Need to force speed/duplex on a physical interface.


There's no GUI option, you must command-line:

forti$ config system interface
forti(Interface)$ edit wan2
forti(wan2)$ set speed 100full
forti(wan2)$ end

Possible settings for speed:

  • 1000full (if applicable)
  • 100full
  • 100half
  • 10full
  • 10half
  • auto
By default they seem to all be set to auto.


If there's a Virtual (or Hardware) Switch Involved

You can mess with individual members of virtual swtiches if need be, but it's through a different interface.

Note that the Hardware Switch shows up in the list as a virtual switch.

config system virtual-switch
  edit vs1
    set physical-switch sw0
    config port
      edit 1
        set port port1
        set speed xx
        set duplex xx
        set status [up|down]
      edit 2
        set port port2
        set …
