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.

[@Certbros]

Thank you Khider! 🙏 Making this video was a lot of fun so I'm glad to hear it helped you get an understanding of VLANs!

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!!

[@Certbros]

Thank you for the great comment! I had a lot of fun making this one! Glad you liked it.

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

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!

[@lysaali50]

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

[@austinbrinkman1992]

You guys are awesome! I've learned more from your videos than the whole Cisco Netacad program I had to use through school.

[@tebs1989]

Man, your explanation of networking concepts are so, soooo awesome. Thank you!!

[@ardentdfender4116]

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.

Now I understand VLANS better. Much appreciated.

[@vesder819]

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.

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

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?

[@orkovas1827]

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)

[@hanisirfan]

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.

[@heptagondev]

Your videos fun to watch. Thanks for your great videos. You deserve more subs

[@abelashenafi6291]

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

[@ardentdfender4116]

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.

[@elionaidgranados1005]

the way you explained couldnt be more crystal clear

[@sleekspeed22]

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.

[@heroclix0rz]

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.

[@abcpsc]

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?

[@ardentdfender4116]

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.

[@nullsemicolon]

Your videos are great!

[@Certbros]

Glad you like them!

[@gasergaser8629]

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

[@abhikumar-vu4my]

Thanks Angelika! Great to hear the video helped. If your presentation is for personal use then go for it 😁

[@dina3314]

thank you so much for such a video

[@George-nq2mx]

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?

[@MaxUgly]

I am confused... By "hub" is the video referring to a "dumb switch" in the middle?

[@SuperAlashi]

Awesome 👏 like ever 💙

[@JoseGarcia-uz8uc]

[@Certbros]

Thanks Jose. Glad you liked it!

[@hecta14]

How does the switch know there has been a native vlan mismatch if the frame is untagged? Is it because the frame has not been forwarded on the second switch? If so, would the message pop up if there was a pc with vlan 20 connected to the same switch?

[@Certbros]

Great question! The switches use another protocol for this. For example CDP will tell the neighbour switch its native vlan.

[@hecta14]

@@Certbros Thanks, cheers!

[@Rhand007]

So it is best practice to have all connected Switches in your environment set to the same native VLAN, I assume?

[@ardentdfender4116]

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.

[@Certbros]

[@gregores5107]

How does a router split the LAN's?

[@priyanshubangarwa4316]

Can we assign up address to a VLAN

[@antoniodaley836]

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

[@ardentdfender4116]

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.

[@yomeroelalex]

The TCI is 16 bits long. The rest of the video is really usefull.

[@Certbros]

I meant it contains 3 separate bits of information, not 3 bits in length. I can see the confusion 🤣 Glad you liked the video.
