You. Are. Awesome! Sooo much experience being taught in this series, Jeremy! I am truly loving the journey in spite of being a long-timer in the field. Thank you for sharing your art with us. You are inspiring!
I think another item to consider when getting into medium sized deployments is the mix of non-POE and POE switches. Of course you want to determine power budgets for APs, phones, etc. but then likely have some other switches for non-POE drops too...thoughts on POE planning for medium scale deployments on up?
I appreciate how you tell us in most of your videos, all the shortcomings and difficulties you have faced in your years of experience and as a bonus, you give us troubleshooting tips which is invaluable. Thank you Jeremy, YOU ARE AWESOME!!
21:33 I did an help-desk internship for an elementary school and this was a similar MDF, IDF layout for the school. So informational seeing you explain all of this. Thanks
I normally have 2x 48 port Layer 3 switches at the top of the Main Stack and then run 2x or 4x 1Gb LAG (EtherChannel) Groups between each switch back to them. Let them control all the vLANing, internal Routing etc LAG Groups rock. I still have that habit of using a different brand Firewall/Security Device/Router to my switches. I like Sophos UTMs and Ubiquiti Networking :) Starting to transition to Ubiquiti 10Gb ES-16-XG switches as Aggregation Switches now as prices tumble down for 10Gbe.
You the most energetic and passionate teacher. I have ever come across, who always feel excited about explaining stuff even if it's repeating the CCNA training 100 times your consistency is just beyond amazing. Please keep up the good work. Your CBT training are the only video training that keeps me awake during the whole length.
Jeremy thank you for this. I am starting my journey into networking and this opened my eyes how much fun this will soon be. It’s like a big puzzle and I keep getting more and more excited. Thank you for these videos. I cannot express how much this helped me
ahhh man this video is so good!!!!!!!!!!! LOL I've been studying A+, Network+, Security+ and I haven't even come across this information yet of how to architect a Network system within a building. This was amazing. didn't know about MDF or IDF, etc. Get that Principals room out of there lol. Great Teacher.
Thoughts on stacking the core switches? You get your redundancy and don't have to deal with stp as you'll just port channel 2 access switch links to the each of the core switches.
Hey, great video. I like your enthusiasm as always, how things are explained. What about the approach with a stacked core and fibre connections between core and access switches? Cleaner design, saves copper ports, no crosstalk, no 100 meters ethernet limitation etc. Just a superficial concept, there is of course a bit more to it. That is basically what I was confronted with when I went out to the real world with my fresh CCNA in my pocket some years ago and oh my. Reality hits you hard and merciless. If I did not missed it, a video about that would be awesome for those who don't know that yet. I saw a question here asking what if 100 meters are exceeded so this would be a good answer to that. Of course, this might be a bit too much for a small size office but there are good chances to have it for other setups.
Hi Jeremy, awesome teacher, lots of love. A question, can we use etherchannel to connect all switches together ?, and be rid of loops? Anyones input appreciated. Thanks.
You can, you would have to modify your MDF/IDF set up a little bit though. Unless you wanted to just use EtherChannel say between MDF-SW1 - IDF-SW1 and MDF-SW2 - IDF-SW2. However, that still would have a loop between SW1 and SW2 and STP would still block a link in specific Vlans depending on your STP setup. You could also just run all the cables from MDF to IDF on SW1 on both ends, and LAG them all there, then you wouldn't have a loop. But, you would have a single point of failure if SW1 in either closet went down. Personally, if we were using 48-port stackable switches as Jeremy said, I would have stacked the switches in the MDF and IDF, then ran the 4 L2 cables in 1 LAG between the closets to get 4gbps of bandwidth and in that case, we would have been rid of loops as you suggested, as well as gain bandwidth from the LAG and freed up switch ports on the front of the switches by using stacks.
This is important, because today most all switches are L3. I would move away from L2 spanning tree "flat" topologies and move to a L3 IP addressing scheme. In my sketch I would put a L3 switch n the MDF as a core router and each IDF is a separate IP subnet. Place IP helper addresses on the MDF L3 interfaces facing the IDF switches and use a few static routes for this small trivial network.
WOW!!! Nice video. Almost went back to my office and re wire everything but than i remembered nope about 600 clients they gonna get mad if only a minute of no internet (thanx Covid 19 everyone using the internet)...
In some places you say that you can’t create a LAG with links from different switches - but this is not completely true, we have vPC for this (or MLAG.. or whatever other vendors call it)... maybe not a CCNA topic but it’s worth mentioning
You. Are. Awesome! Sooo much experience being taught in this series, Jeremy! I am truly loving the journey in spite of being a long-timer in the field. Thank you for sharing your art with us. You are inspiring!
Thanks so much Roger, that means a lot! I’m glad you’re enjoying the series so far - comments like this are the reason I do what I do! :)
That is amazing, there is no other series like this using examples from real life .. thanks Jeremy.
That’s not actually true there are other IT pros do same thing.
One word , Jeremy you are the best !

