Default VLAN and Native VLAN
ฝัง
- เผยแพร่เมื่อ 12 มิ.ย. 2024
- default VLAN:
We cannot change the default VLAN. We cannot even delete the default VLAN. It is the default setting. It is VLAN 1.
The default VLAN is only relevant to an access port
VLAN 1 is never intended to be used as a standard VLAN to carry network data.
Native VLAN:
The Native VLAN is simply the one VLAN which traverses a Trunk port without a VLAN tag.
The default Native VLAN is VLAN 1, but it is recommended to configure the native VLAN to different numbers other than 1.
Native VLAN is configurable on the Trunk point, not on any access port.
The native VLAN should be the same on both ends of the trunk. If both sides of the trunk do not agree on the Native VLAN, the trunk will not operate properly.

I've learned more from Sunny about VLANs than anywhere else.
I really appreciate your teachings. You explain complex topics so simply for everyone to understand. Thank you Sunny
So basically Native VLAN traffic does not need a tag to travel, that makes it so useful. Thank you for sharing your knowledge.
Enjoy watching your videos which explain things clearly within 10 minutes. Like the way you speak - not too fast, word by word, very clear. Also, like your closed captions. Please keep up the great work!
Great lesson Sunny. As others have said all of your lessons are well thought out, clear, concise with really well communicated explanations on the basics and more advanced topics. Thank you
Sunny your explanation is always super easy to understand... Thanks for sharing such wonderful knowledge with the entire community.
My pleasure 😊
I just came across this channel and this gentleman explains these topics so very clearly. I am really hooked here. Good job sir.
The best explanation i've seen. Not only what it is, but also how it came about and what it is used for.
Sunny! Your explanations are detailed, simply, and easy to understand!
Many thanks!
Short.Precise. To the point. Well explained 👍🏻
Awesome work mate. I really appreciate your take on the topic and the visualizations illustrate everything perfectly. Thank you!
Exactly the information I was looking for because we have computers connected to VoIP phones but we want to keep VoIP traffic separated on its own VLAN. Thank you.
BEST IT INSTRUCTOR I HAVE EVER WATCH!!!! THANKS FOR SHARING!!!!!!!!!!!
You are a very talented instructor. Thank you Professor :)
You are very welcome
You are the best. Your Sunny table made my practical exam a piece of cake!
Thank you again, Sir!
Great explanation, Sunny! Thank you so much.
Thanks Sunny, your education is very useful, your explanation is clear and can be easily understood.
Really appreciate you teachings, very simple and effective.💪
Sunny, thanks for your post. It has all the details that I need to grasp the concept of Native VLAN. Keep it up Sunny.
another very clear understanding video! Thanks Sunny
You re welcome !
Great to have found your Videos , Sunny. So well explained by you
Your explanation is extremely high helpful and gives pretty much knowledge. Thank you very much, sir!!
You are welcome!
Great and clear content that helps learning process, congratulations!.
Thanks.
It's nice simple explanation. Love and respect from Anand Bharat.
Thank you so much. I've finished the Cisco networking academy classes but never fully understood the purpose of a native vlan and why it even exists.
You are welcome!
i am suffering from cisco networking academy class now, sunny is sooooo helpful
Hi Mr. Sunny, you explained very sweetly and clearly , i enjoyed the content. keep it up
This video is I am looking from ages.... Awesome work
Thanks sunny, this is the explanation that everyone needs!
So informative video! Thanks a lot Sunny!
Very clear explanation thanks Sunny
Thank you so much Sunny!! Awesome work best teacher
You are such a great instructor
Thanks for a clear explanation on Native Vlan. I have a suggestion: the telephone exemple is a great way to explain the native vlan usefulness. I suggest you add another pair of PC/computer to shwo that you can assign a different vlan on each trunk port. Thank you. It took me a while to be familiar with the concept. you helped me a lot.
When the right person explain the big confusing thing at many people should be easy thing at the end
I have no idea about vlan further more native vlan but now I have. thank you very much
This was very helpful. Thank you!
It was really usefull for me, explication was so clear, thank you Sunny,
Great explanation as usual making things simple.
now it cleared so much for me about native vlan .thanks .
Sunny i appreciate your teaching ways and more so the way u explain these things may Allah increase u in knowledge
I wish I got the chance of attending your physical class. But all the same thank u so much!
Thanks Sunny, great explanation!
You are welcome, and thank you, George.
"The native VLAN is a per trunk, per switch configuration" - this helps. Thanks!
you are welcome!

Sir,
Can we get the link for these tutorial slides please? Thank you in advance
Omg this is so helpful! Thank you 😭
Thanks for explanation. I like it very much..
Simply great tutorials....
"the angel" number , I had to think twice about that , you stand correct
Thanks you for sharing the knowledge.
You are welcome!
I have been searching on the Internet for what is Native VLAn and it's purpose also What traffic is going through the native vlan from days. Finally..I got my answers in this video.
