Glad these lab instructions exists. I was SO close to getting it on my own and eneded up finding this out the hard way: no shut does NOT work on sub-interfaces! Besides my error, the instruction from the previous lesson really made things clear. Awesome work, Jeremy!
I am so thankful for these labs. I particularly like to go outside of the lab instructions and run commands I learned in the previous videos to keep them fresh. This lab in particular really had me stuck. I was pretty confident I had done everything correct but was unable to ping any PCs in vlan30 from PC7, PC6, and PC5. Spent a good bit of time making sure I configured everything. Went through all the steps I had done 3 times, looked at all the show outputs to see what I was missing and couldn't figure it out. Watched the video. Vlan30 wasn't on SW2 because I didn't even think about adding the vlan if there wasn't any PCs in vlan30 connected to the switch. Probably, won't forget to do that ever again after the headache I gave myself. Thanks again for making this course free and accessible!
I ran into that same problem, If switch 2 doesn't need to send any vlan20 traffic then why should switch 1 need to send vlan 30 traffic if there is no vlan 30 accessing it
@@ChristianRuales it's because sw2 does not know about vlan30 existence, you should add a simple {vlan30} command so sw2 will recognise it then it can sent traffic to the trunk port.. check 6:40
Same man, I made the same mistake and spent 20 mins troubleshooting haha, I managed to work it out myself though. Mistakes are such a useful and important part of learning!
Thank you so much Jeremy i increased the number of Switches and managed to make it work, after watching ur video and then successfully completing the task, I see trunking and switching a little bit easy, thanks bro👍🏽
Cant thank you enough for your videos! This comment is for anyone who was unable use PINGs to test interconnectivity. I totally forgot to configure G0/2 on SW2 and spent over an hour going over the configurations again. For me, i had to take a critical look at the traffic paths and check each interface along that path. Only then was i able to determine where the issue was.
This series is very helpful for those who don't have money to join ccna classes..Your doing great job sir Tysm for sharing this new ccna series with us 😊 & your teaching style is fabulous. Every concept teached by you is very simple & understandable..😎 we are all waiting for your next video.. Be safe & take care sir 🤝

Hello Jeremy! Cannot thank you enough for these amazing videos. Fantastic job. I would like to ask why we allowed VLAN 30 connected to SW1 and not VLAN 20 connected on SW2 through the trunk? Is that part of the scenario and needed to do it like that exactly? Whatever the VLAN 30 is for SW2, VLAN 20 is exactly the same for SW1. I am sorry, I might missing something here but it would really help to to get this answer. Thanks a million
@@tferuh I came across with the same question but I figured it out… As VLAN20 is directly connected to it’s default gateway (R1) no need to configured in S2. Although VLAN30 needs to be connected to R1 to perform trunking it should be connected to SW2’s G0/1 interface. I hope this helps! All thanks to Jeremy!
Great video Jeremy. I did the lab by myself and encounter an issue with packet tracer. I did everything correctly and the pcs were not able to ping each other. after going through the configuration a few times I decided to close packet tracer and open it again just in case and that did the trick. just in case someone is having the same issue.
Why is VLAN 20 not allowed on SW2? I re-watched the day 17 lecture but couldn't find the answer. SW2 could send VLAN 20 traffic on the trunk if a host in VLAN 20 pings a host in VLAN 10 or 30
i had the same question i was confused as well, i guess the answer is becuz when it's sent to others, there's the vlan tag, and the vlan 20 tag wont be required? im not sure either. sorry
if you are talking about 6:20, it's beacause he's talking about interface G0/1 of the switch, not the entire switch. vlan 20 will never send any trafic over that trunk port, since there are no vlan 20 hosts connected to switch 1.
Vlan 20 can go straight to router, but vlan 30 and 10 need trunk to get to router. Makes it a bit confusing as there is also another vlan 10. This easiest way to understand it.
@@lumen_synths It is allowed on SW2, but only in interface g0/2. It's not allowed on interface g0/1 because there is no need. All vlan 20 traffic will travel to the router and the switch will change the vlan of the packet to the destinations vlan.
I am dumbfounded this time, I really don't know what other good comment I can use to qualify this extraordinary teaching. I had a lot of tough time in vlans for long but this lab just explained it all I never knew it's as simple as this. In fact, nothing's difficult to learn if you have the best tutor . Keep it up and thank you
Hi, i am so confused. Why do we allow VLAN 30 on SW2? We don't allow VLAN 20 on SW1 because there's no host in VLAN 20 connected to SW1, i get this but there's also no host in VLAN 30 connected to SW2 but we still allow it in the trunk. I'm lost here.
