One of the questions I’ve asked myself when troubleshooting SPLAT-installations were “What NICs are in this box?”.
Seeing how it is built on RHEL the answer wasn’t too difficult to find, but I’ll put it here nontheless – just in case someone stumbles along looking for the answer to that exact question. =)
The command “lspci” will provide the information needed. The command without any options would give a similar list to the following example taken from a fairly new installation:
[Expert@FWF01]# lspci00:00.0 Host bridge: Intel Corporation X58 I/O Hub to ESI Port (rev 13)
…
02:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)
02:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)
03:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)
03:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)

0c:00.0 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet Controller (Copper) (rev 06)
0c:00.1 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet Controller (Copper) (rev 06)
0d:00.0 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet Controller (Copper) (rev 06)
0d:00.1 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet Controller (Copper) (rev 06)
…
10:00.0 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet Controller (Copper) (rev 06)
10:00.1 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet Controller (Copper) (rev 06)
11:00.0 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet Controller (Copper) (rev 06)
11:00.1 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet Controller (Copper) (rev 06)
From this example we can see, what appears to be, three NICs.
A more verbose output gives us some more information, which can use to deduct the NIC models. Nifty, eh? =)
