    Thank you so much for this video, it cleared up a lot of confusion about why we would need to configure several VLAN-s on one switch.

    That was a fantastic explanation, and it's exactly what I needed to know. I have a large number of smart devices in my house, and I'm starting to run out of IP address. I'm running an Opnsense router, so now I just need to learn how to segment smart devices to 192.168.2.x, computers to 192.168.1.x, game consoles to 192.168.3.x etc. while allowing them to still talk to each other like they're on the same LAN. I know Google Home says it has to be on the same network as the devices it controls, so I have to figure out how to do this so my phones can connect to wifi on the 1.x network for example, but still detect and control devices with 2.x addresses. Off to the search bar I go!

    This video was great. I wish you had a VLAN video explaining the difference between tagged, untagged, excluded, forbidden ports for VLANs. Very confusing.

    Technically these are each a private non routable networks and not subnets unless you configured them other than /24. After that this is a great way to describe this topic.

    Hi great video and explanation. I have one question, how do each of the VLAN use the router to connect to the internet, considering they have x3 separate VLAN / NETWORKS ?

    • @screen-o-matic
      @screen-o-matic 5 років тому

      Each VLAN subnet would also be built on the router, by allowing only some or all VLAN tags (the street in this scenario) to pass traffic to the Internet on the router. Any traffic not matching those permitted VLAN tags would thereby not be permitted Internet access. You could use this capability to restrict Internet to certain devices on the network as well! Of course, the router must support multiple VLANS in itself, and can also be the source of other services, such as DHCP for each VLAN subnet. Robert may be able to explain better and there may be another video showing this functionality.
      In that setup, your layer 3 switch also acts as a psuedo-router in that it allows or forbids certain VLANs from accessing individual switch ports, essentially breaking one switch up into several smaller switches for each subnet. It's all really cool stuff and very useful in any networking environment.

    I need ideas on setting up 4 VLANs. 1. For main computers, one for IoT devices, one for my guests and finally one for my Web Server to isolate it from everyone. Current my default gateway is 192.168.123.254. Subnet mask is 255.255.255.0. The web server is static on 192.168.123.104. How would you build the VLANs on a Cisco SV260w router?

    • @techpub
      @techpub  4 роки тому +1

      After creating the vlans, you then need to apply them to each port. You will need a router to route the traffic between vlans unless you have an intervlan router which I'm not sure if this is. I will add this to my list but too hard to type it all here.

    Vlan tag attached and detached on which port ? Access or trunk ?

    • @techpub

      No vlans attached to trunk ports. Only switched access ports.
