"Could the auto-negotiate depend on the order in which things are turned on?"
In a decade of working intensively with speeds of ethernet, I have never seen this to be the case. Auto-neg is a sold standard that has been very well tested and implemented. Any network device made in at least the past 15 years should default to auto-neg on. With that being said, if there is a cabling fault or a NIC is failing that could certainly cause two net devices to not auto-negotiate. It's really easy to check eth speed/dup/auto-neg on the linux box side with ethtool: ~$ ethtool eth0 Settings for eth0: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Supported pause frame use: No *Supports auto-negotiation: Yes* Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Advertised pause frame use: Symmetric *Advertised auto-negotiation: Yes* Link partner advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Link partner advertised pause frame use: Symmetric *Link partner advertised auto-negotiation: Yes* Speed: 100Mb/s Duplex: Full On Thu, Jul 31, 2014 at 6:22 PM, Bill Barry <b...@billbarry.org> wrote: > It could be as Neal suggests an auto-negotiate problem.
