In a Cisco switch or Router (running on IOS) taking a configuration backup & restore is very easy task. you can simply backup your router/switch configuration in to flash disk by “copy run flash” CLI command. Below shows CLI command to backup a device config to a file named as “backup-2013-01-25” & store it in flash disk.
#copy running-config flash:backup-2013-01-25
In a situation where you have corrupted configs or due to any other reason if you want to restore a backup config you can do it very easily. Once you console into the device you can erase start-up config by “erase startup-config” CLI command & then reload the device. Once it boots up with zero config you can simply upload the backup config by “copy flash:backup-2013-01-25 running-config” & then save the config.
For my CCIEW lab studies I have to load initial configuration into WLC very frequently. In WLC you have to use TFTP or FTP method to upload or download configuration file “From” or “To” WLC. Even though it is not that simple as in IOS devices, process is not that complex as well. But you have to practice it multiple times to remember the CLI commands involved.(you can do this via WLC GUI as well)
Let’s say you have to replace your WLC with a new one (same hardware model) due to some issue. First you need to upload the existing WLC configuration on to a TFTP/FTP running on your laptop. To do this you can simply connect your PC into WLC’s service port & assign a IP to your PC in the same subnet of the WLC’s service port. Below shows the 5508 controller ports & number 2 is the service port where you need to connect your PC.
If WLC’s service port is not configured then you can simply assign a IP to that port via console CLI.(I preferred CLI method as it is much faster than loading GUI for me). You can do this with following CLI command assuming your PC is having 192.168.1.x/24 address.
<WLC> config interface address service-port 192.168.1.200 255.255.255.0
Then open up your TFTP or FTP application on your PC. I have used TFTP method in this example as show in the below screenshot.
Now you are ready to upload WLC config on to your TFTP server from WLC CLI console. Follow the below screenshot & you can see the CLI commands required.
(WLC1) >transfer upload mode tftp (WLC1) >transfer upload datatype config (WLC1) >transfer upload filename wlc-backup-2013-01-25 (WLC1) >transfer upload path .

Transfer upload datatype can be any of the following, but of the configuration backup you need to select “config” option. transfer upload path given as “.” implies path location is root folder where you select on your TFTP server application.
(WLC1) >transfer upload datatype ? ap-crash-data Upload the ap-crash files. config Upload the system's configuration file. crashfile Upload the system's crash file. debug-file Upload the system's debug log file. errorlog Upload the system's error log. invalid-config Upload the system's invalid-config file. pac Upload a PAC (Protected Access Credential). panic-crash-file Upload the Kernel Panic Information file. radio-core-dump Upload the ap-radio core dump files. signature Upload the system's signature files. systemtrace Upload the system's trace file. traplog Upload the system's trap log. watchdog-crash-file Upload the Watchdog Information file.
Now you have to download this config on to your new controller which is having zero config. Through configuration wizard you can configure the initial parameters required. Remember to configure service port in the same subnet where your TFTP/FTP PC is in.

Update @4Dec 2013:
Chris: I am running v3.35 of Tftpd32 & please check your settings with below.
I found your post and it works great. People at TAC need to read your blog.
Thanks for the feedback & to know this is useful to you…
Found this post really clear and useful! Thanks man!
Thanks for the feedback
Great post. Found it very useful.
Thanks for the feedback…
Great tutorial. I have a question though. The upload is failing and Tftpd32’s Log viewer is showing me this error:
“error 123 in system call CreateFile The filename, directory name, or volume label syntax is incorrect”.
Any ideas on why this is?
This is to do with some of your setting of this app. Pls check your setting with mine (I have attached a snapshot at the end of the post. I am running v3.35 as well.
Works perfectly now! Thank you so much!
Great.. glad that worked for you….
Hey this is Great, I been to many thread until I fond this one. I didn’t pay attention on that /. (I’m not unix guy) I keep on entering target directory in WLC which was not necessarily . Thanks
Thanks for the feedback.
Yes “.” for the TFTP path should be sufficient as long as you put the image on TFTP root folder.
Hi, Great blog!
But Im wondering, how can i upgrade the backup image and leave the primary as it is. Or how can i copy the primary image to the backup image?
For an switch you usual copy the new firmware into the secondary (backup) image flash. And if you have an old firmware in the backup flash, how can i upgrade it?
I have to check this & get back to you… will update here once I get proper answer
I have now updated my three WLC HA+1 setup from 7.5 to 7.6. and found out how the primar vs backup image work.
The primary was 7.5 and it was active. And my backup was 7.3. Once you do the upgrading you will erase the image which is not active.
So the 7.3 was repalced with 7.5 and backup image became the active image. Primary became 7.6.
And once you reboot, the primary (if you choose that one) will be booted.
Thanks for the update & really appreciated.

