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!
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!

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!
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
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.
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👍🏽
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 🤝
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 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.
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.
still in a computer shop with 300 pesos in my e-wallet to access these free CCNA videos. Sometimes I am racked with self-pity - but I also have to thank God for Jeremy for making these videos not only for free but also professionally. I am still having a hard time with VLANS and I think this is the 3rd time I tried this lab - I will try again later until I master it.
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.
HI @Jeremy. When I try to ping from PC6 (VLAN10) to PC4 (VLAN30) ping does not work. Upon checking in simulation mode, I noticed the ARP reply is coming form R1 to SW2 is getting blocked in SW2 with the message "1. GigabitEthernet0/2 is blocked by STP. The device drops the frame." However ping to any PC in VLAN10 to VLAN10 works. Please advise.
Hi! My guess is that you haven't allowed VLAN 30 on the SW1-SW2 trunk, or you haven't created VLAN 30 on SW2. *Add VLAN 30 to the trunk:* SW2(config)# interface g0/1 SW2(config-if)# switchport trunk allowed vlan add 30 *Create VLAN 30* SW2(config)# vlan 30 SW2(config-vlan)# exit
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.
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.
I am a little confused at why we had to add vlan 30 to the allowed and active in management domain on sw2 and no just add it to the allowed on trunk? Also, if we have to add 30 to the allowed and active in management in domain on sw2, why not add 20 on sw1?
Broski.. the two different switches have their respective v-lans.. SW1 has Vlan 10 and Vlan 30. Just those two Vlans were created on that Switch..... VLAN 20 has no business sending traffic over there. Vlan 20 will send its traffic to the Router via Switch 2, Remember, Vlan 20 and Vlan 10 were created on Switch 2. Switch 1 needs to get to the ROUTER, so since SW 2 is the way to get there, Switch 2 needs to match Switch 1 inter Vlan . Remember, the ROUTER is the KEY. Since SW2 never heard of VLAN 30 being that VLan 20 and Vlan 10 were created on it via access ports, it needs to have a VLan 30 created. I hope this helps.. this is my attempt of helping myself learn this, Lord knows I bumped my head on this for some hours, but now it makes sense..God bless
Hello Jeremy, when i try to open the .pkt i have an error about the version of packet tracer, that never happen before with ur lab :( can u check that please ? thanks in advance
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
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!
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).
Thanks Jeremy, great video. I failed to ping Vlan30 from PC1 at the first try, didn't know I need to and how to create Vlan 30 on SW2. Have to keep practicing otherwise it will be very easily to forget this detail.
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???
I am confused, if we don't need to configure vlan20 on SW2 trunk port because there is no vlan20 connected to SW1 then the logic says that we don't need to configure vlan30 on SW1 trunk port because there is no VLAN30 connected to SW2,,, isn't it ?
Traffic tagged in VLAN30 must be able to pass from SW1 to SW2 to R1 for inter-VLAN routing, so it is necessary to create VLAN 20 on SW2 and allow it on the trunk between the two switches.
That's because you probably haven't configured router's interface, g0/0. So your interface g0/2 on a switch has operational mode: down. That command will only display interface if the trunk is established. Configure router's interface and then check the switch. Also, there's another command that can show you interface configs on switch: show interface g0/2 switchport
Can someone help? What might I be doing wrong? I configured the vlans to the PCs to access ports. I configured the g0/1 of both switches to be trunk ports and native vlan 999. I test connectivity. vlan 30 and vlan 10 connect. But vlan20 doesn't. I bring up the show vlan br, its' there. I do show int trunk, it's also there, native listed correctly. I configured router g0/0 subinterfaces correctly. After that, I returned to g0/0 of the router and did the no shut. Status is up and up. However, vlan 20 is not ping to other networks. Did I need to do the no shut before configuring the sub interfaces?
Hello Jerebear and friends, I was at 9:39, configuring subinterfaces on the router and I named the subinterfaces like this: g0/0.1, 0.20, 0.30. As a result, I wasn't able to ping. Is there a reason for this? Maybe I misconfigured something else because naming the subinterfaces like this shouldn't matter, right??
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
Hi @JeremysITLab in packet tracer lab why didn't you create the native VLAN in the router (creating a subinterface or adding IP address to the interface g0/0)?
@@victorasel2194 i think it's because pc5 must go to the router and move back to the switch, g0/2 on switch 2 allowed vlan 20 (sry for my english i hope you understand)
Hi jeremi. Jeremi I have a question. You said you didn’t add vlan 20 on sw1 because there’s is no host from vlan 20 connected to sw1. But after that you add vlan 30 on sw 2 with no host from vlan 30 conected to sw2. I’m confuse about that. Could someone help this question in case jeremi is busy to respond it. Thank you guys. I think if you don’t add vlan 30 on sw2 it would go trough the router first too. So there is no need to add vlan 30 to switch 2.
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.
Hello Jeremy, I tried doing this from scratch and i'm conflicted with the vlan ip address overlapping. Where my pings from PC 1 won't reach PC 2 etc as the frame is timed out. Could you please help?
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!
Awesome work you are a really good teacher, I have one question about one part (at 17:30 in video) the way to discover which port each pc is connected to ! . In packet tracer I try the show Mac address table but there no listing about example PC1, if I create some traffic it will appear. But my question is, how to find this information if example your try to discover in real situation if the information of Mac address doesn't list those Mac address, there another way to find it ? or another command ? thank in advance
At 2:58, how did you abort the domain name resolution? Usually, in case of a typo, I need to wait for it to finish & then I have to issue the command "no ip domain-lookup" to disable the domain lookup!

