Fangtooth Mellanox Connect-x3 speed issue

If you need failover you could look into link aggregation/LACP.

I am not well versed enough to speak on what the possible caveats but if you’re lucky one of our community experts will take note and chime in…

Thank you very much! I will play around with it. This at least solves the speed issue. I did not know that you couldn’t have more than 1 connection. But that makes sense why it degraded to the slowest link speed.

There’s this in the official docs:

Link aggregation requires a managed switch that also supports it, and is set up correctly.

Edit: Be careful when playing around with this as to not lock yourself out. Have a keyboard/monitor attached so you can reset the network if needed. + Save a config!

Thanks! I’ve updated my bond0 to FAILOVER with the Connect X-3 card in the first position. Seems to be working.

I don’t know how failover handles interfaces with varying capacities, cool if it can make the most of it.

Good luck!

Edit: Some quick googling suggests identical interface capacities are expected/required with LACP. That was some quick googling indeed though. Maybe I’m hallucinating.
