In a Cisco switch or Router (running on IOS) taking a configuration fill-in & restore is very easy task. yous tin simply fill-in your router/switch configuration in to flash deejay by "copy run flash" CLI control. Below shows CLI command to backup a device config to a file named as "backup-2013-01-25" & store it in flash disk.

#re-create running-config flash:fill-in-2013-01-25

In a situation where you accept corrupted configs or due to whatever other reason if yous desire to restore a fill-in config  yous can practise it very easily. Once you console into the device you tin can erase get-go-up config  by "erase startup-config" CLI command & then reload the device. In one case information technology boots up with zero config you can only upload the fill-in config past "copy flash:fill-in-2013-01-25 running-config" & then save the config.

For my CCIEW lab studies I have to load initial configuration into WLC very oftentimes. In WLC you accept to utilise TFTP or FTP method to upload or download configuration file "From" or "To" WLC. Even though information technology is not that simple as in IOS devices, procedure is not that circuitous likewise. Simply you have to practise it multiple times to recall the CLI commands involved.(yous tin do this via WLC GUI also)

Permit'due south say you have to supervene upon your WLC with a new ane (same hardware model) due to some result. First you need to upload the existing WLC configuration on to a TFTP/FTP running on your laptop. To do this yous tin 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 yous need to connect your PC.WLC-Backup1

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 lot tin can practice this with following CLI command assuming your PC is having 192.168.1.ten/24 address.

<WLC> config interface address service-port 192.168.1.200 255.255.255.0

Then open up upward your TFTP or FTP awarding on your PC. I accept used TFTP method in this example as show in the below screenshot.WLC-Backup2

At present y'all are gear up to upload WLC config on to your TFTP server from WLC CLI console. Follow the beneath screenshot & you can see the CLI commands required.

Transfer upload datatype can be whatsoever of the following, merely of the configuration backup you need to select "config" choice. transfer upload path given equally "." 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'south configuration file. crashfile      Upload the system's crash file. debug-file     Upload the organization's debug log file. errorlog       Upload the organization'due south fault log. invalid-config Upload the arrangement'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 cadre dump files. signature      Upload the system's signature files. systemtrace    Upload the arrangement's trace file. traplog        Upload the system's trap log. watchdog-crash-file Upload the Watchdog Information file.

Now you take to download this config on to your new controller which is having zero config. Through configuration wizard yous can configure the initial parameters required. Remember to configure service port in the aforementioned subnet where your TFTP/FTP PC is in.
