Hi, 

 

I am deploying 2 FortiSwitch 3032E as core/Tier1 and Multiple FortiSwitch 2048F as distribution/Tier2. 3032E are now manage by FortiGate 3701F, when I am adding the 2048F I connect the port using 100G transceiver to 3032E. There was no LED light indicating that is not physically connected correct? And on the FortiGate side, I cannot see the serial of the FortiSwitch. What do I need to do next.

 

thanks.

Hi @AEK,

 

Update on my issue, seems the problem is related to firmware version compatibility. After upgrading the FGT and FSW to recommended version, FSW slowly showing and been populated to FGT automatically.

Do you mean the connection between FSW & FGT is not working or between FSW & FSW?

FSW to FSW physical connection is not working, and I cannot see the FSW to FGT automatically. Which I think I need to enable the auto-discovery-fortilink enable to the port.

Did you connect to a 100Gb port on 2048F side as well?

And which cable type are you using?
