I am designing an introduction to networking course for learners with no prior knowledge of networking. Nor do I have any prior knowledge of networking! Your videos have been extremely helpful in helping me to grasp the basic concepts the networking - indeed, they are easy for anyone to understand. I am using quite a few of your videos to impart this knowledge to novice learners throughout the course, as I believe they are an excellent learning tool.... so thank you!
I'm familiar with VLANs and I know how to configure them. but it is the first time to understanding them like this. thnx from my heart. the way of explaining things through scenarios is amazing.
BRUH!!! I cant tell you the amount of notes I have on this stuff and I still never understood them am so grateful for finding your vids really, I have just registered on your website I cant wait for your CCNA COURSE am now prepping for N+
The quality of the content you guys serve cannot be quantified. It’s a goldmine, and it’s really helping a lot of people. Thank you so much for the effort put into this ❤️
It only taken me a short few hrs to watch half the entire CCNA Playlist. Even stopped to read a few comments and answer some questions. So I now know I can watch the entire playlist in an evening and will do so again this weekend in preparation for my CCNA exam next week. Thanks CertBros for the curated compiled list to make a speed review watch list.
Thanks, love the way this was explained. Installed OpenWRT on my router so I could use vlans. Just by watching this video configuring my router with a vlan and tags suddenly became easy, while before I didn't understand any of it.
This is by far the best Video on VLANS or Networking Concepts that i have ever seen. Trust me when i tell you that i have searched HIGH... and i have searched LOW... My friends this is worth your time, and definitely your support! Thank you for putting this out there! p.s. me llamo SURE SHOT!!
You are crushing it with these videos. So simple and clear. Well taught and you make everything just "click". Excellent job. Keep making vids like these and you're channel is going to explode > 1 million subs! Cheers
All your Videos are excellent ....No need to read books ..Just we chack check these and revise the knowledge we have ...Good work ...want to see many more Videos ..
Yeah it is. I follow Jeremy IT Labs on TH-cam. Did his full CCNA Course on Udemy online. But I also like CertBros animated vids. So I’m currently watching his entire 31 video CCNA playlist as a speed review as I have my CCNA Cert exam next week.
fun little story to remember VLANs imagine you're hosting a party in your room in your family apartment, and you don't want your parents to find out how many guests are invited so you open up your window and let people climb up for security your best friend acts as the bouncer and checks the IDs XD
you seriously do have great teaching skills your every video have crystal clear explanation...love and respect from nepal as well...looking for more videos in next few days.
The videos from cetbros are really tremendous. The most of the topics the way you explained was awesome. The people will love and start learning who doesn't have idea or interest in Networking !!! . We are really awaiting for more tech videos !!! Appreciate your great works
When is the full course coming because this is without a doubt the best collection of videos on ccna I’ve have been able to find. You somehow manage to explain everything in a way that just makes sense and then just when I have a question in my head the next part is you answering the question! Amazing work! I hope the full course comes soon
if it broadcast packets on all ports besides one that it received packet from then thats not switch but an hub but switch will act as hub until it learn mac addresses
hey, a little question in 3:39 you show a lan network seperated by VLANS and every department has 20 pc's theoretically. but in reality if i wanted to have 3 departments of 20 pc's each wouldn't it require an extra switch?(assuming i'm using a 48 port switch)
Hardware wise, you do indeed need another switch to carter the total number of PCs. You can trunk the switches as mentioned in the video to allow the same VLAN traffic on different switches.
9:56 in this example, should the VLAN of the computer connected to the interface assigned to VLAN 20 also be changed to 20 in order for it to work? How do you do that?
Great videos... much still goes over my head. In one of your video you mentioned using vlans to separate different devices bease on trust level... highest level for PC you have and lowest for noname bulbs etc... Does that mean you are assigning IP statically for each device? I'm trying to figure out how I should do this. And expand on it to limit access to some devices if access remotely via VPN... I'm using an old 3com 4500G Switch.
Small note: i think saying "the TCI contains 3 bits of information" is misleading, as "bit" means something. Had to double check elsewhere, but it's actually 16 bits.
So what if devices on different vlan want to communicate? Would they still be able to do it as if they are on the same network? Or if there any special settings to make it happen?
They can communicate. A communication frame gets sent for example on VLAN 10 from your PC via the Switch and it get sent to the Router. At the Router it repackage the communication frame from VLAN 10 and then sends it back down the network on VLAN 30 to my PC on VLAN 30. The Router is who decides for inter VLAN Traffic as a L3 - Layer 3 device. Some Switches or more advanced Switches are Multilayer Switches as L3 and have the capability to route inter VLAN Traffic.
And I though Tony Stark was my favorite superhero … you are my new #1 I’ve been looking at too much info and this is the first time this has been explained where it finally clicked. Fantastic job
You can have different VLANS on different Switches as a way to split up the LAN and depending the route to the Router. However, depending on the LAN Topology with Switches, traffic can be permitted via configuration on another Switch for a VLAN. It depends on how the LAN is configured why you configure that. For inter VLAN traffic that VLAN Data Frame has to first travel to the Router which then repackage the Data Frame and then sends it back on the correct VLAN to the destination it was destined for.
I have a question guys, I'm a Newbie in the field of Networking. How could you add up to 4094 VLANs in a switch which probably has just 24 ports @ 4:18? Could you please clear that out to me? Thanks. Loveeee your videos by the way
Some interfaces can be configured to carry multiple VLANS. And some interfaces can also be configured as “Trunks” Ports connected switch to Switch where many VLANS are carried like an expressway over the Trunk Port. Just think of a multiple lane expressway carrying lots of traffic with each car lane permitted to carry a different VLAN with the Trunking feature. You can also have a large LAN with many switches in the LAN and on each the switch they have configured different VLANS that may be different to what’s on other switches. At times some those VLANS traffic need permit to travel in between different switches on specific switch ports. That don’t quite explain how exactly one uses up 4094 VLANS, but that’s the best I can do right now with my knowledge. I’m supposed to be taking my CCNA Cert Exam next week.
The difference between a Hub and a Switch is a switch unlike a hub does not broadcast to every node on a network..so why does the narrator says that the switch broadcast to every computer..please explain

