Unhappy How to find about NICs installed
Hi;
Is there a way to determine for sure how many NIC ports installed on my Linux box?

I tried to run "lspci" but not sure about the results, it's not clear.

Below are the results when i run both "ifconfig" & "lspci" on my Linux box i hope someone can help me finding the actual numbers of NICs installed:

Is it 2 ports or 6 ports?


Code:
server01:~ # ifconfig

Seems your box has 6 ethernet adapters. How many ports they have and which are onboard or not etc. you should have a look yourself at your box maybe.
ifconfig shows configured interfaces. It does not necessary show all NICs.
