I have a system with a 2 port Intel I225-V 2.5Gb card in it. (Interface igc0 and igc1).
I am currently using igc0 as my WAN interface to my 2.5Gb fiber service and it is working great. I recently got a second ISP and I am trying to connect it to igc1. No matter what I do I cannot get the NIC to even light up.
- I have checked the cable by using it in igc0.
- I have tried several devices and several cables, no luck.
- I know it is not a firmware/driver issue as I am currently using an interface on the same card.
- I have the interface enabled, speed set to 1000 (just to be safe).
It feels like the interface is 'administratively down'. The only other explanation is hardware failure, but I find that a bit hard to believe. I've never had one port on a multi port NIC fail personally.
Any other things I should be looking into?
