love how we've had ethernet link-speed autonegociation on 10M/100M/1G for decades but fucking SFP+ can't autoneg between 1G and 10G (not to speak of 40G and 100G) like...

@wxcafe
That has nothing to with the sfps. More likely it has something to do with cisco. 10GbE SFPs can be programmed to do 100/1000/10000 and even Fibre Channel.

@wxcafe @franzi to be fair, 10/100/1000 autoneg also isn't the epitome of reliability.

@wxcafe it's frequently a problem between switches, not even necessarily with different vendors, but I've also had servers, desktops and laptops where I had to disable autonegotiation.

@lexi huh. I've never had a problem with anything that supports 10/100/1000, only with stuff that supports 1G/10G/up.
