Re: [CentOS] hosts fail to negotiate 1000Mbps speed

IIRC, one does not need a crossover cable to connect between two gigabit capable hosts.

Agreed I think gigabit ethernet adapters _have_ to be autosensing of MDI (normal) or MDI-X (crossover) to be considered gigabit capable (ie within specifications). I expect the crossover adapter may be causing enough interference to stop 1gbit from working thus resulting in merely 100 mbits.

This is new information for me.

Furthermore it is entirely possible that it's a 100mbit only crossover adapter: it might not be crossing all 8 lines since gigabit uses 8 lines and not 4 like 100mbit...

I suspect that may be the case here given the above "new" information.
