sir, my little advice to you to create page/group of Free Complete CCNA Course on Facebook or social media platforms. and upload all your videos. so more people will know about this channel. 😊 ♥️ from India.
for anyone actually taking the ccna. the majority of the questions focus on knowing: subnetting by heart, everything about switchports, wireless, ipv6, and misc troubleshooting a variety of things. the questions also change to focus on what you are weakest at. so if you do bad on subnetting, like me, you will receive many more subnetting questions. the test is not hard itself but cisco exams are mostly trick questions which feels scummy for a knowledge test. feels like they made the wording as difficult as possible to boost their prestige . you will fail questions over grammar and word choice.
Thank you for the information as I’m about to take my first attempt and hopefully my last attempt at the CCNA exam in July. Feel free to pass along any other tips as well. Congratulations on your achievement!
If you made it here keep going. I broke on this day a week ago.. took me 3 days before i moved on. I know it seems hard but we can do this, we can change our lives. Keep going
The examples you give of why the topic is necessary is always the best part of these videos. Most just go on to talk about it because it's on the exam, but you give real world examples.
I just passed my CCNA this morning with an 897 !!. I am sincerely grateful to and everything you have done . I still want to buy that beer and wagyu one day when Japan opens lool. I think you have an amazing gift as a teacher and I wish you luck in all you do . God Bless !!!
Congrats, and that's a solid score! So glad to hear you passed, and I hope you celebrated! I hope you know what you're committing to with the wagyu, it's not cheap! Haha
@@JeremysITLab I know what I am in for man and its totally worth it lol. Other than yt, is there any way to correspond with you if I had any questions? I plan on studying ccnp and I would love to reach out in the future if you dont mind.
This helped me memorize which commands to use: - Privileged Exec mode: etherchannel (show etherchannel) - Global Configuration: port-channel - Interface Configuration: channel-group/channel-protocol If I'm not mistake, you can only use one type of command at each level.
Here studying on Christmas eve before dinner! I wanna get my CCNA by the end on January. Thank you once more for your incredible videos, Jeremy. Happy Holidays my friend.
Hey Jeremy, how are You ? I started learning networking about two months ago, and it's very clear with your explanations. As I progress through the chapters, I find it more interesting and fascinating the way each problem is solved with technology. Also, I wanted to say thank you for sharing all your knowledge with us. Plus, bonus you allow me to greatly improve my English. (because I am Belgian). Finally, I hope to visit Japan one day, I love this country👍
just a note on the Boson Quiz question but 'channel-group 1 mode on' is a valid command as long as both switches are using the 'on' mode. the reason answer B is correct is because you cant mix the LACP and PAGP protocols on an Etherchannel, they must be the same on both switches.
Am From India. Karnataka. What Teaching! You are Great Skills and Every one Easily understand. We Proud. You are such humble person. Thanks for Giving good containt. Keep it up sir.
Thank you for using simple english sir! English is not my first language but your teaching covers it well without complicated english words. once again,Thank you very much.
