Hi,

I got a NetXtreme BCM5720 Gigabit Ethernet network card in my server that features two interfaces. Only one of them is recognized and working. I want to configure both in a network bond.

lshw -class network

Does anyone have an idea what I can do to fix this? Might this even be a hardware failure?

Thanks,

We got it fixed. Hard reset and de-energizing the server did bring the network interface back. Just leaving this here in case anyone experiences the same!
