I am halfway through and stopped to say I already learnt more than what I've learned in 2 years in uni about VLANS plus trunk and access, thank you, sir.
One of the best explanations I've seen on youtube. Thanks! You're the only one who really goes through the Why/How/When rather than other people only explaining the What.
You're very welcome, Chris. Glad it makes sense. Could you do me a favor? Do you mind sharing this video on Linked In, Reddit, Twitter, Facebook, or any other social media you use? As an independent creator, that would be an _enormous_ help, and I would appreciate it _greatly_ .
Kinda knew what VLANs were for years but just watching this video it's all clicked first time. I have pretty bad ADHD but your style of teaching worked perfectly!
I don't usually comment but i have to say, this is probably the best video out there about vlans. No weird analogies. no talking too much, and no useless stories... I also love how you made Native Vlans a piece of cake, literally it only took you about 2 min to make something so clear. However, i do have one question. If the native vlan was set to 50 (in your case), where would the traffic go, just get dropped? You are literally the best! THanks man!
Amazing explanation on complex topic of VLAN for network newbies. I read the articles and watched the video, consolidated multiple switches into one switch at home and simplified the network.
I've watched several videos on VLANs and this is the most concise and helpful video that I've found. Thank for explaining the purposes of VLANs as well as Trunk and Access Ports. The way you transitioned between sections was also very intuitive and helpful.
Excellent presentation!!! I already “knew” everything covered in this video, yet by the end it was like I was really understanding it for the first time. Well done. 👍
Oh my god... this video is so good wth!!! It is so clearly explained and easy to understand. I'm in a new IT role and I recently had a request to patch two ports and have those two ports added to two different VLANs on our switch. I thought to myself... "Why can't we just allow one port to access multiple VLANs?" Our Network Engineers basically said that was a big nono and this video helped me understand why that is!
=) Thanks for the kind words! I'm glad you were able to understand your Network ENgineer as a result of this video. You might like my Networking Fundamentals videos as well: www.practicalnetworking.net/index/networking-fundamentals-how-data-moves-through-the-internet/
This video made me feel so much better about delving deeper into IT. Literally I started smiling at the halfway point out of excitement... thank you. Subscribed and Bell
This explanation is so simple and yet so concise and to the point. I also love the way you make a review after major section to reinforce the learning. I'm not new to networking and have been in the industry for a while now but I can't help to admire the way you know how to dissect a complex topic into easy digestible chunks. Absolutely awesome!
@@PracticalNetworking At 10.11 “When a trunk port is sending a frame - does not belong to the native VLAN - the frame is sent with a tag” Does it strip the vlan id 30 and add vlan 10 ? Or it keeps 30? What does it mean when you say the frame is sent with a tag ? Please explain!
This video is a fantastic presentation of the Vlan concept. I love the crystal clear, concise explanations along with the great animations. Indeed, a work of art.
Just loggged in to post this: this is by far the best explanation of VLAN I found. It is clear, consice, and the animation is perfectly right on point! Great work, and thank you!
your videos are absolutely amazing! i'm in an intro to networking class and was so confused. i watched this and suddenly had that moment of "oh my god! i get it! i know what's going on!" thank you so much!
Beautifully done explanation going through all of the important questions quickly without being confusing. The one question I had that you did not specifically address in the video (mismatched Native or Access ports between switches) was thoroughly explained in the article. Answering the two challenge questions on the article further clarified things for me. First time in my near 20 years in IT I actually think I understand VLANs.
Inter vlan trunking is possibly my favorite topic in CCNA. That and fhrp and link aggregation . Thank you for all of this. You do an amazing job of illustrating things I didn't know, that my professor assumed I did know.
OMG! THANK YOU, THANK YOU, THANK YOU!!!! I have spent the last 8 hours trying to understand the concept (reading and re-reading the Cisco book) and I swear I thought I was stupid for not getting it. 🤦♀️ Thank you so much, I finally get it!!! 🤗🥳 you are amazing, in case I wasn't clear THANK YOU!!! ✨
The presentation is so good, SO GOOD - it is concise - best 12 mins covers - VLAN, Access/Trunk, Frame, 802.1q, Native VLAN - I have to bookmark this one. :) Thank you !!!
Very good videos. No fluff, well prepared and presented, and technically correct. And your use of Wireshark to show the packets with and without the tags makes the concept more tangible. The magic of 802.1Q (compared to ISL) is the use of the ethertype 0x8100 to let a vlan-aware device know that this is a tagged frame, while still allowing most non-vlan-aware switches to still forward vlan tagged frames, although doing so isn't best practice. Thank you for taking the time to make these videos, they are very helpful.
