10GB SFP+ recognized as 1GB - Question

Hi,

I do have a RB3011UiAS and a CRS326-24G-2S+ connected via a 10GB SFP+ DAC. Even though both ends are forced to 10GB full duplex they are only shown as 1GB connection within Winbox. The CLI though shows “speed=10Gbps”.

Anybody experienced that? What is the truth?

Regards,
Starbug

Hey, 3011 is only SFP capable: see https://i.mt.lv/cdn/rb_files/RB3011UiAS-160307123613.png

So max is 1gb

Thanks, actually I’m embarrassed since I had a look at the block diagram several times and thought even though the channel only provides only 1GB to the CPU it should have a 10GB connection. But I didn’t notice it’s an SFP only and not SFP+. Aarrrrg.

The 4011 has an SFP+ port. If you upgrade to that you should get the full rate.
