With the switch set to 10 Gbps FDX, this command on the server gives an error: # ifconfig ix0 media 10Gbase-SR ix0: Invalid media type! Then I tried: # ifconfig ix0 down # ifconfig ix0 up Then it worked. 10G. I moved the cable back to the original 10G transceiver where it was doing 1G. That went to 10G. Auto-negotiate is not needed. Just the up/down to reset the NIC. All good now. :) Thank you. -- Dan Langille dan@langille.org