@@JeremysITLab Oh yes I did! Sorry for late replying J. Anyway I can contact you privately? I'd like to tell you my story...And it's a hell of a "story" ;-)
Thank you so much, Jeremy. Also I love that are still concerned about "Channel failed to load". Once they finally reveal themselves it's going to be a huge thing!!! lol
Hey Jeremy I've been watching your videos quite a bit but decided to check out another RUclipsrs ether channel video. Man, you make certbros look like a joke Thanks Chris
8:30 I feel so smart for some reason haha, i was just reminding myself how VLANs are virtual and make something physical into different groups and how these 4 connections are grouped as 1 and made virtual. It's like the opposites
Very clear and concise course you have here, I'm enjoying it very much. However a couple of things to mention here. 1. Talking about load balancing in this context - while common - a bit misleading. LACP does not take into account the load on the other legs of the aggregated link, it just determines the appropriate leg to use based on the 3 named methods. EtherChannel contains no actual load balancing algorithm either. Strictly speaking link aggregation is load _distribution_, not balancing. 2. Aggregating 4 links does not strictly speaking create a single link with 4 times the bandwidth either. Again, the traffic isn't balanced, just distributed across the available links based on the named rules but without considering the existing link load. The max traffic speed between any 2 devices over an EtherChannel link = the speed of a single physical link involved in the EtherChannel. In real-life network you may well have a 4-leg EtherChannel and notice 80% utilization on 3 legs but only 5% in the fourth. Actual load balancing requires intelligent devices that constantly monitor the traffic, and re-direct it over different links in case of congestion. Just wanted to bring this up, as I've lost count how many times I've had to explain it to less-than-happy network admins. Other than that, absolutely fantastic series :-)
Yeah I'm aware of how EtherChannel works. Cisco gives a pretty good explanation of how EtherChannel load-balancing works on IOS/CatOS here: www.cisco.com/c/en/us/support/docs/lan-switching/etherchannel/12023-4.html
@@JeremysITLab Yeah I had no doubt - just considered it worthwhile to clarifying this to the people who follow the course. Explaining this to an irate budding NetAdmin who's not happy when the traffic over his server's LACP link is unbalanced loses its appeal after the 11th time or so :-) Funny enough Cisco agrees; the second sentence in that page says "...allows load SHARING of traffic...". That's the only time, tho' - after that it's about "balancing". My best guess is that that the marketing ppl butted in. "Load sharing" and "load balancing" are two very different concepts, but one of them sounds better on the brochures...
Quiz 2, I am wondering if we really need to know these config flags by heart for the CCNA? Have you experienced any questions like that on the exam? Great video as always!
Hey Jeremy, thx for the course, it s so good! Could you make a post on which topics are not covered yet ? So we can plan our learning better/know exactly what we have to look for? It would be appreciated so much! Ty!!
Will do! You can also check the topics out here and see which you haven't learned yet: www.cisco.com/c/dam/en_us/training-events/le31/le46/cln/marketing/exam-topics/200-301-CCNA.pdf
You are amazing at presenting. Even if you might not have the time or inclination to write out a full course on something in the future, I wish you would do the voiceover portion of some of the other courses I've taken. I can put your videos on 1.5x speed (like all of the life/study-hackers claim to) and still understand everything perfectly, which is very rare for me. Thanks for the great stuff!
Hi Jeremy, I read the answer explanation of the Boson Ex-Sim bonus question, it stated that if I configured two static Etherchannel ports on both switches with the CLI command "mode on" , the link will be established but without an aggregation protocol. Now my question is: is data going to be transferred in both directions if no aggregation protocol is configured?
AbdElRahman ElSherbiny Yes, it will! The end effect of the three methods: PAgP, LACP, or ‘on’ mode is the same, the etherchannel will function the same.
In regards to the EtherChannel flow calculations, I am assuming the more input data you provide the protocol with the more efficient its switching decision will be? This must come with more CPU overhead of course. However, is there usually an agreed upon method that applies generally to networks? Or is the decision done on a case by case basis depending on the network design/architecture? Say for example would the sweet spot generally be for most networks to not include too much input data(SMAC + DMAC, SIP + DIP, combinations of both etc) but also not leave it so scarce to the point where the protocol makes a less efficient switching decision than it could have if it was provided with additional input data? In short, is there a specific combination of load balancing options which apply generally that A) Make sure the switching decision process is as efficient as possible for most networks B) Not use too much processing power and C) Make sure you are not getting diminishing returns in terms of efficiency(The balance between CPU overhead and load balancing between the logical links). May be a tough one to answer and I may be off the mark here or missing some information but I couldn't stop thinking about it while watching this video haha. But it would be great if you could answer it or possibly provide me with some resources to follow up on. Thanks.
I don't know exactly how the calculations are made, you might want to try a google for things like 'etherchannel load balancing' or 'etherchannel load balancing algorithm'.
