some 10gb ports are able to downrate to 1gb;  that’s a feature of the 
chipset controlling the network interface.
some are notoriously difficult to work with though;   so to answer you 
question, you’d need to know
# what chipset is on the 10gb NIC on your server.  are you able to get 
this information?
# does the vendor allow this to be downrates (so, even though, say 
Broadcom, might make the chip, your NIC vendor might still override its 

can you track down what NIC is in the server?
