So each port on the server/host must be on a different subnet? 192.168.1... 192.168.2...
and so on? Also when you define NIC do you mean each individual port or the chip/card itself? In other words, is our Intel x520-DA2 (card with 2-SFP+ ports) one NIC or two? Thanks for the fast responses everyone. On Mon, Jan 21, 2019 at 4:08 PM Marcus D.