Hi, can I use the configuration file from the 4400 to a 5500? or should I just configure manually?
You can, but you need to understand certain differences. For example in 5508, we are not configuring seperate AP Manager interfaces. So you need to slightly modify the existing 4400 configuration & then you can restore to a 5508.
The blog you’ve written is great. Straight forward and works well. Thank you!
Thanks & very nice to see it helps you.

Hi Nayarasi, excellent information in your blog!!!
I have a issue with my Cisco 4400 series WLC, I need upgrade the software because I have the version 18.104.22.168 and I need the version AIR-WLC4400-K9-4-0-219-0.aes (29 MB long), I known that this version can be downloaded from Cisco.com, but I don’t have a contract service with Cisco and for me is difficult to get one. I am preparing my certification in wireless.
What can I do? Do you know a public TFTP server or something where I can download it? Can you share that software image?
I am stuck with that issue, I really appreciate any help.
Thanks in advance.
I do not think this version(too old) even available in Cisco.com. I do not have it eitehr
I have 58 WLCs to manage and it is quite troublesome for me to take config backup one by one through TFTP. All the WLCs are added in Cisco WCS,
Is it possible to have a scheduled WLC configuration backup through Cisco WCS?
Yes Isuru, WCS can do regular backup of your WLC.
Refer this section of WCS
Thank you very much. I couldn’t find it before. Very useful.
Is it possible to upload existing web auth bundle from WLC?
My other question is how can I view WLC file system? I don’t know what is the name of the web auth bundle, which was originally downloaded to WLC by a pereson who origianlly configure WLC.
First of all, thanks for your posts. I find your blog quite helpful.
I am quite new to the WLC and was wondering if backing up your config this way would be the same as the Upload File from controller in the commands tab of the GUI screen.
Is there any benefit on doing this from the service port like you are doing?
Yes, you can take the backup via GUI & it would be the same result.
There is no extra benefit by doing it via Service port.

Mohammad Hassan said:
I am very thankful for this document. very very useful. You save my day…..
Thanks Hassan for feedback. Good to see this post helps many others
I have 5 identical kits that travel to events. I pulled a backup of each WLC with instructions to restore the config after major changes were made and the event was done. I started running into some problems with some devices on the network after doing this. After doing some investigation between the 5 WLCs and the various backup files, I determined that not all of the configuration is backed up.
Controller > General > AP Multicast mode and address are missing
Controller > Multicast > All of the snooping and global multicast modes are missing
I am currently running 22.214.171.124 and have seen this problem going back before 7.x
I am now looking for the commands so that I can insert them into the backup file manually to see if that fixes things.
Thanks for your information.
Useful to others..
I just backed up a 126.96.36.199 WLC, and verified the the two missing items mentioned by the OP are in fact in my config file. There are in the section of commands that start wtih: Config network multicast
Stephen Bygrave said:
Hi, is it possible to combine these commands into a single command?
I do not thinks so. Simply I will put these into notepad & paste them in one go.

i have two Cisco WLC-2504. what i want to do is to configure HA (High availability ) between the WLCs such as the configuration of Primary WLC is automatically sync with the Secondary WLC. is it possible to make sync up between this two WLC?
Refer this doc & see how to configure N+1 HA configuration on WLCs.
Since I recently went through this, the short answer is that you cannot do what you are asking with the 2504’s. You can use them with the HA-SKU, but the configurations are not synced. I like to call this poor man’s HA, but it’s better than nothing. You have to manually keep the configurations in sync, or use Cisco Prime which may not be worth it if you only have a few controllers to manage. I honestly wish they had an easier way to sync the configs, but they don’t.
On the other hand, the 5508’s support true statefull HA, where not only are the configurations synched, but so are the active client and AP sessions. I believe that Cisco calls this mode AP-SSO. We have at our headquarters office and it works really well. All remote offices have a pair of 2504’s, and luckily we don’t make a lot of changes.
Thanks for sharing ur experience with this.
Is it possible to restore my WLC with ver 7.0 backup configs into a new WLC with ver 8.0? will there be any conflict or data loss?
Yes, it should work. Since 7.x to 8.x upgrade is direct configuration should be compatible.
Here is the link to the release notes
when try to put backup on new wlc, show me this error
¡Advertencia! No AP se van a plantear a menos que se establezca la hora.