Bcoz SW2 is connected to R1 with a router on a stick so it is necessary to add a vlan trunk port which vlan is in use, and we don't allow vlan 20 is in SW1 because there is no host connected to SW1 Interface, if vlan 20 host wants ping the in SW1 they should have to go through Router (ROAS), bcoz SW1 do not have VLAN 20 Created. Thank you 😊
Because sw2 connected to router r1. R1 requires all vlan logical connection to do inter-vlan routing, so all vlan in the network has to be configured in this interface. CMIIW
Hi Mr. Jeremy, am new here all the way from Sierra Leone. I have just downloaded your playlist on CCNA and have watched upto day 5 and am really in love with it. Thanks so much, God bless and hope to see more videos as you said.
Thanks alot Jeremy for the videos. Your videos are so easy to understand. Even who don't have much knowledge about ccna can get great knowledge from your videos .
Slowly catching up and glad to see a little insight to netsim. I purchased the kit yesterday but have not delved into either one(exam or net) yet so this was good to watch.
Hi Ed, thanks for your support as always! Good move on getting ExSim and NetSim. I recommend saving ExSim until you have finished studying all of the exam topics (www.cisco.com/c/dam/en_us/training-events/le31/le46/cln/marketing/exam-topics/200-301-CCNA.pdf), I think it's most effective as a tool for final preparation before the exam. NetSim, however, is a great tool to use along with a book/video course! :)
@@JeremysITLab also glad to get your emails about the 25% off. That made buying the kit all the easier. I dabbled with both but I need to get caught up on the rest of your videos and start digging into the Boson software.
I could not get the PCs in VLAN 30 to connect with any others on the other subnets in this exercise, but I got the others properly configured. I'm learning a lot with these labs and lectures.
@@unimatelunimatel6175 I banged my head against a wall for 30min on this lab. I usually do the labs and don't watch the lab video unless I need help. I could not figure out what I was doing wrong. Went back and watched the video and still missed it. Then I decided to close the packet tracer lab and start from scratch and rewatch the video and then I saw it and it clicked. I was missing vlan 30 in Sw2 the whole time. Facepalm!
Thanks Jeremy for your time, this was well-explained. I will have to watch this video again in other to gain better understanding about the process of VLAN trunking.
Hello! First of all I want to thank you for this course! it's extraordinary! I've done this lab 3 times and I can't get past a simple problem. PCs do not communicate with PCs in a different VLAN. communicates only with PCs from the same vlan .. where is the problem? trunk ports seem ok on both sw's
The Boson netsim looks really helpful, thanks for showing it. I might have to try that after ccna when studying for ccnp encore (hopefully will have a job by then to be able to justify paying for it haha).
if anyone unable to ping different vlan like from vlan 10 to vlan 30 pc , make sure you configured default gateway of each pc, it was took my whole day.
I did an almost perfect lab without watching the video. I hesitated to create VLAN 30, but also tempted to create the vlan on it and damn it, I should've done it! at least, this will something that I won't forget. Anyway, thanks for your video!
A packet tracer glitch caused me to spend way more time on this lab than I needed, but at least going through the configurations a ton of times made me more comfortable with setting up vlans.
Hi Jeremy, Thank you so much for one of the best and amazing CCNA course, clear introductions, instructions and very useful labs!!!! I followed your recommendation about Boson, and would like to share my experience. Two days ago I purchased Boson NetSim, and must say my first impression is ...very disappointed... Boson should improve many things, instructions are not clear, very confused, detailed topology (interfaces, ports numbers) are part of the introduction only, not as separate topology, PC configuration is in CMD, some of the labs are already configured and that is not introduced on the beginning of the lab instructions... Lab designer is very poor, Packet tracer, GNS3, VIRL are far better than this one. Honestly, would not recommend Boson NetSim for lab practicing, I think they should learn from you how to design the labs... All the best and keep up the good work!!! S.
Thank you Jeremy for another amazing video. I did the practical via packet tracker using the last lecture video and I got it. Could share the pkt file for review if you wouldn't mind.