hi jeremy. There seems to be a problem in configuration in the lab. at @6:04 you said taht at swtich2 we will only allow vlan 10 and 30 on trunk because vlan 20 is not connected to this switch. However, the diagram says that vlan 20 is connected and vlan 30 is not connected to switch 2. Please clarify if I am making any mistake.
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~!

With Inter-VLAN routing. PC1 will just send the packet to its default gateway and from there the router will be able to send it to PC5. Use simulation mode ping PC1 > PC5 in packet tracer to see it.

@@abdulshaikh1731 By the way, if you're stuck on any of these labs I recommend watching the video and configuring it the same way I do! Then you can see the steps you missed.
When I ping PCs sometimes it fails, after observing the packets with simulation mode it turns to be hugely misprogrammed. I close the tabs of CLIs when I finish writing the commands, could that be the problem?
I wrote "switchport mode trunk" command before int g0/1 interface on sw1. Does it create problem of overwriting n something..? If yes, then how to avoid that..? is there any command which can help us to go back to where we want to, if we missed that command in between and which doesn't create problem of overwriting...?

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.
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 Jeremy. I am not able to ping the vlan 30 from other vlans. Intra vlan routing is happening in vlan 30 but inter vlan routing neither to nor from vlan 30 is not happening. Please help me with it.But inter vlan routing between vlan 10 and 20 is working.
@@sudarsanvaradhan6989 I guess you used the command 'switchport trunk allowed vlan 10,20,30 on G0/2 and 'switchport trunk allowed vlan 10,30' on G0/1, but did you create VLAN30 by using the command 'vlan 30' from global config mode?
If you do 'show interfaces trunk' and g0/2 doesn't appear, g0/2 either isn't configured as a trunk or isn't in an up/up state. For example, perhaps the router interface is shut down.
@@JeremysITLab it worked after i sent the ping on simulation mode lol. another question, sorry lol, if the pings dont send because of a mistake u might have made, and u configure it again does it overwrite the previous one ?
The CLI on the switches is not letting me do multiple vlans with the command "switchport trunk allowed vlan 10, 30" It will show invalid input starting at the 3. I had to use the "add" to get 30 allowed on there. I had to do this on each interface. Not sure why. I redid the lab again mirroring exactly what you did and it still didn't work.
VLAN 20-tagged traffic will never pass between SW1 and SW2. For example, if PC5 pings PC1: PC5 sends the ping to SW2. SW2 sends to R1 (tagged in VLAN20). R1 routes the traffic and sends back to SW2 (tagged in VLAN10). SW2 sends to SW1 (tagged in VLAN10). SW1 sends to PC1. And then the return path is the reverse pattern.
hi Jeremy, excuse me i have a question, we configured the trunk port G0/1 sw2 to sw1, and we allowed only vlan 10 and 30, you said because, the sw 1 doesn´t have to send traffic to vlan 20, because there´s no host on sw 2, however, if u make a ping from pc3 to pc5 the ping works, so that's is traffic or am i wrong? so I hope i was clear, thank u!!
If PC3 pings PC5, the frame is in VLAN30 when SW1 sends it to SW2, and when SW2 sends it to R1. Then R1 tags it in VLAN20, and sends it to PC5 via SW2. So SW1 has no need to have VLAN20 configured.
hi Jeremy wanted to ask if the configuration in a switch are also supposed to be saved by the copy run start command to prevent them from being lost when the switch goes off like a router
I’m so glad there are people like you, who exist on this platform! You’re doing such a huge solid for the community! Thank you, so much!
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.