Sorry, did not understand language of the command output. but I suspect your backup config taken in different to the AireOS version of the new controller, you are trying to restore.
If possible downgrade new controller to the same version of your config backup
Let me know the two versions to see the compatibility
Love your blog, extremely useful!!!
Question, I am running a 5508 and recently purchased an 8510. They are both running 8.0, I performed a backup of the 5508 config and uploaded it to the 8510, however, now I am not able to login to the 8510.
Is this because of the crypto? I don’t see an option to export & import the keys.
I assume if I restored the config to a new 5508 this would also happen. Any idea how I could get around this? Factory reset and then re-import config but omit username and passwords?
Or do you know how I can migrate from a 5508 to an 8510 without having to configure everything manually.
I haven’t done this.
I would try factory reset and re-import config without login related config lines. Then manually configure those login information.
Manuelito Caoile said:
How do you omit the login information? I am about to replace a 5508 with 8510.
Haven’t done this by myself.
usually “config mgmtuser x” commands are related to local management user of a WLC
Hi, I uploaded config file from vWLC and downloaded to 2504 WLC. It is showing update process successful and reboots. But, its overwrites the username and password I have put when I initially config 2504. I thought it overwrites with vWLC username/password but it’s not working either. I tried so many times but, its overwrites password for something I can not think of.
Thank you for your post. I want to take a backup from 2506WLC controller and it said “% Error: Config file transfer failed – No reply from the TFTP server”. I can ping my server. I can also take a backup from switches and routers on the same Lan. I am using TFTP64. The setting of the tftp also resembles. Could you please help me?
Problem solved!!!! I was connected using wireless. I needed to be on the wired medium or an AP thats not on WLC.
Good to see you got it yourself.
I manage two 5508 WLCs in France DC and I need to take a configuration backup. But the backup procedure via GUI COMMANDs-> Upload file is not working for these two WLCs and I guess there might be a firewall in between which is blocking TFTP / SFTP / FTP, etc. (These two WLCs are not attached to Prime / WCS, ). But I have SSH access to those WLCs.
I wonder why the config backup via GUI (.cfg file) and “show running-config” in the CLI is different. I want to clarify below points.
1. Lets say I have taken a “show running-config” via CLI and save it as a .cfg file. So in any case of this WLC failure, can I use this file to upload to a new same model WLC via GUI – COMMANDS->download file option? And WLC will have exactly same config?
2. If not, is there any way that I can get configuration backup of these two WLCs under the current situation?
Thank you very much in advance.

If you talk about AireOS WLCs, then I do not think so (known public)
Bill D. said:
Great post! Is there a reason you would use the service port and not the ethernet management interface (4404 w/ 1 SFP)? Thank you!
You can use in-band management as well. To do that you have to setup trunking properly.
Setting up out of band management via service port is an easy option, hence used that. So when you upload new configuration, there won’t be any distruption even management port configuration alter during the process.
Bill D. said:
Can we use the management interface (Copper SFP) in the same manner as the Service Port?
Bill D. said:
I found I could use the same commands from the CLI, but with the controller management interface instead. Is there a way to get to a command prompt, after a factory reset, without running through the configuration dialogue? Since I was forced to configure the WLC, I was able to config both the service port and management interface, then run your commands from the CLI.
I also found you cannot use a “Show Running-Config” file in place of a file you’d get when uploading a backup from the controller. The difference between the two is obvious when you open them. The show runn is like you’d expect to see, but the backup file has all information run together line after line, and in a different order than the output from the show runn.
FYI Isuru 🙂
What about the Web Auth (captive portal) information including the archive bundle and the certificate? I don’t see that this information is contained within the config backup. I suspect that the config must be restored, then the certificate and web bundle re-downloaded to the controller?
Rob Frank said:
Downloading raw and processed running config from Prime. When I download either to the 2504 I get the messages below. I see these configured when viewed in a note viewer. Why is this happening?
My intent is to configure a newly replaced WLC with its archived file after I minimaly configred the WLC.
Replaced 2504 and Prime backup copy are V8.0.121
Mandatory CLI config interface address management is missing in the downloaded config
Mandatory CLI config interface address virtual is missing in the downloaded config
Mandatory CLI config interface port management is missing in the downloaded config
I haven’t use prime for this purpose. It would be faster if you could check with TAC (as long as you got that support)

