Looking for a simple method to identify the physical port linked to a specific NIC ID? In VMWare, it's marked as NIC-5, but that doesn't help us since the port isn't labeled.

NICs are usually organized based on MMU/PCIe connection paths. When you have two dual-port NICs, the one in the lowest PCIe slot number is labeled NIC1 and 2. It’s easy to plug in a cable and see which port is active, helping you determine the grouping. Cross-reference this with MAC addresses for accuracy. For instance, a server with an onboard quad port 1Gb NIC and two PCIe dual NICs typically shows NIC1 through NIC4 as internal, while NIC5 and NIC6 are the first PCIe NICs, and NIC7 through NIC8 are the second.

I hope that's it. We have an issue where all of the cables are plugged into all of the NICs and if we unplug one cable it's going to take the whole production environment offline. I'm going to try looking at it that way with the MAC addresses.

It seems unusual, usually we handle NIC teaming instead. Having so many separate connections makes it hard to see why teaming or VLANs would be chosen.
