Adding a 2nd NIC after installation

Post by Jasondaro » 2019/07/12 21:47:31

Hello guys,,
I did a minimal webserver install on CentOS 7, using the built-in network card in the computer I'm using.

After the install, I added a 2nd network card, an Intel 82574L.

Running lspci sees both the Intel card and the built in Broadcom, but ifconfig -a can't see it.

What do I need to do to get this 2nd NIC functioning and fully recognized by the system?

Thanks

If you still have a chance to return that card, I would. The 82574 is by far the worst card that Intel ever made, nasty hardware faults sort of barely covered over with firmware patches. Chances are that to make it work reliably in linux you'll have to disable pcie.aspm via the kernel command line.
The future appears to be RHEL or Debian. I think I'm going Debian.

CentOS 5 and 6 are deadest, do not use them.
