Fortilink speed negotiation

[AliAbdulrazaq]

Hi,

I am having an issue between 248E switch and 124E, the fortilink speed downgraded to 100M instead of 1G, everything on the topology is 1G. I tried to set the speed on the ports to 1g but that brought the connection down so I had to set it back to auto. Thanks in advance

Thanks Everyone! It ended up a bad cable caused that slow negotiation, not easy to find but checking the cable from cli helped to pin point the issue. Thanks