@@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

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👍🏽
I'm glad you showed Boson. I was hesitant on buying it until seeing this. I think I'l get it when I'm done with this course before taking on the CCNA.
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 🤝
Thank you very much :)
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
Thank you as always for your great comments :)
This was my first lab that i was able to do all by myself correctly . Thanks Jeremy
1:54 access ports SW1
2:49 access ports SW2

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 Edward :)
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
Still trying to figure this out...
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.
Its amazing how easy this looks for you. I cant wait to get on your level!
You'll get there, I'm not so far ahead ;)

@Jeremy`s IT Lab This is first ever video without a dislike
still in a computer shop with 300 pesos in my e-wallet to access these free CCNA videos. Sometimes I am racked with self-pity - but I also have to thank God for Jeremy for making these videos not only for free but also professionally. I am still having a hard time with VLANS and I think this is the 3rd time I tried this lab - I will try again later until I master it.
pinoy?
I forgot to add vlan 30. that's why I was failing in some pings. It was a great lab, thank you Jeremy
thank you mr jeremy we here in iraq depend only n your videos to pass ex. and i hope i will get to your level one day soon
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 .
Thank you :)
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.
HI @Jeremy. When I try to ping from PC6 (VLAN10) to PC4 (VLAN30) ping does not work. Upon checking in simulation mode, I noticed the ARP reply is coming form R1 to SW2 is getting blocked in SW2 with the message "1. GigabitEthernet0/2 is blocked by STP. The device drops the frame." However ping to any PC in VLAN10 to VLAN10 works. Please advise.
Hi! My guess is that you haven't allowed VLAN 30 on the SW1-SW2 trunk, or you haven't created VLAN 30 on SW2.
*Add VLAN 30 to the trunk:*
SW2(config)# interface g0/1
SW2(config-if)# switchport trunk allowed vlan add 30
*Create VLAN 30*
SW2(config)# vlan 30
SW2(config-vlan)# exit
Had the same issue, thank you
You Packet Tracer Labs are awesome!!!!!!!!
Thank you ;)
Hello Jeremy, I would like to appreciate all the helpful videos you are sharing us. I never enjoyed learning to this extent. Thank you very much!
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.
It is really helped! U are my savior!
I did this lab 3 times alone and once following with the video but i cant get the pings. I tried closing and restarting PT and no luck yet
7:35
We configure vlan 30 on switch two?! Why? Is it the same thing as doing it on switch one?
You are God’s sent, Sir Jeremy
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.
You the man, Jeremy!
Thank you! YOU the man!
I am a little confused at why we had to add vlan 30 to the allowed and active in management domain on sw2 and no just add it to the allowed on trunk? Also, if we have to add 30 to the allowed and active in management in domain on sw2, why not add 20 on sw1?
Broski.. the two different switches have their respective v-lans.. SW1 has Vlan 10 and Vlan 30. Just those two Vlans were created on that Switch..... VLAN 20 has no business sending traffic over there. Vlan 20 will send its traffic to the Router via Switch 2, Remember, Vlan 20 and Vlan 10 were created on Switch 2. Switch 1 needs to get to the ROUTER, so since SW 2 is the way to get there, Switch 2 needs to match Switch 1 inter Vlan . Remember, the ROUTER is the KEY. Since SW2 never heard of VLAN 30 being that VLan 20 and Vlan 10 were created on it via access ports, it needs to have a VLan 30 created. I hope this helps.. this is my attempt of helping myself learn this, Lord knows I bumped my head on this for some hours, but now it makes sense..God bless
Hello Jeremy, when i try to open the .pkt i have an error about the version of packet tracer, that never happen before with ur lab :( can u check that please ? thanks in advance
Same here
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
Am back from the holidays (and a hospital stay yay), opening this lab video made me metaphorically roll up my sleeves in preparation
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.
Yes, I've the same problem. I just added a vlan 30 on switch 2, So it was allowed and active in management domain
Glad to know it wasn't just me. Thanks,@@unimatelunimatel6175.
@@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!
@@oscarm534 I did the exact same thing and when I saw your comment I knew immediately. Thanks!
Day 17 Lab was awesome! Thank you Jeremy!
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).
Thanks Jeremy, great video. I failed to ping Vlan30 from PC1 at the first try, didn't know I need to and how to create Vlan 30 on SW2. Have to keep practicing otherwise it will be very easily to forget this detail.
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???
I am confused, if we don't need to configure vlan20 on SW2 trunk port because there is no vlan20 connected to SW1 then the logic says that we don't need to configure vlan30 on SW1 trunk port because there is no VLAN30 connected to SW2,,, isn't it ?
Traffic tagged in VLAN30 must be able to pass from SW1 to SW2 to R1 for inter-VLAN routing, so it is necessary to create VLAN 20 on SW2 and allow it on the trunk between the two switches.
@@JeremysITLab Thank you Jeremy
I Love you Jeremey ❤ I can’t thank you enough for what you do.!

