Lshw -c network -businfo

The command line tool Collecting hardware information with lshw and inxi under Linux (list hardware) shows hardware information on a PC or server. In this article, we explain how to get an overview of installed network cards, its PCI-addresses as well as device names with lshw -c network -businfo

lshw -c network -businfo

The following output shows network devices of a Lenovo Thinkpad X230. In this device, an Intel 82579LM Gigabit-Ethernet controller as well as a WLAN module is built in:

werner@x230:~$ sudo lshw -c network -businfo
Bus info          Device     Class          Description
=======================================================
pci@0000:00:19.0  enp0s25    network        82579LM Gigabit Network Connection (Lewisville)
pci@0000:03:00.0  wlp3s0     network        Centrino Advanced-N 6205 [Taylor Peak]

The next output shows a server with an onboard Intel I350-T2 Dual-Port Ethernet chip as well as multiple Broadcom network cards:
