I usually do one of two things. Depending on the situation. If both NICs are from the same vendor I install mii-tool and only plug in one port. mii-tool will show link state. This when it negotiates it will show output like:
eth0: negotiated 1000baseT-FD flow-control, link ok eth1: no link If the NICs are from different vendors I usally just do a ifconfig and grab the MAC addresses of the cards. Then I Google for a mac lookup tool. The first 6 digits of a MAC are vendor specific. Hope this helps! Colt On Fri, Nov 12, 2010 at 7:51 AM, Stefan G.
