Does anyone know what this means arrow in the interface/port 2 (See figure attached)?

    Yes, I am sure.

     

    Please check your interface status on FGT like:

     

    #get hardware nic mgmt2 ..... Link                            up Speed                          100 Mbps Duplex                          half

    That mean "Half-duplex" for this port, thanks

    Jeff_FTNT,

     

    My settings on the FortiGate and Switch are set to "auto". Are you sure that the arrow means just that?

    I even opened a ticket (1307217), but the support did not know infomar me what it meant.

     

    Thanks

    Jeff_FTNT,

     

    I ran the command you said and really the interface was "half".

    ========== Link Status ========== Admin :up PHY Status :up PHY Speed :100 Duplex :Half link_status :1

    ============================

     

    The curious was that both doors were in auto mode (in the Switch and FortiGate). 

     

    Thanks,

    What kind of switch?  It look like  both switch and FGT are happy with half-duplex.Thanks.

    Jeff_FTNT,

     

    It's a CISCO Catalyst 2960. The Half mode causes problems in my network.

     

    Thanks

    FG-600C Wan2 port is 1000M port, may be have some inconsistency with 100M Switch.

    Try one 1000M port or force change Switch port setting. Thanks.

    I'd check the cable as well, and any connectors (panels) in between ports.

    Gentlemen,

     

    To knowledge from all, there is a bug with the Fortgiate 600C which causes problems in auto-negotiation of the interface speed.

     

    Thank you all for the answers.

    For what it's worth, our company manages some 60-80 remote sites in rural areas (mostly sat or terrestrial fiber connections) with about 40-50 fgt devices deployed in about half of those sites -- we found auto-negotiation doesn't works even 80% of the time with the sat/radio/switch (mostly 2960s) equipment we are connecting the fgts too.  The general rule of thumb we have been following is to ether force the duplex/speed on both sides of the WAN connection or just set one side to auto-negotiation and force the other side.
