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.
