How can I upgrade the software version of the device? Is there any change in the upgrade mode?

The software version upgrade remains unchanged, using the USB flash drive or the TFTP. The upgrade commands have certain differences.

1)    Version upgrade using the USB flash drive

Copy the software version file to the USB flash drive. Insert the USB flash drive to the USB interface of the device management board.

Configure the following commands to upgrade the version:

Upgrade usb0:/xxxxx (file name of the line board)

Show upgrade status (view the software version upgrade status)

Upgrade usb0:/xxxxx (file name of the management board)

Show upgrade status

After the software version is successfully upgraded, save the configurations and restart the device.

1)    Version upgrade using the TFTP

Configure the IP address of the MGMT interface to access the network. Ensure that the TFTP Server and the MGMT interface can successfully interwork with each other.

Access the Shell mode of the system and the temporary directory.

N18K#run-system-shell

#cd /tmp/vsd/0*** (This directory corresponds to the tmp directory of the system, queried using the N18K#dir tmp command)

Tftp -g 200.1.1.1 -m -r lc.bin (the file name cannot include brackets)

Exit the Shell mode and run the following configuration commands:

Ruijie#upgrade flash:lc.bin force (upgrade the version of the line board)

Ruijie#upgrade flash:cm.bin force (upgrade the version of the management board)

After the software version is successfully upgraded, save the configurations and restart the device.

Remarks: The versions are saved on the device for archive after the upgrade.
