    I liked how the picture of the 2 separate LANs with their own switch, merged both switches into 1 switch, while still maintaining 2 separate LANs

    I had to go through a ton of YouTube videos with East Indians with strong accents and useless information before I found this useful, articulate, well produced presentation. Thank You! This video needs to be atop the YouTube search algorithm.

    I like your explanation of Vlans and the way you use examples.

    You could also do a follow-up video for us noobs who might be confused as to the difference between a VLAN and a subnet. since they sound very similar.

    Let's say I have a 5 port switch. In the switch I can assign different ports to different VLANs. How do I connect that switch to a Linux PC's single eth0 port and break it out into the different VLANs, giving me eth0.1, eth0.2, eth0.3 and eth0.4.. Effectively giving the PC 4 ethernet ports?

    If any device can be connected to any VLAN whats the Purpose of a VLAN? Is it that the traffic is still separate? Would that mean that every switch has to be set up exactly the same?