"did you feel that?" "nope"
Brilliant.
I just discovered these videos, no other educational channels hits spot on like you, you have my eternal gratitude! ❤️
Thank you! Glad to have you here 🙏
Finally understood what Native VLANs. Thank you so very much.
JUST imagine the teachers wouldve teached like this guy...
Amazing Work ☝️

Now I understand VLANS better. Much appreciated.
Man, your explanation of networking concepts are so, soooo awesome. Thank you!!
I was so mad at school when I couldn’t understand this lol you helped a lot.
Really like your smooth explanation of native VLANs. It definitely drove the concept home for me - thank you!!
Oh I can make this problem a hell of a lot simpler for you. Just delete the entire HR department. That's 20 less ports for you to figure out.
🤭
You guys are awesome! I've learned more from your videos than the whole Cisco Netacad program I had to use through school.
Simple yet well explained.
I like your approach.
Thanks Dennis. Glad you liked it!
This is by far the best Video on VLANS or Networking Concepts that i have ever seen.
Trust me when i tell you that i have searched HIGH...
and i have searched LOW...
My friends this is worth your time, and definitely your support!
Thank you for putting this out there!

Thank you for the great comment! I had a lot of fun making this one! Glad you liked it.
this is the first time I understood native vlan, ty so much!
You are crushing it with these videos. So simple and clear. Well taught and you make everything just "click". Excellent job. Keep making vids like these and you're channel is going to explode > 1 million subs! Cheers
My friend recommended me this and i am not disappointed
Man the intro always gets me hyped

This video literally has all the answers to the questions I had. Great stuff.
Incredible - really struggled understanding tagged/untagged ports on VLAN's for ages until I found this vid, thanks! :)
- creating/separating broadcast domains; reduced broadcast congestions by using interfaces
fun little story to remember VLANs

Thank you Mike! Really appreciate the comment!
Thank you very much! This was a life-saver!
Great as always !
Thanks!
if it broadcast packets on all ports besides one that it received packet from then thats not switch but an hub
but switch will act as hub until it learn mac addresses
Great great content. Would love to see more videos on Cloud topics!
Great Video and i learn a lot. can i use your video to my presentation? if its okay? Thank you
Thanks Angelika! Great to hear the video helped. If your presentation is for personal use then go for it 😁
This is helping me so much! thank you
Excellent video and explanation

I’ve been looking at too much info and this is the first time this has been explained where it finally clicked. Fantastic job
Thank you for sharing!!
The video is loaded with tons of efforts to make it easy to comprehend!!!!!
Thanks for such an amazing video, but what does it mean when we have one vlan with one ip address or one vlan with multiple Ip addresses?
Thank you so much mate
Thank you. 👌👍🏵
So it is best practice to have all connected Switches in your environment set to the same native VLAN, I assume?
You can have different VLANS on different Switches as a way to split up the LAN and depending the route to the Router. However, depending on the LAN Topology with Switches, traffic can be permitted via configuration on another Switch for a VLAN. It depends on how the LAN is configured why you configure that. For inter VLAN traffic that VLAN Data Frame has to first travel to the Router which then repackage the Data Frame and then sends it back on the correct VLAN to the destination it was destined for.
Thank you for this video !!!!!!
No problem!
This is a great video ❤
Thank you !
You're welcome!
I am confused... By "hub" is the video referring to a "dumb switch" in the middle?
Thank you so much
Quality, thank you
The TCI is 16 bits long. The rest of the video is really usefull.
I meant it contains 3 separate bits of information, not 3 bits in length. I can see the confusion 🤣 Glad you liked the video.
Great video, thanks!
Thanks Jose. Glad you liked it!

Is it @davidbombal narrating all clips?
I'd be lucky to have Davids accent 😂
Can we assign up address to a VLAN
Awesome 👏 like ever 💙
Thanks Haron!
Great content
Thank you 👍
Thank you!
Thank you
love it
I need DNS explanation TT, thank you
It's on my to-do list 💯
How does a router split the LAN's?
how can i get your full ccna course portal
Hi Neil, if you register your interest in the description you will be sent the pre-launch link.
Subscribed.
what if there is a router in the network?
The difference between a Hub and a Switch is a switch unlike a hub does not broadcast to every node on a network..so why does the narrator says that the switch broadcast to every computer..please explain
It does it when their is an ARP Request. It does a broadcast to every active port except the one the data frame request came from.
