Interface arrow icon

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

Yes, I am sure.

 

Please check your interface status on FGT like:

 

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

 

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,

Jeff_FTNT,

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

Thanks

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

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.
