Controller Based WLANs

How do I back up the flash on the controller?

Product and Software: This article applies to all versions of AirOS running on MC800, MC800-E, MC804, MC6000, MC5000, MC2400, MC2400-E, MC3200, MC3600 and MC200. 

 

Flash backup of the controller is typically done to backup all information from the controller that is stored on the flash memory. It can also be considered as the "current" state of the switch provided a 'write memory' is done before performing the flash backup. It should contain the following.

 

  • Software licenses and license database
  • Configuration files
  • Local user database
  • Global AP database
  • WMS database
  • Custom upload certificates
  • Custom upload CP pages
  • Any other files uploaded to the controller

To back up the flash:

 

From CLI

SSH/Telnet to the switch from your management terminal.

 

Run the following command:

 

(Aruba) #backup flash 

 

This command creates a file called 'flashbackup.tar.gz' and copies it back onto the flash card of the controller.

 

Copy the flash backup from the controller to a TFTP server using the following command: 

(Aruba) #copy flash: flashbackup.tar.gz tftp: <tftp-server-ip-address> flashbackup.tar.gz

 

From the WebUI

 

To generate the flash backup:

Navigate to Maintenance > Backup Flash > Create Backup.

To copy the backup from the controller to the TFTP server:

 

Navigate to Maintenance > Copy Files > Source Selection > "Flash File System" ~ [Choose the file from the drop down] > Destination Selection > TFTP Server ~ [Give the TFTP server IP address and the filename as 'flashbackup.tar.gz' (without quotes).]

TAC recommends backing up the flash periodically on to a TFTP server, so that the flash files are available in case of a switch crash or when TAC needs to look back to older configurations/files. 


To restore a required 'flashbackup.tar.gz' file to the controller:

 

From CLI

SSH/Telnet to the switch from your management terminal. 

Copy the file 'flashbackup.tar.gz' to the flash on the controller using the following command: 

(Aruba) #copy tftp: <tftp-server-ip-address> flashbackup.tar.gz flash: flashbackup.tar.gz 

 

Run the following command: 

(Aruba) #restore flash 

 

Reload the switch for new files to take effect.

 

From WebUI To generate the flash backup:

Navigate to Maintenance > Backup Flash > Copy Backup.
