I cannot get eth1 to come up at 1000mb. It always reverts to 10mb. I've turned autoneg off and it loses communications with other servers.
I've checked the router port, the cables by plugging my laptop in and it always came up at 1000mb.
I've tried:
ethtool -s eth1 speed 1000 duplex full autoneg on - always reverts to 10mb/full
ethtool -s eth1 speed 100 duplex full autoneg off - loses communication
