I"ve not used the QFX but the ACX5k is based on this same chassis and has similar flexibility with ge/xe port options. You do configure the port namge ge/xe to match the SFP speed inserted. These can...

Hi yes, we did check that info; in fact i believe only the link-mode is allowed to be changed for the 1Gb option, but not the speed. these ports are meant to be 3-speed 100/1G/10G we're not using any...

Sorry as well, as I also missed the fact that this was a 48T -;( You should leave auto-neg enabled, and if your servers are coming up at 100M full, it would appear that is what they are negotiating to...

Did you open a ticket for this one? It feels like a bug that should be in the PR database. But I don't see it there yet. They should get that patched.

Looks like at some point in time auto-neg got disabled, as it should have been on by default. Smicker's change was just to enable auto-neg. To work as 100/1G/10G TX auto-neg must be enabled.
