.199.4 to 7.5.102
can we do it directly or we shoud upgrade gradually first from 6.0 to 7.0 then 7.5 ?
when we try from TFTP it give error [code file error disconnected- unknown error]
tru FTP error is [cont send replay disconnected]
Can you Help me Please

addition to Sandeep & Scotts feedback,
When you do the upgrade, make sure your 5508 FUS also get upgraded to latest version 1.9.0.0. Here is the release notes for that
https://www.cisco.com/en/US/docs/wireless/controller/release/notes/fus_rn_OL-31390-01.pdf
This process will take 30-40min & do this within a sufficient outage/maintenance window.
Here is the release notes for 7.4.121.0(7.4MR2) the one I would recommend
http://www.cisco.com/en/US/docs/wireless/controller/release/notes/crn74mr02.html
Also refer the compatibillity matrix to see which product it will support depending on the products that are available at your environment

WLC 5508 upgrade

Hi All,
We currently have 4 x WLC 5500 (AIR-CT5508-K9) V01 and V02
So two in one datacenter and the other two in another datacenter. They are connected via Mobility group to and BOYD open wifi with an Anchor WLC the other 1.
All four of them are 7.4.110.0 and the APs we use are AIR-LAP1142N-E-K9 and AIR-CAP2602I-E-K9.
We are looking to get 2700 or 3700 AP so we can use 802.11ac, but we need to upgrade all WLC to 7.6.130.0.
1. is it a direct upgrade from 7.4.110.0 to 7.6.130.0?
2. If I upgrade one datacenter one weekend and the other next weekend, during that week two WLC would be 7.4 and other two 7.6 would it break or cause issue with Mobility group to and BOYD open wifi with an Anchor WLC?
3. Can any please provide step to step guide for the upgrade from 7.4 to 7.6?
Many Thanks
appreciate it :)

Hi Rasika,
Many Thanks for your reply and help!
1. In regards to Upgrade the FUS, is it required to be upgraded once the WLC are upgraded to 7.6 or is just good practice?
2. Or I can I upgrade the FUS another time?

Upgrading from Prime 1.2 to 1.3 - What about WLC version?

If I upgrade to prime v1.3, from v1.2, am I required to upgrade my WLC controllers to v7.4, or will my current version (v7.2) work fine?
Thanks.

No upgrade to your WLCs is required. Any v7.0 or later should be fine. See the Release Notes here for details.

Wlc 2504 7.4.100 to 7.4.110 upgrade fails

Hello,
I've got a strange behaviour while upgrading my 2504 wlc from 7.4.100 to 7.4.110. I used the gui procedure to transfer the updated aes file to the wlc. The procedure started fine, finished downloading, and then the wlc got completely stuck on "Writing New RTOS to flash" message, all ap loosed connection all clients down, claimings, etc... Then after more than 10 minutes watching my laptop screen I decided to hard reboot the wlc.
Initially I saw the new image booting but, at the end, I finally figured out that the backup image instead booted and the show boot from the controller shows the following:
(Cisco Controller) >show boot
Primary Boot Image............................... 7.4.110.0 (default)
Backup Boot Image................................ 7.4.100.0 (active)
The controller now is working fine with the old image, but I need the upgrade.
What do I have to do now ? I didn't understand what happened.
Thank you for your help
bye

