FortiGate Firmware | Using the CLI |
5Enter the following command to copy the firmware image from the TFTP server to the FortiGate unit:
execute restore image <name_str> <tftp_ip4>
Where <name_str> is the name of the firmware image file and <tftp_ip4> is the IP address of the TFTP server. For example, if the firmware image file name is image.out and the IP address of the TFTP server is 192.168.1.168, enter:
execute restore image image.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, upgrades to the new firmware version, and restarts. This process takes a few minutes.
7Reconnect to the CLI.
8Update antivirus and attack definitions, by entering:
execute
Reverting to a previous version
This procedure reverts the FortiGate unit to its factory default configuration and deletes IPS custom signatures, web content lists, email filtering lists, and changes to replacement messages.
Before beginning this procedure, it is recommended that you:
•back up the FortiGate unit system configuration using the command execute backup config
•back up the IPS custom signatures using the command execute backup ipsuserdefsig
•back up web content and email filtering lists
If you are reverting to a previous FortiOS version (for example, reverting from FortiOS v3.0 to FortiOS v2.80), you might not be able to restore the previous configuration from the backup configuration file.
Note: Installing firmware replaces your current antivirus and attack definitions, along with the definitions included with the firmware release you are installing. After you install new firmware, make sure that antivirus and attack definitions are up to date. You can also use the CLI command execute
Note: To use this procedure, you must log in using the admin administrator account, or an administrator account that has system configuration read and write privileges.
To use the following procedure, you must have a TFTP server the FortiGate unit can connect to.