Here is new link if you're having difficulties with access to the previous link. drive.google.com/file/d/1YAIlUQ9Wd22g7AqeU9hOjkkI1fi-9jsH/view?usp=drivesdk
Hi Jeremy, thank you so much for this course i find it so much easier to follow this then read the books on this material. i have signed up to your email list has there is no link to the lab in the description. i hope you can send this through to me as i am trying to get through as much videos as i can during the lock down. thank you again.
wow Jeremy,Thanks i was doing the lab by myself and it didn't ping other networks beside VLAN 10 and no matter what i did it didn't add the VLAN to the Managment domain(when you do- "sh int trunk". anyway i just needed to add the vlan via a cmd- "int g0/1>>>VLAN 30" same thing on SW2 only diffrent vlan i can't belive that i missed that tiny detail! anyway thanks again~!
Hi, first of all, thank you so much for your valuable video. For two days I was trying to do the same lab but I wasn't a success there in the video you didn't show pc configuration in the packet tracer. tried to communicate with different VLAN so there needs to put default gateway IP. thanks once again for your video and I'm following your course.
@@JeremysITLab Thank you so much for your concern and suggestion, I didn't download the lab. I tried to do that also but I couldn't find the file. when clicking on the link it redirects to me natcad site.
Hi Jeremy, thanks again for providing the link to the pre-made labs, it definitely helped a lot. Question, why does the ping from VLAN 10's PC7 to VLAN 30's PC3 have to go through the router if there is a trunk established for VLANs 10 & 30? Is it because they aren't in the same VLAN? Just want to make sure so I understand. Thank you!
The switch won't forward data from a PC in VLAN 10 to a PC in VLAN 30. The trunk means that traffic in both VLANs can be forwarded over that specific link, but that doesn't mean the switch will send the VLAN 10 traffic to the VLAN 30 PC.
Hey @JeremysITLab I followed exactly every step in the video because PC5 wouldn't successfully receive or send pings to the other PCs. I figured out that you do have to 6:09 allow VLAN 20 on SW2 in order for it to ping (maybe you have to configure it for it to reach the router? or it's a packet tracer glitch) . I know you explained that you wouldn't have to but like I said even when I followed step by step it wasn't working. I don't know how nobody else caught this but I wanted to point it out as my thanks for your videos!
@@JeremysITLab it did work when redoing it your way but I swear i added the vlan30. It is probably because I didn't allow trunk vlan 10,20,30 for SW2 interface G0/2 since I don't recall that. Thanks again!
I had problems with the vlan 30 on SW2 until I didn't create this vlan there. Were it not for this video, I wouldn't be able to come up with the solution, thanks!
Hi Jeremy's. thanks for gives this opportunity to get familiarized with Cisco products. On SW1you didn't add the VLAN 20 (G0/1) because you said that there is no VLAN 20 interfaces connected to SW1, however you add VLAN 30 to SW2 (G0/0) when there is no VLAN 30 interfaces connected to SW2. Could clarify. Thanks.
Hello, I am close to wrapping up this excellent video series. I do plan on downloading the Boson Netsim and practicing commands and lab configurations. Is there anything else you recommend to study before taking the exam? Any books or practice exams?
Yes you will definitely need a set of books (I recommend Cisco's official guides by Wendell Odom) or another video course, my video course isn't finished yet so there are MANY topics that I haven't covered yet.
Hi Jeremy, first of all thank you for these in depth & amazing lectures. I have learned CCNA before but with your course i am always learning something new with every lecture. I have a question, you created an empty VLAN 30 on SW2, but isn't it important to create a similar empty VLAN 20 on SW1 ?? Why so?
SW2 needs VLAN30 because VLAN30 traffic will be sent to R1 via SW2 for inter-VLAN routing. However, no VLAN20 traffic will ever be sent to SW1. There are no end hosts in VLAN20 connected to SW1, and the router isn't connected to SW1 either, so it's unnecessary.
Wow this is the best complete course! could you please let us know what is the packet tracer version that you are using. I installed version 7.2.1 but i couldn't open the labs you have provided. Thank you !
Hey guys Im trying to catch up but stuck here ,I can ping from Vlan 10 to Vlan 10 but cant ping from Vlan 10 to another pc in a different Vlan ....And thanks a lot Jeremy so glad to have you
very helpfull videos i have one question here.........why vlan 30 is allowed on SW2 as there is also no host for vlan 30....same as in the case of SW1 for vlan 20 ? Is it necessary to allowed. PLEASE answer me
Hi Jeremy, I am not sure if you will reply to this comment but I really hope you do. First of all, thank you for sharing this course on RU-vid for free. You are a life saver. Secondly, I am having trouble accessing the packet tracer labs. I can access the labs on your google drive but they are not similar to the ones you are using or not clearly labeled. Could you kindly assist me. Thanks.
