    This is such a great video, an excellent crash course intro "in-a-nutshell" illustration of what's going on with these devices. Thank you, Doug :)

    I can't believe I finally found THE video!!!
    The way you explained VLANs going from the simplest/standard configuration to specific use cases, makes it crystal clear how all of this works.
    Thank you so much!

    It was realy hard to understand the whole consept of taging and vids of ports, the amazing thing is that you managed to explain the whole configuration of vlans in a very simple and easy way to understand. Thank you very much for sharing your knowledge in such an amazing way.

    Very good explanation. I have two Avaya 4548GT-PWR switches on my property. One in my main cabin, an other located some distance away at my tower building, interconnected with fiber. Of course there are PC's in both structures, and in the main cabin, there is access to the internet, via the main switch to a router. As I wanted to send regular data and also some "audio over IP", at each end there are AudioScience asi6685 Live wire cards. I had a hell of a time trying to get this to work, as I'm sure you can appreciate! The solution is of course VLAN, but never having any experience with such, made it not so fun! So I did a search and came across you channel. It has made it clear to me, as how I can get this to work. You're explanations are simple and easy to understand....Many other channels, just over complicated the subject! LOL! Cheers.

    Great video Doug. I am using Allen & Heat dLive incl. Dante, and with the video I will try setting up two switches VLAN with trunk 10Gb fiber, and set up Vlans for both gigaAce (point-to-point, own Vlan), and vlan for Dante, and Vlan for genral network. In theory it should be possible to set up VLAN for the gigaACE between the A&H mixer DM32 and A&H c1500 surface (require level 2 switching). I also have the DT168 dante stagebox. Looking forward to the video with practical configuration of the switches.

      @John Hall Now I have tested this - and it works great! 2 pcs of Ubiquiti USW-PRO-24-POE Switches, devided into 3 VLAN’s (one for data, one for Dante, one for A&H gigaAce). 10GB lc-lc single-mode fiber SFP+ in between (250 meters). All tested, all works fine!

    Dear Doug, thank you! Question, if we are using DHCP Server for each of the Vlan, does it matter which switch is the server? Should the other switch be DHCP client or static? Thank you!!!

      It doesn't really matter what device(s) are acting as your DHCP server(s), as long as there is no more than one per VLAN.

    vlans seem so fun.. i look at all the budget switches on amazon and so many reviews mention how limiting or issues regarding vlan management.. sad. there doesn't seem to be a company that makes a competent vlan implementation in the budget range.

    If I were using the network in your example and my laptop was on VLAN 1 so I can surf the internet, then I need to log into a piece of gear on a different VLAN to change a setup or something. Is there a way to connect from the laptop on VLAN1 to gear on other VLAN?

      Yes, a router is what you'd need. You'll probably want one that doesn't require you to use Network Address Translation if you want traffic to be routed both directions. Most consumer routers don't have that option.

      @Doug Johnson Productions Thanks. So on your network the switches handle it. If not, would you simple put a router between the two VLANs? Would a router between to actual LANs do the same?

    • Doug Johnson Productions
      Doug Johnson Productions  8 ай бұрын +1

      That's where routers come into play. Routers route traffic from one subnet to another. Some layer 2 managed switches have basic routing functionality as well, even though this is a layer 3 function. The rack-mount TP Link switches that I use, for example, can route between subnets, and I use that capability all the time to communicate between different networks.

    HOW do you plug in the router from the venue which you are at? I mean, do the separate addressing systems not cause conflicts?

      @Doug Johnson Productions Thank you for taking time to respond. I'm a little bit stuck. I'm trying to figure out some solutions for my girlfriend's dad. He plays in a band, and wants to ramp up content on youtube for marketing.
      I've heard of PFsense and believe that I could "stumble my way" into getting his video (USB cams to laptop) paired via ethernet/RJ45/1gbps with another laptop (connected to a USB audio interface) which could push via another ethernet cable to my laptop, so that I can use NDI to capture the event for recording and/or streams.
      However, I can't seem to find anything about whether PFsense can operate without internet connection.
      Unless (in the future) I would work toward streaming his events, i'd like to be able to just record the audio & video via NDI, disconnected from the venue's internet. They are only performing in restaurants and birthday parties and stuff for the most part... So, i'm wondering if PFsense could resolve the different laptops internally (without an outside DNS connection to Cloudflare or something).
      Is that possible?
      Please advise, i'm learning as much as I can about Audio Engineering/Networking/Video Production as I can... But GOOD LORD, those are some FIERCE learning curves. LOL 😂😂😂

      The devices I'm using are switches rather than routers. They don't have DHCP servers or NAT routing capability.

    If I'm only using one switch, is the link back to the router still called trunking? And when using a single switch, does each VLAN need its own link back to the router?

    • Doug Johnson Productions
      Doug Johnson Productions  Ай бұрын

      Trunking is the feature that lets you send the network traffic for multiple VLANs over a single cable, between any types of devices whether those be switches, a router, or something else.
      If you need multiple subnets to have internet access (not just one), you'll either need a router which has that capability, or multiple routers (one for each subnet plus one central one to combine traffic from the other routers). If you have a router which supports multiple subnets/VLANs, it would either need multiple Ethernet ports (one per VLAN) or to support VLAN tags.

    So, in order to set it up, you need at least a vlan capable managed switch, a cheap non managed switch simply would not work, even if your router is vlan capable.

    Am i understanding it correctly...
    If I only have the one switch I do not need to use tagging?
    I have similar equip. like pc1, pc2, printer, nvidea shield, and a NAS.
    So 5 vlans, all untagged.
    Sound right?
    Thank you again for the great explanation and any reply you make here....😎

      You could put it on a different VLAN, but you'd need to setup routing between the two VLANs/subnets. Usually we would leave it on the same VLAN though.

      @Doug Johnson Productions Excellent, thank you.
      Does setting the network printer on a different vlan sever the communication or should it be on the same vlan as the two pc's?
      I appreciate the response Doug.

    • Doug Johnson Productions

      You are correct. Tagging is only useful when sending data between switches. You want the tags removed when data is sent to any other type of device.
