GUI and CLI different link speeds

RouterOS General

I’m working with a CRS309-1G-8S that’s doing something super odd. When I do a /interface ethernet print detail it shows the link for my SFP+ port at 1Gbps, but when I look at the interface in Winbox I get 10Gbps. Not sure which one to trust.

The correct way to see the link-speed and duplex-state in CLI is the command

/interface ethernet monitor sfp-sfpplus2

. You only printed the interface settings in CLI while you are looking at the interface statistics in Winbox.

Ps.: Interface-setting “speed” is only used when auto-negotiation is turned to “off”, see this wiki article

Thanks for the correction.