There are many more videos, and many more topics to come. Check out the official exam topics list to see which topics have been covered and haven't (most haven't): learningnetwork.cisco.com/s/ccna-exam-topics
Thank you so much for your understandable teaching and efforts for us!! Btw can u suggest which certificates we need to have to make career with networking ? Thank for your reply Jeremy sensei.
Thanks for ur all video. I have CCNA exam on this thursday, but not yet covered for all, so scared, hahaha Do we have the ACL review on your video? i heard that is the important subject.
hi jeremy, why in the day 16 lab you configure the 3 connections between router and switch as access ports, but this lab as a trunk port? Hope you'll answer, Thanks!
Vlan 20 direct to router, not connected to R1, only need to go trhough R1 not SW1 as vlan 20. Vlan 30 and 10 however needs to go through both switches, so thats why need to be allowed all on sw2, but no need for vl20 on sw1.
Thank you very much Jimmy for this lab please can you tell us how we can configure the native vlan in the g 0/0 on the router and in the sub interfaces. Thank you
Dear Jeremy 👋 Learning alot from your uploads I have configured the same topology and done the configuration as instructed by you. But pc's in the vlan 30 are unable to ping their default gateway but pc's of other vlans can ping 192.168.1.190. When i configured the vlan 30 on the switch2, pc's in the vlan 30 started pinging their default gateway 192.168.1.190
Hi Jeremy. I want to compliment you on a fantastic job you are doing with providing us with this course. I have been learning much. I am having an issue with the Boson NetSim. As your course is FREE, I assumed that ALL portions of the course are free. But, when I click on the Boson NetSim, all of the Labs are locked. You did not mention that we had to purchase anything. The Load Lab option is greyed out. Please advise.
My course will always be free, however NetSim is a separate product sold by Boson SoftWare, I can't offer it for free. I just recommend it to those who want/can afford extra study resources. I used Boson's products (ExSim and NetSim) when studying for my CCNA and CCNP so I always recommend them!
@@JeremysITLab Thanks for the quick reply. I figured as much, but I know better to ask, then assume. Thanks again, for providing us with this detailed CCNA course. Couldn't have come at a better time.
I have a question. We just set trunk allow VLAN10 and VLAN30 between sw1 and sw2. Why pc5 in vlan 20 can ping pc3 in vlan 30？ Any help will be appreciated。 thank you
when i type in "do show interfaces trunk" it drops down and shows me nothing. i even closed packet tracer, opened and reopened the lab, nothing is working. why do you think this is???
There is an error in this packet tracer lab. PC5's VLAN20 is listed with a network IP of "10.0.0/64/26" You can even see this in the video. Should be "10.0.0.64/26" Doing the lab right now, k thnx.
and if it possible can you make 2 labs one with no configuration at all i mean without subnetting and giving hosts ip and default gateway ..., help a lot in reviewing . and the other is the same but with configuration , i really like starting from 0
this may be a dumb question, but is BOSON netsim free? Also, thanks for the vids sir Jeremy, i am already CCNA trained but i figured i need more knowledge haha
@@JeremysITLab thank you sir jeremy! i also have 1 question, what's the risk of using native vlan? one of my trainers before said that native vlans can be used to decrease bandwidth usage which means increasing the performance of the network
Hope you can answer this question for me. Let's assume VLAN20 is not with SW2 , insted We put it with SW1 without changing anything else. The question is, would we need to configure Switches to have Vlan 20 with 10 and 30 ? and why
The trunk between the switches needs to allow any vlans that need traverse this segment, so if you move vlan 20 and the connected host onto SW1 you will need to configure SW1 with vlan 20 and also configure the trunk to allow vlan 20 across so it can get to the router R1 (hint: follow the PDUs in Simulation mode when pinging hosts in different vlans) Test: think about whether you will need to also have vlan 20 configured on SW2 with your new scheme.
I dont understand the whole ALLOW specific Vlan configurations on the switch. I did a few labs and I had to allow ALL Vlan's on the switch interface for it to work. I just understand when/which VLANs to allow.
