What is VLAN and Why VLAN?
HTML-код
- Опубликовано: 30 июн 2024
- Today my topic is VLAN, and why we need VLAN.
VLAN stands for Virtual Local Area Network. VLAN is a logical network that can group devices /users regardless of their different physical locations. A VLAN is created at the switch.
Why VLAN? There are many reasons why we need VLANs. In this video, I will talk about 3 reasons: 1) Segmentation 2) simplicity of network design and deployment 3) simpler troubleshooting and management.

hello Sir Sunny, I like your detailed Vlan Video. Hope we can see an actual Laboratory vlan setup soon. :) thanks.
thank youu sunny..inspired mee..
Thanks Mr Sunny... very simple and clear

I like the simple way complicated VLAN's are explained
Thank you !
You are a pretty awesome dude! Thank you!
love u sunnny great job
Sunny, you are the best.😅
You are the best too. Many thanks for your compliment.

Perfect
Thanks a lot.
You are quite welcome, Rami.
Thank you 😊😍💕💕🌷
Hi Sunny , Can you make a video about VoIP ? Thanks for your other video's it helps me a lott !
Plz make a video on Subnets Vs VLANs.. Thanks
I don't have much words to describe how best talented you are. you are naturally gifted person to teach. Keep up you good work.
Thank you for your compliments!
thank you so much for this informative video :)!! but what doe sit mean when we have a vlan with one IP address or one vlan with mutiple IP addresses?
Thank you
Don't mind me just making myself some notes:
- separating broadcast domains - independent networks by grouping devices regardless of physical location
- created at the switch
Segmentation
- connection to one switch means devices belong to one broadcast domain - where broadcast from one machine reaches all in that network.
- Too many machines in one broadcast domain can cause congestion and thus performance issues and may have to be separated
- Computers from different departments thereby different functions may have to be separated for security reasons
- Instead of getting multiple switches for each network/broadcast domain and routers to connect them - hardware cost - one single switch can be used
Thanks
thank you
thank u sir
Hey Sunny! Does VLANs separate broadcast domains or networks? I'm confused here.. If we have 2 VLANs on one switch will the devices on the two VLANs be able to talk to each other if they just are talking normally (one to one). And will the VLAN only separate broadcast traffic?
ruclips.net/video/59LIOPaaQVA/видео.html
Good Morning,
great video but I have any question:
why for each vlan must correspond a different subnet? why I can't use the same network for divide in VLAN?
If I just use different subnet, why I need to separate logical LAN in VLAN? the broadcast traffic is just separated with subnet and also segmentation.
why is it not a redundant solution? is true that VLAN work at level 2 and subnet at level 3 but if I use subnet I reach the same goal. or not? please clarify my ideas with simply example.
Thank you so much
you are number one.
First, let's keep it simple. A subnet is a LAN, physical or virtual. VLAN is just like a physical network. VLAN is a LAN, layer 3 because almost all networks today use TCP/IP. The reason why we say VLAN is layer 2 because we can use layer-2 switch to create VLAN, but it doesn't mean it is a layer 2 network. Keep in mind, on a local area network (including vlan), all communications are local, but communications with other networks beyond are remote, which needs IP addresses.
@@sunnyclassroom24 Ok, so in pratically if I configure this:
Host1: 192.168.80.1/24 Host2: 192.168.80.2/24 in VLAN10
Host4: 192.168.80.3/24 Host5: 192.168.80.4/24 in VLAN20
Connected at the same switch L2
what is the difference in having Host4 and Host5 in another network (192.168.83.1/24 and 192.168.83.2/24 in VLAN20)?
why the goal is not the same? (however with 2 different VLAN the LAN is divided)
When you segment using vlans do you still need to subnet the network for 2 vlans to communicate? How would the IP addressing work?
Hi sir.. Give any information about the books related to it.
Which books would be good about this?
Hello Sunny.. Could you share me some information about why exists VLAN 1 and how it was created?. . I know in this vlan travels all kind of information data/video/voice, . That's the reason?. And The last question if 1 or more VLANs are Created into the switch why the rest of vlan are tagged and the vlan 1 not.. , I mean from vlan with number 2 to 4096
on the switch are tagged and the information on the
Vlan 1 is untagged if all of them are VLANs..
Hey Sunny, It is easy to talk about it but what about showing CLI commands to prove your point.
First, let me introduce the basic ideas. Then I will upload more advanced videos. Right now there are a lot of other youtube videos showing how to use CLI commands. I hope you could find some.
Thank you Sunny. I look forward to your CLI videos.
@@tahersadeghi6773 Thanks a lot for your patience and you are welcome!
i thought a switch can only send data to its intended port? i thought the hub broadcasts the data for all devices on the network to see.
I see some of the playlists in the channel are not numbered, please fix them. Thank you for the videos.
👍
two vlans created 1 for HR and 1 for Sales Dept. if i created a shared folder and connect a network printer from HR Vlan those vlan under sales department cannot able to see it right?basically i want to hide the network printer, shared folder or NAS from other departments via Vlan. is this applicable or good solution? thanks.
Keep it up
Thank you for watching!
I am trying to implement a dynamic VLAN connection on windows 10 using IPs using only one hardware connection between my computer and the RAD-Moon I am using .. I know it's doable on windows server and Linux and there is some commercial apps on windows too .. can u help me ?
Thank you for the quality of your course, could please send me a power point of your course.
Can you have vlans connected by two or more routers
No one explain simpler than this,
Thank you for watching! I appreciate it!
Which tool did you use for the animation ?
I use flash.
VLANs do not group users, they group ports. VLANs can be based on other parameters beyond ports, like MAC addresses, but that is not common. VLANs are groups of ports.
All traffic entering a port is considered part of, or on, the VLAN the port is assigned to.
Sir whats the difference between vpn and vlan
Thanks for your videos.
Please and thanks for your help. I am upgrading my church network and need your help. Current network was setup by someone else who is no longer available. We have 1 domain controller for the treasury dept. which is separated from the rest of the network with its own static ip address. 3 other static ip address for 3 other groups. Each group is on it's own router. I got rid of the static IP Addresses and replacing all network equipment with unifi. Including udm pro, 2 8 port switch and 16 port 2nd gen switch, 3 AP's for now. I will have about 4 vlans (possibly more). I want to maintain the DC with a static ip 192.168.31.3. and have it issue ip addresses to the treasury computers. I want to setup vlans on the udm pro and have it issue ip addresses. Reseach show that I should use dhcp relay on the udm pro for all equipment talk to each other. I would like to be able to share files and printer with some of the vlans. Please advise if how would I go about setting this up. What do I need to do on the DC running windows server 2012 and what do I need to do on the udm pro?
VLAN was originally created to mitigate broadcast storms
what is the difference between VLAN and VPN ?
I will do one video about VPN. Thanks a lot for your patience.
Why don't you have a icnd 1&2 course? 😭
My videos cover many aspects of ICND basic networking. However, Cisco related exams would be covered ultimately. Thank you very much for your patience.
You are saying some inaccurate points in this video.
VLANs do not ‘talk to each other’. Traffic can be forwarded from a source on one VLAN to a device on a different VLAN.
Hosts or end stations talk to each other, VLANS do not talk to each other.
