I can not disable the auto-negotiation (eth1) on my centos 6.2 via ethtool or /etc/sysconfig/network-scripts/ifcfg-eth1
Autonegotiation is mandatory for 1000BASE-T as both sides have to work out which pairs they are going to use. Check: 1)cable 2)switchport if those are ok then you probably have a driver/NIC problem
Two more things: a) make sure the router/switch isn't pegged or being changed to slower b) are your cables ok for gigabit. I know this sounds absurd, but I, personally, have changed cables, and it made the difference
Thanks, but is a remote-server, the server is in another datacenter. I can not change or check the cables/switch - and the stuff in the datacenter is not very usefull. I'm hoping to solve the problem with disable the auto-negotiation.
Hey - I was assuming it wasn't under your control, any more than mine, here at work, are under mine. When I have this problem, I file a ticket, and eventually get to talk to the admins who *do* have control over that. And yes, too many times, I get a "oh, it is pegged, I have no idea how that happened...." from them before they fix it.
