I have been studying for the CCNA for about a year. I have the official text books which I have read several times. I have also spent countless hours going through two video courses (one paid and one free). No matter how much effort I have put into my studies, I just never felt like was getting it. UNTIL I found Jeremy's videos!!!!!! Amazingly clear and thorough explanation of all topics and very useful quizzes to help ensure the main points are understood. I can't recommend these videos enough. I don't think this information is presented in a more thoughtful manner anywhere. Thank you so much for this amazing resource.
Day 17 is a milestone .....it's like CCNA is saying know your level I am a difficult course but @Jeremy'sITLab made everything simple and all you have to do is to go over the VLANs videos over and over until you find your feet ........Thank you for this amazing work MR Jeremy
I worked for an ISP for a while but didn't get into the networking side of stuff mostly just installs and a little bit of replacing/adding new equipment. But everything was GUI. I recently went to a different ISP who uses mostly CLI. They use Juniper and so I started doing the Juniper training and learning CLI... as soon as i got to routing and vlans I was lost they don't explain it very well at all. So i came here and have been doing the labs (albeit over and over again to drill commands into my memory). Jeremy gives a good overall explanation and after going "huh" over at juniper, i did these last few videos and went back to the "huh" vid at juniper and went "oooh ok i get it... why couldn't you just say what jeremy said?" These vids while yes they are for ccna, they're helping with my jncia 10x better than the jncia course. THANK YOU JEREMY'S IT LAB!

I have been searching for the Courses offered for CCNA because for the content but you totally break the myth. On my experience it's is only one the best content videos with free of cost. Great inspiration 👏👏 bro
this one was kind of tough, i took a lot of notes tho. but i think im gonna watch it over to get a better grasp on it. i am however much more knowledgeable in VLANS and know how to configure them. never knew any of that until i watched this video and the previous. thanks for all the info, Jeremy!
These videos are a great resource to accompany my other resources when training to be CCNA certified. They'll accumulate a lot of views over the next couple of years.
Well that was a heavy video I had to watch it two times but after all I was proud of myself when I was able to answer the quiz questions! Thank you!! :-)
Thanks very much Jeremy for the update. Though am going through the same course from another instructor but am always eagerly waiting for your update cos its the best so far. Can`t wait for the next update.
Jeremy, I did my CCNA more than 20 years ago, and I am able to follow along although with a much older brain! I'm really enjoying your presentations and agrre with lots of other comments, you have a very easy way of explaining things! I did pickup a mistake though! Relax, not in any of the content - your heading at 32:46 reads 'Things we have coverered' :) well done on your channel!
I want a job as datacenter technicam here sweden and this course is all a need! Incredible free course! Now o know more than many datacentertechnicans😁
This one definitely was tough. Every other day I've breezed through with little to no problems. But as tough as it is I like it to, thanks for the awesome content and explaining this so well!
Quiz Question 4. c) TCI voice, but PCP on screen. A minuscule problem that I found in your entire set of videos. Congrats and many thanks for you work, Jeremy!
Thank you so much for your time and effort on all of these videos Jeremy, I've been struggling to understand a lot through the traditional IME course I was using before, now I understand everything clearly! Quick question - if we were to try and get the CCNA exam done before the end of the year, what would you suggest we learn from here if we were to use another course? Was hoping to take my exam in May, thank you again so much and look forward to more videos!
Thank you! I'll consider it. Although I use the official exam guide to research some topics, my videos usually don't fit with the chapters of the official exam guide very well, one video might cover little pieces from 2-3 chapters of the exam guide, for example.
You make such daunting concepts seems so simple by the end of every video. You really bring it all together in such a cohesive way like no other instructor. Thanks, Jeremy!
Hi Jeremy - On the final quiz Q, your answer was the VLAN does not exist on the switch. My question is around creating the VLAN. In these videos, you create the VLANs on access ports: SW(config)#interface range g1/0 - 3 SW(config-if-range)#switchport mode access SW(config-if-range)#switchport access VLAN 10 If you don't want to create access ports in the first place, can you instead do this by changing the two instances of the word "access" above to "trunk"? Thank you so much for responding to these comments!
man, this is the first lesson that has really tripped me up. This covered A LOT. I might need to watch this over a few times. VLANs and trunkports are very in depth, or so it seems right now lol
Take your time to absorb it all. It's hard to catch at first, but VLANs are very important to understand! Also consider checking out some other resources to learn about VLANs from, it's good to hear different perspectives.
@@ataulaleemqureshi608 yeah, very tough. Thankfully I was able to understand the basic principals and pass Jeremy’s quiz at the end. However the next video is another zinger lol when he introduces the commands for STP. This seems more in depth than subnetting or VLANS.