Upgrading to Controller Software Release 7.4.100.60
Guidelines and Limitations
• When H-REAP access points that are associated with a controller that has all the 7.0.x software releases that are prior to 7.0.240.0 upgrade to the 7.4.100.60 release, the access points lose their VLAN support configuration if it was enabled. The VLAN mappings revert to the default values of the VLAN of the associated interface. This issue does not occur if you upgrade from 7.0.240.0 or later 7.0.x release to the 7.4.100.60 release.
• While a client sends an HTTP request, the Controller intercepts it for redirection to login page. If the HTTP request intercepted by Controller is fragmented, the Controller drops the packet as the HTTP request does not contain enough information required for redirection.
• We recommend that you install Wireless LAN Controller Field Upgrade Software for Release 1.7.0.0-FUS, which is a special AES package that contains several system-related component upgrades. These include the bootloader, field recovery image, and FPGA/MCU firmware. Installing the FUS image requires special attention because it installs some critical firmware. The FUS image is independent of the runtime image. For more information, see http://www.cisco.com/en/US/docs/wireless/controller/release/notes/fus_rn_1_7_0_0.html.
• If you are using a Cisco 2500 Series controller and you intend to use the Application Visibility and Control (AVC) and NetFlow protocol features, you must install Wireless LAN Controller Field Upgrade Software for Release 1.8.0.0-FUS. This is not required if you are using other controller hardware models. For more information, see http://www.cisco.com/en/US/docs/wireless/controller/release/notes/fus_1_8_0_0.html.
• After you upgrade to the 7.4 release, networks that were not affected by the existing preauthentication ACLs might not work because the rules are now enforced. That is, networks with clients configured with static DNS servers might not work unless the static server is defined in the preauthentication ACL.
• On 7500 controllers if FIPS is enabled, the reduced boot options are displayed only after a bootloader upgrade.
Note Bootloader upgrade is not required if FIPS is disabled.
• If you require a downgrade from one release to another, you might lose the configuration from your current release. The workaround is to reload the previous controller configuration files saved on the backup server or to reconfigure the controller.
• It is not possible to directly upgrade to the 7.4.100.60 release from a release that is older than 7.0.98.0.
• You can upgrade or downgrade the controller software only between certain releases. In some instances, you must first install an intermediate release prior to upgrading to software release 7.4.100.60. Table 2 shows the upgrade path that you must follow before downloading software release 7.4.100.60.

Upgrade wlc to 7.4.100.60 AP3600 crash

Hi,
I have in a LAB and wlc 5508 with V7.4.100.0 working with 3 lap 1242 and tow 3602, I made the upgrade to the new version 7.4.100.60 the wlc is OK, but the 3600 neve came up, I consol them and was in a "ROMMON"
AP:
I had to upload the image because the ap send an error with the image. then I tried to join the 3600 again with the wlc and when the wlc downloads the new image to the access point, the AP crash again.
Do you know why is this ??
thanks

Hi,
I do not have the crash info, I download the firmware into the wlc again, I try to join the AP and works OK, I think the upgrade in the wlc was kind of corrupt.
Now it is working good.
thanks

WLC upgrade to 7.0.98.0, WCS & Location Appliance to upgrade - Building maps location

Hi,
We recently upgraded about 24 WLCs (4402s and 5508s) from 6.x to 7.0.98.0. In order to support these WLCs through WCS, we also need to upgrade the WCS to 7.0.164 which is currently running at 6.0.132.0 (Linux OS). Same is the case with Wireless Location Appliance 2700 to be upgraded as well. Wireless Management system has number of building maps with AP locations.
Prior to upgrade the WCS / Location appliance we need to take the backup of these building maps, already stored to export after the upgrade. Kindly let us know the directory where all these maps are being stored, as during upgrade we will loose all the stored data / maps.
Thanks for your kind assistance.
Regards.
Shuja

Hi Shuja:
Who says you're going to lose all your maps and stored data during a WCS upgrade? The installer for WCS 7.0.164.0 will see the 6.0.132.0 installation and upgrade it in place, modifying the existing data to work in the new 7.0 format. The installer for WCS 7.0.164.0 will even ask you if you want to make a backup of this data before the upgrade process even starts, although it would be a good idea to pull a backup of everything before you start. (One can never have too many backups, right?) The backup application in your existing install should be at /opt/WCS6.0.132.0/backup . Run that application and it will prompt you for a location to put the .nmsbackup file.
The .nmsbackup file that results from a WCS backup is what gives WCS its portability across platforms (physical/virtual) and operating systems (Windows/Linux). It's essentially the lifeboat of WCS, containing the database, the maps, the licenses and other supporting files.