I love them.
Thanks Jeremy.
Jeremy, you are a Great teacher.
Thank you Raivel!
why cant I display the "show interface trunk" of g0/2 on sw2?
for some reason it always shows g0/1...
That's because you probably haven't configured router's interface, g0/0. So your interface g0/2 on a switch has operational mode: down. That command will only display interface if the trunk is established.
Configure router's interface and then check the switch.
Also, there's another command that can show you interface configs on switch:
show interface g0/2 switchport
@@neksi5 Thanx a bunch!
Can someone help? What might I be doing wrong? I configured the vlans to the PCs to access ports. I configured the g0/1 of both switches to be trunk ports and native vlan 999. I test connectivity. vlan 30 and vlan 10 connect. But vlan20 doesn't. I bring up the show vlan br, its' there. I do show int trunk, it's also there, native listed correctly. I configured router g0/0 subinterfaces correctly. After that, I returned to g0/0 of the router and did the no shut. Status is up and up. However, vlan 20 is not ping to other networks. Did I need to do the no shut before configuring the sub interfaces?
Hello Jerebear and friends,
I was at 9:39, configuring subinterfaces on the router and I named the subinterfaces like this: g0/0.1, 0.20, 0.30. As a result, I wasn't able to ping. Is there a reason for this? Maybe I misconfigured something else because naming the subinterfaces like this shouldn't matter, right??
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
It seems there's a problem with routing. Check the configurations for the connection between R1 and SW2.
How do you figure out what the last usable address is. What video was that in? Submetting maybe?
Yes, subnetting.
Hi @JeremysITLab in packet tracer lab why didn't you create the native VLAN in the router (creating a subinterface or adding IP address to the interface g0/0)?
I still dont understand why he didnt add VLAN 20 as an allowed trunk on SW2. I get that on SW1 no hosts are connected to it but why not on SW2.
same confusion here 🤔
@@victorasel2194 i think it's because pc5 must go to the router and move back to the switch, g0/2 on switch 2 allowed vlan 20 (sry for my english i hope you understand)
Because VLAN 20 doesn't need to go through interface g0/1, that's why it wasn't added.
Hi jeremi. Jeremi I have a question. You said you didn’t add vlan 20 on sw1 because there’s is no host from vlan 20 connected to sw1. But after that you add vlan 30 on sw 2 with no host from vlan 30 conected to sw2. I’m confuse about that. Could someone help this question in case jeremi is busy to respond it. Thank you guys. I think if you don’t add vlan 30 on sw2 it would go trough the router first too. So there is no need to add vlan 30 to switch 2.
Hosts in VLAN 30 need to be able to reach R1, so VLAN 30 needs to exist on SW2.
Quick question. At 6:00-6.20 why was Vlan 30 allowed and not Vlan 20. I ask because Switch #2 doesn't have a Vlan 30 host attached
I have the exact same question
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.
Thanks a lot sir!!!! these lab exercises really help to clarify such complex topics.
Thank you! Glad to hear that :)
18:30 Yes sir you did mention that about the CLI command : #show mac address-table
Thanks! Good memory!
Hello Jeremy,
I tried doing this from scratch and i'm conflicted with the vlan ip address overlapping. Where my pings from PC 1 won't reach PC 2 etc as the frame is timed out. Could you please help?
Try watching my video and follow along! Do the same configurations that I do
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.
Sir, you deserve more but I can't do more than a comment, share and subscribe!
I mean it.
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!
Just tested it myself, and you don't need to allow VLAN 20 on the trunk. My guess is you forgot to manually create VLAN 30 on SW2.
@@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!
Awesome work you are a really good teacher, I have one question about one part (at 17:30 in video) the way to discover which port each pc is connected to ! . In packet tracer I try the show Mac address table but there no listing about example PC1, if I create some traffic it will appear.
But my question is, how to find this information if example your try to discover in real situation if the information of Mac address doesn't list those Mac address, there another way to find it ? or another command ? thank in advance
At 2:58, how did you abort the domain name resolution?
Usually, in case of a typo, I need to wait for it to finish & then I have to issue the command "no ip domain-lookup" to disable the domain lookup!