Thanks a ton.
good scenario, thanks Sunny
very good explanation..great sir.❤️❤️👌👌
Ur videos always helpful and useful..
thanks a lot!
You have a great channel 😊
Outstanding! I really appreacte your efforts, time and explanation which are great and easy to understand but i would like to request you that if you write/put the steps (how to create vlans, switch port, trunk, voice vlan and data vlan and etc, below the description of this videos and other videos and if you have free time then make it would be more than great, so i am waiting for your response as soon as you can. Thanks alot
Great job, for a first timer like me, i did understand, thank you Sunny, rock on!
You are welcome!
Simply awesome video!!!
Great as always!
Thanks for the video!
great and very useful and on target , keep rocking
Thank you, I will.
Thank you for this!
i am getting ready to take my CCNA exam, and literally still didn't get the difference in between native and default vlan, especially when native in default is VLAN1. So this video definitely helped.
Good luck with your CCNA exam.
Thanks Sunny!
Thanks! that's very informative
sunny rules. not only are the vids great but the little jingle at the end is pretty awesome too...
Thank you very much
Very helpful. Thanks!
FANTASTIC !!! THANK YOU !!
You are welcome! Thank you for your support!
Sunny, did it again! 🙂
You should write a book with illustrations, Sunny. I would buy it for sure
Thanks a lot!
Me too 👍🏻
Excellent ... Well done ...
Thank you!
awesome video sunny, you are genius.
Thank you for watching! Check out my other videos please!
Hello Sunny
You explain verry well.
I Never see this.
You sould be teacher
Thanks
Thanks
very good content, thank you
One word “BEST “
Thanks a lot, RASHIK.
Great job
Very good video
Native Vlan was very explained.
Damn bro, this is gold!
Hi Sunny in your last example of the VOIP application, what will happen if VLAN 30 (data vlan) is used rather VLAN 10 (native vlan)? Can PC A still communicate to PC B?
Good Job Man nice explanation
Glad you liked it
Best example !!!
Thanks
Another useful tutorial...
Thanks a lot.
@@sunnyclassroom24 You are welcome.
Really appreciate it. Thanks Sunny
Hi Sunny,
Greetings!
what will happen technically if the native vlan mismatches between the two trunk links?I mean does the tunk links behave something different ?because though the native vlan mismatches, the tagged vlan frames will pass through the trunk ports then what is the issue with the native vlan mismatch.Could you please take a look on this and clarify the doubt.
Muito bom!
@Sunny Classroom, can I ask you about best practises for more than two native VLANS? I need to do upgrade my distribute switches from L2 to L3. To do this I will need to create new networks admin subnets for all access and distribute switches. During above procedure we will have transition period (several months) where I will need to have (on my core switch L3) several VLANS configured as a native on uplinks to distribute switches. What about such setup and what should I remember or pay attention on?
Im using a cisco switch 2960 and when I configure the native vlan I can see it with the show int trunk command, but I never created that vlan so I do not see it in the show vlan brief, why? does switchport trunk native vlan not create the vlan? or it is not required to create it manually?
Hi Sunny,
here we have pcA with vlan10 without configuring it to switch. So is that bcoz we have pc A connected to phone1 and it has build in switches?
Also what if we are not predefining native vlan here and is it necessary to define native vlan in trunk port ?
Hello Sunny
Do have to include or allowed vlan natif on trunk link
for example :
vlan native 100
vlan 10 and vlan 20
switchport trunk encap..
switchport trunk allowed vlan 10,20
switch mode trunk
i have to allowed vlan 100 (switch trunk allowed vlan 100,10,20) or not and why.
Question, from the last example about using the naive VLAN, what would happen if Computer that connects to up phone also has VLAN tag?
Great question! We might need a router to direct the traffic so that the data traffic is delivered through the phone. In that situation, the phone functions as a switch for the computer. There might be some configurations.
@@sunnyclassroom24 Realizing this is two years old, but why would a computer have a VLAN tag? Computers send and receive untagged frames, the tags are assigned and removed at either end of the trunk, correct?
Sunny, can you give us your opinion on where the industry is heading and if Network Engineers will be obsolete
hey can 1 vlan switch can connect in 5 unmanaged switches ? or vice versa
i don't understand one thing. if i have two switches connected, i set the native vlan 10 as native vlan, if the traffic flows without tagging on the trunk i have no problem to let pc A and pc B to comunicate, but if pc A has to comunicate with a pc C on an access port with pvid 10 on the switch i need an hybrid port, so i can say if something untagged comes to the port set the tag 10, so pc A and pc C (the one on the access port ) can comunicate. i dont find very usefull this scenario.
Would like to ask, for the VoIP part, the PC Vlan 10 will be tagged by the IP Phone then forward to switch, am I understand correctly?
Like to check if you are giving VLAN 10 as Data and Native VLAN in your VOIP example ?
in case we use 802.1q the data between two switches will be tagged or untagged please ?
Sir, plz make a video on differences between subnet and vlan
Love your accent. Very helpful lecture
Thanks.....
You are welcome!
