This channel has been my spirit animal the past couple of weeks as I've upgraded my home network. Every dang upload is so useful

[indianfarmer]

You are definately my go to channel on tech for networking, storage (FreeNas) and virtualization to mention a few. I recently helped a friend build a FreeNas box which is not my first but this time around I set it up to sync with BackBlaze inspired by one of your videos on that topic. You are perfect for my skill level, not as slow and repetitive as "Eli the Computer Guy", definately not over the top nor spending time on promotions. no bullshit, no nonsense, to the point. You inspire me.

I’ve been following your Virtualisation videos for a while and I’m noticing how much of the same skills I’m using for VMs can apply to how rules within networks function. Thank you Tom for sharing this all.

[agpct]

As much as I am learning, I still like to watch your videos because you bring the practical side to light. Things beyond specs and straight "how to". Your experience and "pit falls" are gold.

[chrisjohnson]

I’ve done a lot of basic networks and had a mild understanding of higher level networking. Honestly you guys make me want to get more and more into this stuff!

[Dreamtwisterk]

Easiest way to digest what a Layer 3 switch does and if I really need one. I'm a network newbie and I'm still trying to grasp some of the terminologies. Thanks for this wonderful video!

[alanmcconnaughey]

A good use for L3 is setting the switch as the default gateway. Then you can swap firewalls, do HA and what not all from the switch. It saves the firewall all the extra routing effort.

0:05:48 'As long as that last octet right here is 1 to 254 it's able to talk'. Now it's quite possible that I could have been confused about your explanation but I do not see a 254 in the graphic. The video was very detailed and you put out a lot in just under 15 minutes. Still I do think that I better understand how a layered three switch or VLAN is supposed to function within a network. Still I'll need to watch the video again; the next time with the transcript running. And this will be very useful for me in my preparation for the A+ exam. So thank you.

[agroleau]

Thanks Tom, appreciate to see real world applications for all these concepts. Very informative!

[MervynMaistry]

Thank you. Informative, educational and interesting. Like a breath of fresh air. The network guys at the company I am using in Berlin are just on another planet and have been unable to explain this as clearly.

[Sladeofdark]

Why are you like the BEST, true-school technologist on the tube these days man? you are like all the guys that taught me I.T. Love your content man.

[aaaa-odwn]

Watched your channel for for at least 3 years now. Always great info from network beginners to network experts. Been very helpful getting my PFsense firewall up and running and integrating it into my home network. I was curious if someday you would review more true enterprise class hardware ie Brocade ICX 6610 Quanta LB6M which have real L3 routing capabilities.

I view layer 3 switches as useful for reducing complexity and time spent administering devices. In the they allow you to remove a device from the chain. Something most people don't seem to understand is they are really a Router with lots of interfaces.

[zeendaniels]

This was most enlightening. Basically, if you need to keep traffic separated, like a guests network incapable of accessing your machines, your NAS and the sort... You don't need layer-3, just a managed switch and access points to go along with your firewall.
I think that's the route I want to go.

[HDuerer]

Interesting, from your previous video I had understood the 10GB switch would slow down for all traffic as soon as it has to do some routing. But if it is only slow for the routed bits but fast for everything else then that's better.
But then we need a video explaining how to ensure the main traffic is not considered routed...

[jimsmith]

Thanks so much for this, clears up some misconceptions for me.

[turboltr]

This was helpful (as usual). I've been doing home networking for 20+ years but struggling to understand the underpinnings of VLANS. When I finally figured it out, I didn't understand why no one seems to mention it when talking VLANs (maybe you did in other videos I haven't seen yet). But the key to my understanding was that VLANs are essentially a band-aid for the lack of layer 3 routing. Even though VLANS are typically combined with subnetting, they are actually two separate things. What surprised me is all VLAN traffic having to go to the router for routing. Wouldn't that not create a huge bottleneck? I assumed the managed switches would route VLAN traffic. Makes me re-think my plan to use VLANs. Or maybe I don't understand as much as I think i do.

[Shiron]

Thanks for that video. I just started to design my home networtk. And the explanation in your video helped a lot.

I would like to make a comment base on experience with networking, electrical modulation of signal and so on.
I used to work for an AV company with home automation systems deployments, we used to configure small to big enterprise networks using different equipment.
Based on our observations we notice strange network behaviour and issues in some of our projects, the common factor was using less then 1 metres network cables between active devices (switch, routers etc). I wouldn’t have any issues showing on the cable tester on anything like that but when connecting cables between active devices we would find the strangest issues in networking. Specifically in the application level things would not work, at first glance and investigating everything will look normal. Tried changing the cables thinking must be a faulty cable with the measure same problems. Once we put at lest one meter of cable between them problem sorted in a instant.
Further more we verified with engineers in electrical field explaining to us why this was a problem.
