System status

Reverting to a previous firmware version

 

 

To use the following procedure you must have a TFTP server that the FortiGate unit can connect to.

To revert to a previous firmware version using the CLI

1Make sure that the TFTP server is running.

2Copy the firmware image file to the root directory of the TFTP server.

3Log into the FortiGate CLI.

Note: To use this procedure you must login using the admin administrator account, or an administrator account that has system configuration read and write privileges.

4Make sure the FortiGate unit can connect to the TFTP server.

You can use the following command to ping the computer running the TFTP server. For example, if the TFTP server's IP address is 192.168.1.168:

execute ping 192.168.1.168

5Enter the following command to copy the firmware image from the TFTP server to the FortiGate unit:

execute restore image <name_str> <tftp_ipv4>

Where <name_str> is the name of the firmware image file and <tftp_ip> is the IP address of the TFTP server. For example, if the firmware image file name is

FGT_300-v280-build158-FORTINET.outand the IP address of the TFTP server is 192.168.1.168, enter:

execute restore image FGT_300-v280-build158-FORTINET.out 192.168.1.168

The FortiGate unit responds with the message:

This operation will replace the current firmware version! Do you want to continue? (y/n)

6Type y.

The FortiGate unit uploads the firmware image file. After the file uploads, a message similar to the following is displayed:

Get image from tftp server OK. Check image OK.

This operation will downgrade the current firmware version! Do you want to continue? (y/n)

7Type y.

The FortiGate unit reverts to the old firmware version, resets the configuration to factory defaults, and restarts. This process takes a few minutes.

8Reconnect to the CLI.

9To confirm that the new firmware image has been loaded, enter: get system status

10To restore your previous configuration if needed, use the command: execute restore config <name_str> <tftp_ipv4>
