Important Commands: Ping - Tests connectivity between computers config terminal - Enables the configuration terminal int - Enters the interface of a certain device switchport - Allows you to configure ports on a switch ip address - Enters the IP address and subnet mask of a port encapsulation dotq - Connects a VLAN to a router port

Important Concepts: The use of VLANs in order to connect devices, and of a router to connect VLANs

Important Things to Note: VLANs, or Virtual LANs, are layer two devices that enable devices to be connected, even if they are connected to separate switches, working in a similar way to normal LANs. Without a router, VLANs may not be interconnected. In Packet Tracer, you can enter VLANs and assign them to ports in the "config" section. The router on a stick setup, where you pipe traffic from the router through a single switch, is an efficient way to connect the VLANs to one another.