Great post, but I have a question. What if you need to replace a failed Secondary unit? What information needs changing from the Primary backup configuration to enable it to work on the Secondary, is it just the Management Interface IP address and Redundancy-management interface IP, and Unit mode to Secondary?
If secondary unit in HA pair fails though, and you upload the Primary backup configuration, what parameters do you need to change to re-enable the HA between Primary and Secondary units? Is it just redundancy management and management IP addresses and Unit from Primary to Secondary?
Rob Frank said:
Thanks for your reply. Here is the problem. I have hundreds 2504 WLCs and at times a few will go down and need to be replaced. My field techs go to the site with a new 2504 that is minimally configured to get it up on the network.
I want to take the backedup configuration(raw) from prime and down load it to the newly replaced WLC. However i am getting errors stating that the mgt , virtual, and mgt port are missing. I can see these configs in the backedup raw config and also see this configured in the minimally configured WLC that is now installed.
Why am I seeing messages that the three configs are missing?
After uploaded firmware to the WLC. SYS-blinking amber & ALM-blinking amber.Console output disapper ?
console output should not disapear, closely look at what messages it gave, prior to this. I will give some clue

Waiting for you reply
You can’t do this.
You have to get WLC OS from cisco.com download page
I tried to upload config file directly from controllers to FTP server (Filezilla in my case) and all went good except one controller where i got below error:

If i try backing up config from controllers via Prime to FTP server (Filezilla), the same controller have issues backing up config to FTP server.
Any idea, what could be an issue what that controller or something ?

Hi Nayarasi,how are you doing?
I need migrate one WLC 2504 to Virtual WLC, can I do a backup from 2504 and a restore on Virtual?
After this I will do a upgrade to the last version Available from Cisco.
I saw your post on CSC & responded. Hope that is fine with you.
Chris S. said:
Hey great article! Love your blog!
Just to be sure:
When I download a config file of a WLC, does it really include EVERYTHING of this controller. So when I push it to another one (like vWLC to vWLC or 2504 to 2504), there is literally no difference between them?
Yes, as long as both in same AireOS version it should work like that.
With code mismatch, you can face some command syntax differences
Not 100%. It will not include SSL certificates you’ve uploaded such as for the captive portal, and it will not include your custom webpage archive for the captive portal (if you uploaded one). Both of those have to be uploaded to the new controller.
Thanks for correcting me on this Jeff, appreciate it
great post, very handy for a not really known into WLC cisco guy 🙂

Did you ever get this resolved? I have a 5508 and new environment needs a quieter device so I’m going to use a 2504. I’d like to avoid the rekeying of the setup manually. Were you able to get your config to move correctly between different controllers?

Yes, if you go to “COMMANDS” tab, you will see UPLOAD files option. You can specify “configuration” file type & use your TFTP server details to get a back up of your configuration.

Thank you for sharing your knowledge that help me to restore my WLC, now we have second WLC as standby with HA, and the commands to get backup config its not available on the standby one, do we need to get backup from this device ? if yes how ? because there is some different config on the standby one for example the interfaces config.
Thanks for your feedback
In a HA setup, the typically active unit configuration will be sync with standby. I do not think you need to get back up from two of them independantly
Would you be able to provide a backup/template of a generally well optimised wlc config, so I can simply adjust WLAN name/pass and have the system basically ready for use?
I know that systems should be designed on a per deployment basis but I’m just stepping foot in the cisco world and wanted to see what an ‘ideal’ or ‘close to ideal’ config looks like… I currently run a 5508 with 3802i AP’s in my office and would love to just be able to load a config on and just adjust WLAN settings without having to worry about whether there are other settings that I have left unoptimised whilst I can also look through the settings and learn what should be tweaked and where.
Thanks in advance for any help in this matter
