This command will list the interface status, MAC address, MTU size, etc.
The number next to link/ether is the MAC address. The second way to find MAC address is using “ ip link show” command. TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0ĭevice memory 0xb1960000-b197ffff Find MAC address with ip link show command in Linux This command will list network interface name,Ip address, MTU size, etc. I want a bond to always use the same MAC address. The number next to ether is the MAC address. How can I change the MAC address of a network interface I want to persistently set a specific MAC address for the NIC. All we need is to open the terminal then type ifconfig -a in the prompt. The best Linux command to find MAC address is using ifconfig command. Find MAC address with ifconfig command in Linux 00:1B:44:11:3A:B7 is an example of a MAC address. MAC stands for Media Access Control, and each identifier is intended to be unique to a particular device.Ī MAC address consists of six sets of two characters, each separated by a colon. 1 External settings of the virtual machine 1.1 Network adapter mode setting 1.2 Get the MAC address 1.3 Set subnet IP 1.4 Does the VMnet8 IP information of.

If you have any questions or feedback, feel free to comment below.From Wikipedia, A MAC address is the unique identifier that is assigned by the manufacturer to a piece of network hardware (like a wireless card or an ethernet card). In this guide, we have shown several examples to verify network interface information such as available interface, active interface, NIC’s IP and MAC address and network interface port speed on Linux. Run the below shell script to check all the required information about the network interface: # sh /opt/scripts/nic-info.sh When you run the IP command without any argument, it gives you plenty of information about NIC, but use the following customized IP command to check only the network interfaces available on the system: # ip a |awk '/state UP/' # ethtool eth0 1) Checking available network interfaces

The ethtool command is used to query or control network driver and hardware settings. Valid_lft forever preferred_lft forever What is ethtool command? mode2 (balance-xor) XOR policy: Transmit based on (source MAC address XOR'd with destination MAC address) modulo slave count. The primary option affects the behavior of this mode. Inet6 fe80::f816:3eff:fea0:7d5a/64 scope link The bond's MAC address is externally visible on only one port (network adapter) to avoid confusing the switch. Link/ether fa:16:3e:a0:7d:5a brd ff:ff:ff:ff:ff:ff Edit the /etc/network/interfaces file and add in the following variable line to the appropriate section so that the MAC address is set when the network device. # ip aġ: lo: mtu 65536 qdisc noqueue state UNKNOWN IP command is similar to ifconfig, which is used for assigning Static IP Address, Route & Default Gateway, etc.

In this tutorial, we will show you how to check the available Network Interface Card (NIC) and other details such as interface name, associated IP address, MAC address and interface speed. If yes, check other configuration details that are compatible with existing interfaces. Server primary interface would be configured as part of the server build activity, but sometimes you may need to configure an additional network interface in Linux for several reasons.Īn additional interface will be configured for network bonding/teaming, high availability or a separate interface that is used for application requirements or backups.īefore adding a new interface, check if the system has any free interfaces.
