I’m having some issues with new to me NICs in my lab, these are supermicro xxv710 based cards and I’m only getting 10g speeds out of them. I did a fresh install of Harvester when I put these cards in, but was only running 10g at that time (waiting for cables). Now I have tried DAC cables and multimode fiber modules, both are rated to 25g. My switch is saying it negotiated to 25g full duplex.
Now I need to check the card to make sure it doesn’t have a limiter set, or check for jumbo frames, or some other setting that could be blocking the speeds. I SSH into one of the hosts, tried ethtool and sudo ethtool and neither works. It seems like ethtool should be installed when I google search, but I’m clearly missing something and doing this wrong. Any help would be appreciated.
