(WLC1) > transfer upload filename wlc-backup. Follow the below screenshot & you can see the CLI commands required.

Now you are ready to upload WLC config on to your TFTP server from WLC CLI console. I have used TFTP method in this example as show in the below screenshot. Then open up your TFTP or FTP application on your PC. You can do this with following CLI command assuming your PC is having 192.168.1.x/24 address. 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). Below shows the 5508 controller ports & number 2 is the service port where you need to connect your PC. 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. First you need to upload the existing WLC configuration on to a TFTP/FTP running on your laptop. Let’s say you have to replace your WLC with a new one (same hardware model) due to some issue. But you have to practice it multiple times to remember the CLI commands involved.(you can do this via WLC GUI as well) Even though it is not that simple as in IOS devices, process is not that complex as well. In WLC you have to use TFTP or FTP method to upload or download configuration file “From” or “To” WLC. Once it boots up with zero config you can simply upload the backup config by “ copy flash:backup- running-config” & then save the config.įor my CCIEW lab studies I have to load initial configuration into WLC very frequently. Once you console into the device you can erase start-up config by “ erase startup-config” CLI command & then reload the device.

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. Below shows CLI command to backup a device config to a file named as “backup-” & store it in flash disk. you can simply backup your router/switch configuration in to flash disk by “copy run flash” CLI command. In a Cisco switch or Router (running on IOS) taking a configuration backup & restore is very easy task.
