We have some Dell PowerEdge 1950 1u rack servers with GigE NICs on them running FreeBSD 6.1. The NICs are connected to a Cisco 24 port 10/100 switch. The interfaces are down when the programs that are running on them are dormant, and whenever they receive a job, they bring the interface up. (The other NIC is always up, which is how the servers receive new job notifications.) A couple of times per day (about every hour or so on average), the server receives a job, brings up the interface, and starts processing. The thing is that occasionally, about 10% of the time, bringing up the interface doesn't seem to do anything. It's as if the network is still down. So we have to go any manually bring it up again for it to work. We assumed that it was an auto-negotiation problem with the GigE card and the switch, so we forced everything to 100Mbit, but it still occurs. What could be the problem? thanks, Thomas
