Question

FortiSwitch 148F-POE and BT ADVA (United Kingdom)

Hi guys,

 

A long shot here, do any of you have experience on connecting a FortiSwitch 148F-POE to a BT ADVA (Fibre Ethernet Virtual Connection).

 

It woks fine with an HPE switch but we can't get it to work with a FortiSwitch 148F-POE.

 

We have tried disabling Spanning Tree, setting the FortiSwitch 148F-POE SFP port to 1Gb.

Still we get a red light on the connection at the BT ADVA box.

 

John.

I don’t have experience with BT ADVA, but it might be worth checking the auto-negotiation settings.

Also, could you attach the CLI output of get system interface physical?
