Ethernet

Ethernet is a family of computer networking technologies commonly used in communication devices. A scheme known as carrier sense multiple access with collision detection (CSMA/CD) governed the way the devices access the channel.

• Speed: 10 Mbit/s, 100 Mbit/s, and 1 Gbit/s

Activities

1. Configure an Ethernet connection in Ubuntu Linux using netplan or nmcli in RHEL depending of your Linux distribution.
2. Configure Ethernet bonding connections (802.3ad / LACP link aggregation)
3. Show interface configuration in Linux including ip addresses: ifconfig -a or ip a
4. Show interface ethernet network capabilities of network interface in Linux, such as speed, with: mii-tool -v YOUR_INTERFACE_NAME, mii-tool -v eth0
5. Read about wikipedia:Jumbo_frames: ip link set dev eth0 mtu 9000