Thank you! 😃
Uncle Jeremy, you are doing a very fantastic job for the community. May the good LORD bless you always.
Thanks Jeremy, I am 25 years doing this and that was the best concise explanation I have seen
I liked the real-life project. Thank you Jeremy.
I'd love to spend a day shadowing Jeremy, the things I'd learn. I would even work free just for the knowledge, great stuff!!!!
Jeremy thank you for this. I am starting my journey into networking and this opened my eyes how much fun this will soon be. It’s like a big puzzle and I keep getting more and more excited. Thank you for these videos. I cannot express how much this helped me
In school network I would add two more L3 stackable switches as aggregation layer,total 12 switch
Thank you Jeremy you always amazing as usual
Thank you for sharing your experience and what is network engineer actually doing. Amazing tutorial! Can't wait to watch the next episodes!
Great video! I would also think about Stacking the access switches together. Pros would be to save ports.
Many Thanks Jeremy!
this is how i lab this channel Jeremy explain well how this stuff work in more realistic.

This is a great series. Keep them coming!

This simply amazing. You're my Master Sir. Love from Sri Lanka.

Great summary.
You are the best of my 2020 Take that principal out of there lol 😂
Great lesson here! Thoroughly enjoyed that one.
In my organization we typically use wiring closets as IDFs and MDFs.
Excellent refresher !!!
Wow you're an amazing teacher!
Love you Jeremy
So good! Thanks for sharings this kind of videos !!!
❤you're the best man !
Thank you so much Sir!
Awesome.....

@@mattpatrick986 Thanks for your input 😊
Do we need distribution switch for this design?
Do network cable still work after the flood?
10G SFP+ for uplinks 🥰
I want to know when will be time to upgrade core switch to L3 switch? Do we need two cable to each core switch?
This is important, because today most all switches are L3. I would move away from L2 spanning tree "flat" topologies and move to a L3 IP addressing scheme. In my sketch I would put a L3 switch n the MDF as a core router and each IDF is a separate IP subnet.

@@MrBraveheart814 why don't use ospf instead of static roles, since you are configure routes for multiple l3 switch?
WOW!!! Nice video. Almost went back to my office and re wire everything but than i remembered nope about 600 clients they gonna get mad if only a minute of no internet (thanx Covid 19 everyone using the internet)...
Get a 2nd pair of hands then you'd be down to 30sec of no internet
Around 7:40, what about vPC
what is vpc?
In some places you say that you can’t create a LAG with links from different switches - but this is not completely true, we have vPC for this (or MLAG.. or whatever other vendors call it)... maybe not a CCNA topic but it’s worth mentioning
Love the video though, very useful with real life examples for junior/aspiring network engineers!
First!!
I cringed every time you said "boiler room", worked on telephone and network equipment mounted in the filthy steaming boiler room too many times.
Where is the Episode 1 and 2?
