Auto speed negotiation for 10G Base-T on FortiGate 100xF devices

Auto speed negotiation on the 10G Base-T interface allows the 1G/10G copper ports on the FortiGate 100xF devices to automatically handle both 1G and 10G speeds and duplex settings, eliminating the need for manual adjustments.

config system interface
    edit "port1"
        set speed auto
    next
end

Example

• When the peer uses 1G and the speed is the default value:

  config system interface
      edit "port1"
          set vdom "root"
          set type physical
          set speed 10000auto
      next
  end

  The port is down because of the different speeds:

  # get sys int physical port1
  == [onboard]
          ==[port1]
                  mode: static
                  ip: 0.0.0.0 0.0.0.0
                  ipv6: ::/0
                  status: down
                  speed: n/a
                  FEC: none
                  FEC_cap: {none}

• After the speed is set to auto:

  config system interface
      edit "port1"
          set speed auto
      next
  end

  The port is up and auto negotiates to the correct speed and duplex setting:

  # get sys int physical port1
  == [onboard]
          ==[port1]
                  mode: static
                  ip: 0.0.0.0 0.0.0.0
                  ipv6: ::/0
                  status: up
                  speed: 1000Mbps (Duplex: full)
                  FEC: none
                  FEC_cap: {none}
