I've tried resetting the SMC switch to factory defaults (with auto-negotiate on). I've checked the /etc/beowulf/modprobe.conf and it doesn't seem to be demanding anything exotic. We've tried swapping out to another SMC switch but that didn't change anything.
No idea really, as I don't use SMC switches. First thing I would do would be to get a laptop with Linux on, and attach it to the SMC switch. Configure the Ethernet interface to use DHCP, then ifconfig it down then ifcoinfig it up. Run tcpdump eth0 as you do this, and tail -f /var/log/messages If it gets a DHCP address (and of course on the cluster head node there is a pool of free DHCP addresses configured) the test tftp file transfer. Set the tftp daemon on the head node to run in debug mode, and start it up. Try a tftp get of a test file on the laptop.