@@eternalblue4660 Check this video. It has an amazing explanation of how EtherChannel does the load balancing (algorithm) ruclips.net/video/ndQQkAKi1ag/видео.html
@JeremysITLab Amazing Video as always, but here's a question: Since There are 62 Videos each one is 30 to 40 minutes, how do you keep all that information in your brain, without forgetting what you did in the previous days, especially the configuration commands
Oh i really hate all the different commands that etherchannel has i'll have to practice this topic a lot... Anyway, thank you very much for your lectures videos Jeremy they're very usefull, you make it easier to understand, thanks :))
Hey Jeremy I have two questions. 1) Some people say it's better first to shutdown the interfaces and then configure the EtherChannel to avoid any possible misconfigurations with the other switch. Do you agree? It is recommended to do it like this or it's totally fine if I don't shut them down? 2) Can you explain please what is bandwidth, throughput and speed. How are differentiate one from another?
Hi Stefanos, 1) Shutting them down does no harm, so go for it! I personally haven't run into problems by not shutting them down, though. Whichever you prefer! 2) Often they're used interchangeably (I probably do so at various points in the course), but try a google search like 'speed bandwidth throughput' and you'll find some explanations better than I can give here! Here's a quick video too: ruclips.net/video/TVpg7StOxgg/видео.html
Jeremy! Is there a video or a list of all of the pertinent commands that are needed for the ccna? I’m sure there’s over 100 or so, I just didn’t know if I could find a list to study!?
First I would like to thank you for your lecture. Q1. can we configure LACP & PAgP on different Etherchannel? if yes, how would the load balancing mode we use?
Thanks so much ! You are easy to understand and very through! I was wondering do youhave a matching chapter list with the Odom book? I am trying to use your channel and the book to study for the CCNA test....its a bit tough to find the exact chapters so I can keep my notes together. Thanks!
At 4:54 why all lights are in green color towards DSW1 side. This is also a switch, therefore only one green light should be there and all other three in orange color as per the STP
There is smthng I've seen. I think when you use the command 'channel-protocol ?' and you choose the protocol you prefer, (ie; LACP or PAgP); the options should be minimised when you issue 'channel-group 1 mode ?'.
thank you sir for your resource and hard working. sir need a suggestion from you. I am learning python with ccna , after that i want to learn linux .please suggest me is it good decision. if not what should i learn?what should my learning path
Hi, Im following your videos for my studies and it immensely helpful for me. Im now 44 years old. Please let me know whether age become a barrier to pursue this as i have a discontinued carrier in networking job. Thank you...
Thank you for watching my videos! 44 is not too old, I have read many experiences of people who have changed careers into networking/IT in their 40s and 50s. Good luck!
Great thanks to you Jeremy. I have a question: If we configure EtherChannel statically with mode "On" being a connection between 2 switches , this means that the switchport mode trunk must have been configured previously?
Great video as usual. It would be good to see some more on troubleshooting Etherchannel. Such as how to fix this error: %EC-5-CANNOT_BUNDLE2: F0/21 is not compatible with Po1 and will be suspended (vlan mask is different). It is not making sense because all the trunks and port channel were configured to allow the same VLANs.
@@JeremysITLab Thanks. Your videos make a lot of sense, explaining things better than my instructor. I finally got my EtherChannel to work today. I had to default the interface back to their original state and recreated everything and it came up OK. But troubleshooting would be great.
Hi Jermey, I have a question.. In what sequence do you post your videos? Do you follow the exam topic list? please let me know so I can follow your pattern as I'm preparing myself for CCNA exam. Thank you so much for your great effort in helping us understanding CCNA topics
Hey Jeremy! Dump question here, so if layer 3 LAGs are a good option to avoid broadcast traffic loops etc, then why would we even consider using layer 2 ether channels? Besides, isn’t broadcast traffic necessary at all on a layer 3 LAG? What about ARP o any other broadcast 😅so how Vlans travel from access switches using Layer 2 etherchannel through agregation switches using layer 3 ether channels where broadcast traffic is not allowed ?
Hi, do you have any idea about why the Layer3 Etherchannel is not pinging each other in EVE-NG ? ports are up and in use status, everything looks good but switches are not pinging each other. Thanks
In fact using ether channel does not give actual summarize of all bandwidthes of interfaces. Real bandwidth of the session will have speed of member interfaces. E.g. if you have 6 fa ints gathered in po1, then max speed of a tcp session won't be more than 100mbps. This is what i haven't heard both in this lecture and further in lab.
5:22 we could have made vlans including some ports between the two switches using access ports right? That would just balance the load in between. Is it wrong?

