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.

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
