Default VLAN and Native VLAN
Vložit
- čas přidán 31. 05. 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.
Sunny! Your explanations are detailed, simply, and easy to understand!
Many thanks!
The best explanation i've seen. Not only what it is, but also how it came about and what it is used for.
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
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.
I just came across this channel and this gentleman explains these topics so very clearly. I am really hooked here. Good job sir.
Awesome work mate. I really appreciate your take on the topic and the visualizations illustrate everything perfectly. Thank you!
Thanks sunny, this is the explanation that everyone needs!
Sunny your explanation is always super easy to understand... Thanks for sharing such wonderful knowledge with the entire community.
My pleasure 😊
Short.Precise. To the point. Well explained 👍🏻
Really appreciate you teachings, very simple and effective.💪
You are the best. Your Sunny table made my practical exam a piece of cake!
Thank you again, Sir!
Sunny, thanks for your post. It has all the details that I need to grasp the concept of Native VLAN. Keep it up Sunny.
BEST IT INSTRUCTOR I HAVE EVER WATCH!!!! THANKS FOR SHARING!!!!!!!!!!!
Great explanation, Sunny! Thank you so much.
You should write a book with illustrations, Sunny. I would buy it for sure
Thanks a lot!
Me too 👍🏻
Thanks Sunny, your education is very useful, your explanation is clear and can be easily understood.
You are a very talented instructor. Thank you Professor :)
You are very welcome
It's nice simple explanation. Love and respect from Anand Bharat.
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.
Great to have found your Videos , Sunny. So well explained by you
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
Your explanation is extremely high helpful and gives pretty much knowledge. Thank you very much, sir!!
You are welcome!
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?
another very clear understanding video! Thanks Sunny
You re welcome !
This video is I am looking from ages.... Awesome work
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
So informative video! Thanks a lot Sunny!
You are such a great instructor
Thank you so much Sunny!! Awesome work best teacher
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.
Very clear explanation thanks Sunny
Sunny i appreciate your teaching ways and more so the way u explain these things may Allah increase u in knowledge
Great explanation as usual making things simple.
Great and clear content that helps learning process, congratulations!.
Thanks.
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.
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!
Thanks for explanation. I like it very much..
It was really usefull for me, explication was so clear, thank you Sunny,
I wish I got the chance of attending your physical class. But all the same thank u so much!
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.
now it cleared so much for me about native vlan .thanks .
Simply great tutorials....
Thanks Sunny, great explanation!
You are welcome, and thank you, George.
Simply awesome video!!!
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?
Great as always!
@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?
good scenario, thanks Sunny
very good explanation..great sir.❤️❤️👌👌
"the angel" number , I had to think twice about that , you stand correct
Omg this is so helpful! Thank you 😭
Thanks you for sharing the knowledge.
You are welcome!
Thanks for the video!
Ur videos always helpful and useful..
thanks a lot!
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 ?
Thanks Sunny!
Thank you for this!
You have a great channel 😊
Thank you very much
sunny rules. not only are the vids great but the little jingle at the end is pretty awesome too...
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?
Thanks! that's very informative
Excellent ... Well done ...
FANTASTIC !!! THANK YOU !!
You are welcome! Thank you for your support!
Very helpful. Thanks!
"The native VLAN is a per trunk, per switch configuration" - this helps. Thanks!

Sir,
Can we get the link for these tutorial slides please? Thank you in advance
Thank you!
great and very useful and on target , keep rocking
Thank you, I will.
hey can 1 vlan switch can connect in 5 unmanaged switches ? or vice versa
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.
Great job, for a first timer like me, i did understand, thank you Sunny, rock on!
You are welcome!
So in order for a trunk port to work, it has to have one untagged/native VLAN, correct? If so, when we create a native VLAN, do we have to enable DHCP on it?
You do not assign IP on a native vlan for security reasons. You could add IP on a seperate vlan(management) just so to have access on the switch for remote configuration via telnet/ssh. And yes for trunk ports there should be the native vlan assigned to them.
Hello Sunny
You explain verry well.
I Never see this.
You sould be teacher
Thanks
Thanks
awesome video sunny, you are genius.
Thank you for watching! Check out my other videos please!
Great job
very good content, thank you
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?
in case we use 802.1q the data between two switches will be tagged or untagged please ?
if two sides of trunk port have an "acsess mode", does it work? (or they only work with "trunk ")
trunk ports are two ends of a trunk. The access mode is for an access port.
Sunny, did it again! 🙂
One word “BEST “
Thanks a lot, RASHIK.
Best example !!!
Damn bro, this is gold!
Thanks
Sunny, can you give us your opinion on where the industry is heading and if Network Engineers will be obsolete
Very good video
Hello Sunny, I am using None Cisco equipment, however my question is, what is the best practice to configure Access-Point to the switch (SW-AP)? Its better configure as trunk? Or access port? What i am trying to accomplish is, i want to add APS, Switches to managed VLAN, and mapped SSID to different VLAN. By the way i am using ubiquity requirements.
from a device (computer/server) to a switch, no configuration is needed for an access port. From a switch to another switch, trunk ports are needed to create a trunk.
Thank you sunny. How about switch to access point?
@@KavanMavati two or more switches are connected and communicate with each other (different broadcast domains) either through a traditional router or interRouting through trunking. Unless we use the traditional approach (see my video "what is VLAN and why VLAN" ) where a router physical interfaces are connected to each switch (access port), trunk ports are needed.
@@sunnyclassroom24 my topology is router on the stick, I have several inter vlans, router act as dhcp. I understand switch to switch, router to switch it have to trunk mode. Traditionally yes I know u can set access point to untagged port.
@@KavanMavatiyou are correct. RoaS would need trunk, I assume.
Does anyone now how to make these clips that show the red dot (traffic) moving down the line? Im wanting to make some animated presentations for work but now sure how.
6:45 even if we don't mention native vlan 10 on sw1 and sw2 trunk port, still pc A can contact pc B right ?
Great question! We must configure VLAN 10 as native VLAN on the trunk ports because by default native VLAN is VLAN 1. Thanks a lot for your question.
@@sunnyclassroom24 is it stiil working because of DTP?
"The native VLAN is a per trunk, per switch configuration"
Where do native vlan frames go once they reach S2?
Good Job Man nice explanation
Glad you liked it
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.
Another useful tutorial...
Thanks a lot.
@@sunnyclassroom24 You are welcome.
Really appreciate it. Thanks Sunny