and its giving me time out which was interesting that i did everything right so i went into simulation mode and what happening is pretty interesting so the icmp going out of the pc7 out to the switch 2 and to the router which he sends it to switch 1 and the switch 1 send it to the pc4
now replying to that the pc4 sending the icmp echo to the switch 1 the switch 1 to switch 2 and then to the router the router resend it to the switch 2 and for some reason the echo is sent back to switch 1 and recived only by pc's on vlan 10 connected to switch 1

hi jeremy. There seems to be a problem in configuration in the lab. at @6:04 you said taht at swtich2 we will only allow vlan 10 and 30 on trunk because vlan 20 is not connected to this switch. However, the diagram says that vlan 20 is connected and vlan 30 is not connected to switch 2.
Please clarify if I am making any mistake.
Hi Athar,
I didn't say "because VLAN 20 is not connected to this switch", I said "there are no VLAN 20 hosts connected to switch 1".
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~!
Thank you Jeremy....could you do a CCNA security course
CCNA security was retired by Cisco on February 24th of this year, it doesn't exist anymore!

Hello Jeremy thanks alot for all you do.Please how do I finish the lab in this video,can't find the link in your Bio section.Please can anyone help
hey Jeremy. in the lab, after I properly configure SW1 & SW2 as a trunk, I am mot able to see the trunk interfaces after show interface trunk command?
What commands did you use to configure them as trunks?
@@JeremysITLab
SW1(config-if)#switchport trunk allowed vlan 10,30
SW1(config-if)#sw
SW1(config-if)#switchport t
SW1(config-if)#switchport trunk n
SW1(config-if)#switchport trunk native v
SW1(config-if)#switchport trunk native vlan 1001
SW1(config-if)#end
this is the command for SW1 then I used show interfaces trunk. but I can't see the trunk table.
How will PC 1 connect to PC 5 if Vlan 20 is not allowed on trunk port on Switch 1
With Inter-VLAN routing. PC1 will just send the packet to its default gateway and from there the router will be able to send it to PC5. Use simulation mode ping PC1 > PC5 in packet tracer to see it.

