Technical Tip: How to upload FortiSwitch images to FortiGate for firmware staging

[laltuzar]

Description

This article describes the commands to upload FortiSwitch images to FortiGate for firmware staging. This step was omitted on Upgrading MCLAG peer group switches from FortiSwitchOS 7.4.2 and earlier to FortiSwitchOS 7.4.3 and ... and Upgrading MCLAG topologies, so it is a bit confusing on how to continue.

This article also describes the steps to stage an image directly on FortiSwitch.

Scope

FortiOS v7.0 and newer.

FortiSwitch OS v7.0 and newer.

Solution

To upload a firmware image to FortiGate using FTP or TFTP servers, execute the commands below:

• FTP server: 

FortiGate # execute switch-controller switch-software upload ftp <string> <ftp server>[:ftp port] <Enter>|<user>

• TFTP server:

FortiGate # execute switch-controller switch-software upload tftp <string> <tftp server>

Example:

FortiSwitch firmware image uploaded to FortiGate

After the image is successfully uploaded to FortiGate, the administrator can view it listed with the command below.

FortiGate # execute switch-controller switch-software list-available

Then, the administrator can continue staging the images.

It is possible to upload the image directly to FortiSwitch as well:

• FTP server:

FortiSwitch # execute stage image ftp <string> <ftp server>[:ftp port] [<FTP_user_name> <FTP password>

• SFTP server:

FortiSwitch # execute stage image sftp <string> <sftp server>[:sftp port] <SFTP_user_name> <SFTP password>

• TFTP server:

FortiSwitch # execute stage image tftp <string> <tftp server> [<source_IPv4_IPv6_address>]

Note: Uploading FortiSwitch images to FortiGate via SFTP is not supported.
