If you are running Intel NIC(s) such as the X520-DA2 with 3rd party optics =
for something like DWDM, there are driver option flags for linux/windows, e=
tc to permit the use of the optics. In deployments we've used various brand=
ed dac cables to connect Intel branded nics to cisco/arista/brocade, withou=
t issue.
As with any vendor, there is a work around procedure.=20

I've heard from people running Intel NICs and HP switches, that this can't =
be turned off there. You run into very interesting problems when you're try=
ing to use DAC cables between multi vendor.
Any pointers to how to turn this of on Intel NICs and HP switches?