I meant maybe because I close the CLIs right away after writing it causes the commands to get deleted or something.
I wrote "switchport mode trunk" command before int g0/1 interface on sw1. Does it create problem of overwriting n something..? If yes, then how to avoid that..?
is there any command which can help us to go back to where we want to, if we missed that command in between and which doesn't create problem of overwriting...?
hi jeremy pls let me know , if i do the same config (from my memory ) as you do in my packet tracer, I made mistakes but , I dont know how delete the config (error in the line command ) and start from the begining (ie.. i always open new file and start again instead clear the router configuration.

'write erase' deletes the startup config. Then you can do 'reload' to reset the device with the factory default configuration.

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.
Sorry to hear you didn't like it, I think it's great!
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 Jeremy. I am not able to ping the vlan 30 from other vlans. Intra vlan routing is happening in vlan 30 but inter vlan routing neither to nor from vlan 30 is not happening. Please help me with it.But inter vlan routing between vlan 10 and 20 is working.
Hello Sudarsan! Perhaps you forgot to create VLAN30 on SW2? Use 'show vlan brief' and check if VLAN30 exists on SW2 :)
@@JeremysITLab Yes I did create vlan 30 on SW2 on interface g0/2. But still it's not working.

@@JeremysITLab yes.I rectified my mistake .Thank you so much for your response.
hi jeremy, when i try to view the trunk on g0/2 it only shows g0/1, just to make sure vlans 10, 20 and 30 are allowed on g0/2
If you do 'show interfaces trunk' and g0/2 doesn't appear, g0/2 either isn't configured as a trunk or isn't in an up/up state. For example, perhaps the router interface is shut down.
@@JeremysITLab it worked after i sent the ping on simulation mode lol.
another question, sorry lol, if the pings dont send because of a mistake u might have made, and u configure it again does it overwrite the previous one ?
Wow this is nice, thank you Jeremy, you are very good at doing it.
Thank you!
Why didn't we trunk the G0/2 interface in SW2 and allow vlan 10,20 and 30?
since the router itself has no ip on g0/0 , how would we about reaching the internet?
Do you configure DHCP on the router? How else would the PCs get their IP addresses?
The PC's Ip addresses have been configured manually in the lab. You don''t need to worry about them
very good, this really helps to build up hand on experience
The CLI on the switches is not letting me do multiple vlans with the command "switchport trunk allowed vlan 10, 30" It will show invalid input starting at the 3. I had to use the "add" to get 30 allowed on there.
I had to do this on each interface. Not sure why. I redid the lab again mirroring exactly what you did and it still didn't work.
Did you try it without the space after the comma, as I did?
@@JeremysITLab Oh I see. I missed that. Thanks!
Hi jeremy, allow me to ask u a stupid question, why SW1 gi0/1 and SW2 gi0/1 no need to set trunk allowed VLAN 20?
VLAN 20-tagged traffic will never pass between SW1 and SW2. For example, if PC5 pings PC1:
PC5 sends the ping to SW2.
SW2 sends to R1 (tagged in VLAN20).
R1 routes the traffic and sends back to SW2 (tagged in VLAN10).
SW2 sends to SW1 (tagged in VLAN10).
SW1 sends to PC1.
And then the return path is the reverse pattern.
hi Jeremy, excuse me i have a question, we configured the trunk port G0/1 sw2 to sw1, and we allowed only vlan 10 and 30, you said because, the sw 1 doesn´t have to send traffic to vlan 20, because there´s no host on sw 2, however, if u make a ping from pc3 to pc5 the ping works, so that's is traffic or am i wrong? so I hope i was clear, thank u!!
If PC3 pings PC5, the frame is in VLAN30 when SW1 sends it to SW2, and when SW2 sends it to R1. Then R1 tags it in VLAN20, and sends it to PC5 via SW2. So SW1 has no need to have VLAN20 configured.
hi Jeremy wanted to ask if the configuration in a switch are also supposed to be saved by the copy run start command to prevent them from being lost when the switch goes off like a router
Yep, same as a router! Make sure to save when you're done with your configurations (I should probably show that at the end of each lab).
