Description
This article describes how to configure a FortiSwitch port to allow Jumbo Frames.
Scope
This configuration is useful for all the FortiSwitchs.
Solution
Into the CLI run the following commands:
# config switch physical-port
edit port1
set max-frame-size 9000 <--- This value could be set into the following range: 68 to 16360
end
Update to the existing article:
If there is entry-level FortiSwitch which does not allow setting MTU (max-frame-size) on a per port basis, it is possible tp do as follows:
# config switch global
set max-frame-size 1500
end
Note.
For smaller size models in E and F series, the max-frame-size command is under the config switch global command.