This has been incredibly helpful to me in understanding these concepts and what their implications actually are. Thank you for such a concise and clear, step-by-step explanation
Really great video! I do have an question: 10:00 - if we have a Native VLAN mismatch between switches. If we have Switch-A with Native VLAN 10 and Switch-B with Native VLAN 20. Both trunk ports support VLAN 10 & 20 Our PC is sending data with VLAN 10 from Switch-A to Switch-B. Since Native VLAN for Swich-A is 10, would Switch-A send untagged frame to the Switch-B, which would add the tag of VLAN 20 or would Switch-A send tagged VLAN 10 frame instead, because of Native VLAN mismatch? Thanks!

glad you are backto having some vids. the packet tracing vid was great. i read the articles of this vlan stuff a while ago. good brushup. my suggestion would be to make a vid on those challenge questions. i got most of them wrong lol
Great video! when you get a chance please make a video explaining how to configure a netgear type of VLAN in which you use PVID, untagged, tagged, no untagged and stuff..
The bottom one is physical as it represents how everything is actually connected to the two physical switches in the topology. But with the three VLANs it operates as if it were three logical switches (represented in the top photo, the logical diagram).
good explanation of how and when tagging happens and Native VLAN (PVID). Could have taken it one step further to show how the 2 routers can be one physical router but I guess that's the next layer.
Thanks Dominic. Agreed. I wanted to keep this video just focused on VLANs / Switches. I do discuss Routers and VLANs in this article: www.practicalnetworking.net/stand-alone/routing-between-vlans/
Glad you enjoyed this video. =) Yes, VXLAN would be fun to cover. But alas at this time I have no imminent plans -- to many other topics are on my list to cover next.
I was just diving into container networking. Your explanation of VLAN clicked soo good to me that I kind of understand the motivation behind network virtualization. Your explanation is always crisp and to the point. These excellent visualizations are like icing on the cake. For someone like me without any formal networking background, your work is so easy to digest :) Any chance you would consider virtual networking as a topic in future :) ? I would happily buy that course. Grokking container/kubernetes networking without proper virtual networking (or networking foundations) in general is next to impossible
If the port on the right is set to access mode VLAN 30, how does traffic from the left ever reach it? Isn’t it only supposed to allow traffic tagged VLAN 30?
When an access port receives a frame it associates with vlan tag configured , but when access port sends a frame , will it tag to that vlan or send only untagged packets. Another query is that when one end of interface is configured to vlan 10 and the other end to vlan 20 and both are access ports , will the traffic flow?
Yes! The traffic will flow, but you'll end up in traffic in an unexpected VLAN. To see this in action, check out the challenge question in my VLAN article: www.practicalnetworking.net/stand-alone/vlans/#challenge
I just wonder is there a crosstalk between two switch? because you connected to two connection wire from switch to another switch. Or it just data not a physical wire?
Not sure I follow your question... Perhaps they are answered in these videos on Switching though? ruclips.net/video/AhOU2eOpmX0/видео.html ruclips.net/video/G7GyWjJtjNs/видео.html
your videos are the bomb. I learn so much from them. Could you combine this presentation with the "how packets travel througn a network" to see what happens throughout the whole process with tagging and such?
If your comment gets enough likes, I will consider adding a switch with trunks to a packet traveling type illustration. Glad you've enjoyed the content otherwise =)
Great video. I hope you discuss how Routers exchange routing information like OSPF(Link State Protocol) & RIPv.2(Distance Vector Protocol)& EIGRP(DV & LS Protocol). Thank you.
Thanks for the suggestion =). I've written three articles on EIGRP, those might help in the mean time. www.practicalnetworking.net/stand-alone/eigrp-terminology/ www.practicalnetworking.net/stand-alone/eigrp-metric/ www.practicalnetworking.net/stand-alone/eigrp-feasibility-condition/
What if the MAC address is not known, will the switch forward a tagged packet to every ingress port or will it look at the tag/VLAN ID and forward only to ports that belong to that VLAN?
Glad you enjoyed it! Thank you for the feedback about the audio. I just recently changed the way I do my audio engineering and that might be the culprit. It will be better in the next video!
Does a trunk port need to be capable of higher bandwidth than the access ports to avoid potentially becoming a bottleneck? If I understand correctly, they’ll be processing much more traffic than an access port.
Yes! That's great reasoning. That is why switches typically come in with ports of multiple speeds. i.e., you might see a Gigabit switch with 24 or 48 Gigabit ports, but then two Uplink ports that are 10G speed. The idea is for those to serve as the Trunk ports and have more capacity to aggregate all the 1000mbps ports.
I think that means its sinking in ;) At the very least it will help you remember everything if you get a slight chuckle when thinking about VLANs in the future.
