VLANs can be used to create a separate of broadcast domains on a single switch. In this video, you'll learn about VLANs, 802.1Q trunking, and managing both voice and video across the same connection.

Clear and to the point

[@vladislavkaras491]

Thanks for the video!

Lol, I was literally setting up my home Internet with vlans before I saw this

[@LiamoverIP]

How does separating VOIP and data into separate VLANs improve performance if they are still travelling the same connections/devices? Wouldn't congestion affect them all the same?

[@pleasantvegetable]

There's a lot of data that gets broadcast around a network (ARP as the most obvious example) and reducing the number of hosts that gets sent to helps a lot with reducing the amount of data that is even on the network to begin with, but I also imagine at least part of the point is to have the different broadcast domains line up with IP subnets, and have each subnet go to a different router.

Is this something that's practical for an average home internet user? I have a 16-port switch that I just plug all of my stuff into. That switch is connected to the router, which is then connected to the modem.

[@RoelandJansen]

If you are not separating traffic, have a single bcast domain... Skip it

@@RoelandJansen Thanks, Roeland.

@@alideew5493 exactly. And people that know will do that.

Hi professor messer, does trunking involves connection and communication with different VLANs (like in example you explained vlan 100 and vlan 200 on switch 1 and other was also the vlan 100 and 200 with other switch, so can vlan 100 and 200 on one switch communicate with vlan 300 and 400 of other switch using trunk?) or just same VLANs apart

[@chrisschatz4670]

From what I understood, trunking is combining multiple connections into one connection, removing the need to connect each network with individual connections. Like when roads merge into a highway then you merge off the highway and proceed to your destination. If that helps.
