Question

I Cannot estabilsh the connection between FortiGate 1000D And FortiGate 3700D

Greetings All, 

 

we are trying to establish the connection between FrtiGate1000D and FortiGate 3700D through the Fiber Optic.

and we have checked the connectivity plus the SFP but still, the connection not working between them

 

the SFP in both sides is 1G and the port has been enabled in both side as auto.

 

does the lack of license the reason of this issue for the connectivity between the FortiGate.

 

Please find the attached FYR.

    Very doubtful an expired licensing would affected physical connections unless you have firewall policies on the ports with expired UTM policies applied to them.

     

    Are you trying to connect both fgts through a fiber switch or direct-to-direct ports on each fgt?  Have you performed diag hardware device info <nic name> on the CLI to see if there is a duplex/speed or any rx/tx errors (do these error counters grow?)

    Do you get link lights? Perhaps the fiber needs flipping. (send-send and receive-receive won't work)
