Interface arrow icon

[Elthon_Abreu]

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

[Jeff_FTNT]

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

[Elthon_Abreu]

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]

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.
