 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++    ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ : Networking : From Linux perspective : Networking : Switching How does system A reach B , we connect them to a switch and the switch creates a network containing the two systems . To connect them to a switch we need an interface on both the nodes. Physical or virtual depends on the host.  To see the interfaces for the host we use the IP link command . In this case we will see the interface called eth0 that we will be using to connect to the switch. In this case we see an interface named eth0 , that we will be using to connect to the switch . Lets assume is a network with 192.168.1.0 We then assign the ip addresses to the systems on the same network.  For this we use the command ip addr , once the link is up and IP Addresses are assigned. The computers can now communicate to one another through the switch ...