@@onewaydrive_ please let me understand this one first ....watching this video 3rd time hopefully now i will understand next videos i guess i also have to watch 3 times:)have u also learned from another resource?i am just following jeremy sir i guess he is the best ...
I think you do a great job of demystifying a lot of these concepts. I feel like I am actually understanding the concepts and making serious progress toward my CCNA.
These videos have been a lifesaver i cant say thank you enough. Currently in the CCNA course and this has helped me tremendously when i totally didn't understand something. Definitely subbed!
at 15:56 i think the explanation may not be complete. The switch has no clue what VLAN the traffic is intended for. It does assume that the frame is intended for VLAN 30 and, if the MAC address of the destination PC is not in the cache, may flood the frame to the other ports in VLAN 30. The effect is the same - the packet does not reach the intended destination.
I'm assuming that there is regular traffic in the network, so the destination PC's MAC address is in the MAC address table. So, the switch knows that the destination is connected to an interface in VLAN10 (because it's in the MAC address table), but the received frame is in VLAN30 (mistakently, because of the native VLAN mismatch), so it doesn't forward it.
@16:20 are frames in the native VLANs transmitted directly through the switches SW1 and SW2. Without getting through the router R1.(for different VLANs)
Good question! If both the source and destination are in the same VLAN/subnet, the frames don't need to be sent to the router, this is the same for the native VLAN or any other VLAN. If the source and destination are in different VLANs/subnets, the frames have to be sent to the router to be routed. Again, it doesn't matter if one of the VLANs is the native VLAN, the behavior is the same.
@28:00 In Packet Tracer, when you create a sub interface, the main interface will be activated automatically so no shutdown isn't really required. However, it's still a good practice to enable it before creating sub interfaces.
Hi Jermy, I am excited to give my feedback as I have found you awesome. You really know how to TEACH. I was considering to rather discontinue one of my other online academy course and join yours, but I want to know if your course purchase will include the whole course or you are still making the videos?? Thank you..You are BRILLIANT..
thanx a lot for the update, Jeremy your series is amazing i knew that is your course will be completed by the end of the year i hope you could give us the syllabus that you working by (because it is very good), so we could follow it on another complete course thank you again
For Question #5: Using a C3850, if the interface is not connected, the allowed vlans do not show when running "show interfaces trunk" . If you run "show interface g#/#/# switchport", the allowed vlans show under "Trunking VLANs Enabled". FYI
This one was a little bit easier then the first video...I had problem with the LAB cause I like to recreate it and I was unable to ping the other VLANs. However the Pings did work internally in the VLANs..and when i did the simulation the ping look like it was actually flooding which I thought was weird. Yesterday I did try to solve this by trunking but I just confused myself what trunking was. This video help clarify that.
Hey Jeremy, think you can make some videos as a "Day in the life" type since you actually work in the industry? most of us are getting the CCNA and above since we want to work in this field, but something tells me the real world is far more complicated in it's structure. Maybe even tell us your summarized story of how you got to this level? Thanks for all your work, will be purchasing the labs soon!
Mr. Jeremy, thanks so much for your relentless effort. Only God can reward you. In relation to day 17 part 2 lecture, you discuss a topic call ROAS which I enjoyed so much, but is it possible to split the interface as much as the number of VLANs? Asuming I have 10 VLANs. Thanks
Good question! There is a limit, and it depends on the device model, but the limit is very high (300+ subinterfaces). Yes, there would be traffic congestion with so many subinterfaces. That's why ROAS usually isn't used in large networks, instead a multilayer switch is used (I explain them in Day 18, VLANs part 3).
Hi Jeremy, Im really proud with the way that you teaching, it's really make me understand about network CCNA easily step by step, anyway i have some questions for you regarding core switch, What is core switch? What is core switch functions? Does the way to configure core switch it's the same like switch and router?
Hi Jeremy, thanks for your videos. I wanted to ask why untagged frames are important so essentially what benefit does one have if they use native VLANS?
At 21:40 in this video, I explain that a VLAN won't appear in the 'Vlans allowed and active in management domain' section of the 'show interfaces trunk' command if the VLAN doesn't exist on the switch yet, even if you allow the VLAN on the trunk. That's why A is the correct answer for question 5. Even though you configured 'switchport trunk allowed vlan add 10' on the trunk, which allows VLAN10, it doesn't appear in that section of the 'show interfaces trunk' command because VLAN10 doesn't exist on the switch yet.
First I would like to say I love your content and it has helped me tremendously as I’m about to take my CCNA in a few weeks. I had a professor tell me that Cisco ISL supported a little over 1000 VLAN’s but your video says 4094. Either way I don’t think it’s going to be on the CCNA but I am curious as to which one is correct. Thanks again for all you do!
Video's are great for preparing ccna exam. I think you should also provide pdf notes of these slides so it be easy to learn and remember things and can be revise.
