Is there a reason that 10G isn't a default option for link speed? Is there a way to force to 10G? I guess it only appears when it has a recognized, capable SFP/cable inserted? I have read in some places that auto-negotiate is not possible with 10G links.
I'm having some issues getting my CRS305-1G-4S+IN switches to recognize some DAC cables. I have 2 switches and seems like I have had to fuss with both sometimes to get cables to be recognized, and with a few different brands of cables.
The most problematic cables currently are Nebula L45593-C216-D10 -- I somehow got them to work ONE time but have not been able to get them working since. Other cables are coming up fine. They ran all day once I had them up but when I restarted the switch they were down and I have not been able to bring them back up since.
Any suggestions? The only things I have been able to do to try to get different cables to work is turn on and off auto-negotiation on the switch and peer, restarts, unplug and replug cables etc. It would be nice to force these to 10G only so I don't have to wonder if the auto-negotiation setting is the issue. But the only speeds that come up are 10M/100M/1G
