Show List Of Network Cards on Linux
lspci command : List all PCI devices.
#lspci | egrep -i --color 'network|ethernet'
#lspci | egrep -i --color 'network|ethernet|wireless|wi-fi'
lshw command : Linux identify Ethernet interfaces and NIC hardware.
#lshw -class network
$sudo lshw -class network -short
dmidecode command : List all hardware data from BIOS.
ifconfig command : Outdated network config
$ifconfig -a
$ip link show
$ip a
ip command : Recommended new network config .
$ip a show wlp82s0
$ip -br -c link show # To list all interface, link status, MAC address, etc
$ip -br -c addr show # similar list with IP address instead of MAC Address
hwinfo command : Probe Linux for network cards.
$sudo hwinfo --network --short
ethtool command : See NIC/card driver and settings on Linux.
$sudo ethtool -i eno1
$sudo ethtool -i enp0s31f6
/proc/net/dev file
The dev pseudo-file contains network device status information. This gives the number of received and sent packets, the number of errors and collisions and other basic statistics
$cat /proc/net/dev
Failed to set iommu for container: Invalid argument
A VM configured with a vGPU that supports SR-IOV may fail to start, This issue occurs because PCIe AER [Advanced Error Reporting] support was disabled in the BIOS settings of the server.