At 4:54 why all lights are in green color towards DSW1 side. This is also a switch, therefore only one green light should be there and all other three in orange color as per the STP
DSW1's interfaces are all designated ports, ASW1's orange ports are non-designated ports.
absolutely superb explanation
There is smthng I've seen. I think when you use the command 'channel-protocol ?' and you choose the protocol you prefer, (ie; LACP or PAgP); the options should be minimised when you issue 'channel-group 1 mode ?'.
thank you sir for your resource and hard working. sir need a suggestion from you. I am learning python with ccna , after that i want to learn linux .please suggest me is it good decision. if not what should i learn?what should my learning path
Python and Linux are very useful skills, in all areas of IT! I think your path is a good one :)
Hi, Im following your videos for my studies and it immensely helpful for me. Im now 44 years old. Please let me know whether age become a barrier to pursue this as i have a discontinued carrier in networking job. Thank you...
Thank you for watching my videos! 44 is not too old, I have read many experiences of people who have changed careers into networking/IT in their 40s and 50s. Good luck!
Great thanks to you Jeremy. I have a question: If we configure EtherChannel statically with mode "On" being a connection between 2 switches , this means that the switchport mode trunk must have been configured previously?
It doesn't have to be, you can make an EtherChannel with access ports.
Great video as usual. It would be good to see some more on troubleshooting Etherchannel. Such as how to fix this error: %EC-5-CANNOT_BUNDLE2: F0/21 is not compatible with Po1 and will be suspended (vlan mask is different). It is not making sense because all the trunks and port channel were configured to allow the same VLANs.
Sure, I'll make some troubleshooting labs after I finish the CCNA course.
@@JeremysITLab Thanks. Your videos make a lot of sense, explaining things better than my instructor. I finally got my EtherChannel to work today. I had to default the interface back to their original state and recreated everything and it came up OK. But troubleshooting would be great.
@@JeremysITLab This idea still up ?
Thanks jeremy!
Hi Jermey, I have a question.. In what sequence do you post your videos? Do you follow the exam topic list? please let me know so I can follow your pattern as I'm preparing myself for CCNA exam. Thank you so much for your great effort in helping us understanding CCNA topics
I'm following the exam topics list, but I cover them in the order I think is best.
@@JeremysITLab Thank you for your reply!
Thanks
Hey Jeremy! Dump question here, so if layer 3 LAGs are a good option to avoid broadcast traffic loops etc, then why would we even consider using layer 2 ether channels? Besides, isn’t broadcast traffic necessary at all on a layer 3 LAG? What about ARP o any other broadcast 😅so how Vlans travel from access switches using Layer 2 etherchannel through agregation switches using layer 3 ether channels where broadcast traffic is not allowed ?
At 24:47, we're talking about the interface on the local switch correct? They must all have the same details (speed duplex etc)
Hi Jeremy,
When do you plan to start to the new 301 topics?
We are awaiting your valuable contents.
Hi! I think the new topics will be at the end of the course, there are still more fundamentals to cover (TCP/UDP, DHCP, DNS, IPv6, etc).
Hi, do you have any idea about why the Layer3 Etherchannel is not pinging each other in EVE-NG ? ports are up and in use status, everything looks good but switches are not pinging each other. Thanks
Hello Jeremy, do we do load balancing when we use layer 3 switches?
Hi!!!! 🤠
Thamk You!
Thanks for watching!
In fact using ether channel does not give actual summarize of all bandwidthes of interfaces. Real bandwidth of the session will have speed of member interfaces. E.g. if you have 6 fa ints gathered in po1, then max speed of a tcp session won't be more than 100mbps. This is what i haven't heard both in this lecture and further in lab.
10:12 “Frames in the same flow will be forwarded using the same physical interface”
@@JeremysITLab You are right. But i'd underline this with more attention.
@@JeremysITLab please, understand that I don't want to stupidly criticize your great and heavy work. I just want it to be ideal. :)
Thanks Jeremy
Thanks for the comment Neil, hope the video is helpful.
5:22 we could have made vlans including some ports between the two switches using access ports right? That would just balance the load in between. Is it wrong?
