The issue is not a big deal but one we would like to solve. we have no way of signaling an upstream router that a path is down but via turning off the link of the ethernet port. This would only be used when something goes wrong. The hope is that we could automate some problems and handle other situations remotely avoiding having to visit the system in person. > > Any thoughts? We can modify the system so if it means modifying the driver or some other code, I am willing to try. Just need a little direction. Marius talked about doing this. Maybe it's time we added it as a device option, so people can have the PHY disabled when the NIC is brought down? Adrian
