You shouldn't have to do anything at all for it to behave correctly. I'm
assuming both NIC are 1Gb. Connecting one to the 100Mb switch/router will
result in the NIC running at 100Mb. Connecting the other to the 1Gb switch
will allow the NIC to run at 1Gb. The only circumstances which would result
in the NIC running at a slower speed while connected to the 1Gb switch is
having an ethernet lead that is too long. The characteristice capacitance
and inductance of the ethernet lead increases as the ethernet lead
increases. This basically means that high frequency communications suffer
from distortion and the NIC or switch will automatically attempt to
successfully communicate at lower data rates. Standard switches will support
1000/100/10 Mbits/s so it will try those three modes starting at the
highest. If the lead is longer than 100m, it will not work at all.
If your server is running a DHCP with all the clients connected to it on one
NIC and the other NIC connected to your internet gateway/router/adsl modem,
you should always have your clients connected to the 1Gb switch as none of
the 'bottom bracket' routers/gateways/modems run higher than 100Mbit.
