Sir, I enjoyed your videos and this is tremendous work. Needs little improvement: 1 - please give appropriate title to the video so we can understand the topic. 2 - please give a “number” to the video title, it will help us to keep up with the course without missing a video. If we missed any video, so we can track the missed one by its number. Thanks
This is so helpful. You have really hit on something beneficial here by using real hardware and focused topics such as this. Excellent work on the video, and thank you very much for sharing your knowledge.
lol we did this in my CLSC class back in 2000 when they shipped cat 5000s to the class. The instructor said if you introduce a loop in the network you can run the cpu to 100%, I was like really? cool, lets do it.. and we proceeded to. It was an awesome practical demonstration.
Even since I subscribed to your RUclips channel I have understood how switch and routers communicate especially how layer 2 switch and layer 3 switches communicate Thanks David
Thank you David for showing how a broadcast storm can really paralyse a switched Ethernet. I have seen it happen as you demonstrated and it does not take long. Good demonstration!
Great Work but i've problem to understanding maybe b'coz i don't have pre-knowledge of networking but you've done great demonstration and explanation!!!
Is it recommended to get David's course on Udemy for CCNA 200-301 or should I wait for him to release his course on RUclips? David, does your course cover v1.1 on Udemy with a similar teaching technique to this? I agree, I learn much better by seeing real life scenarios and not following presentation slides. Thanks!
My dream is to become a cyber security professional but I don't have any money to buy course online so I will please like to ask you can you give me a series of RUclips video both on your channel and any other where I can learn everything I need to know about ethical hacking and cyber security from a beginner aspect to mastery please where I can learn about the theory and the practical concept please Dav please that's my worry
Great video, but I don’t understand why the CCNA content started off strong and then quickly jumped into advanced topics. Most creators usually begin with basics like networking devices, then move on to IP addressing and gradually progress to intermediate topics before tackling the advanced material. I was really enjoying it at first, but I got lost once it shifted to more advanced concepts too soon.
But please I have a problem please I need your help I'm a Third year student at university studying Computer Engineering but our school doesn't teach us what I need
sir i think your doing joking , I waiting for you after 12 days because you uploaded a video in which talked about this free course but I can not see any video related CCNA ... so kindly plz stop fake video promise

Thank you! You're welcome!
thank you this is one of the best illustration of you everything works a real network....
it's always pleasure to take networking lessons with david it remind me my first step as student and I hope to all of you much success
You do a great job but If you can make videos every week it will be good i appreciate what you do for us 😊
We've had some technical issues... but hopefully a lot more content coming soon 😀
Thank you, really expecting more content.
❤🎉 Thanks a lot, David! It's very considerate of you having some time set aside to help us improve our net skills. 😊
Awesome network demonstration! Thanks a lot, appreciate your efforts!
Glad you liked it!
Many thanks for the real-life demonstration of STP attacks.😁
Excellent explaination with practical.
Thank you for the great sharing again my best teacher of networking engineering of all time 🎉❤

Heck yeah! This is the kind of training I’ve been looking for!! 🎉

Good demonstration!
Waouw top video I'm learning how spanning-tree really works. THX from Belgium!!
Thank you! You are very welcome!

Thank you, David.
Great Work but i've problem to understanding maybe b'coz i don't have pre-knowledge of networking but you've done great demonstration and explanation!!!
Thanks for the cool videos! @2:18 You mean BPDU filter
Thanks for being on RUclips
How funny, I just watched a Wendell Odom video the other day about bpdu filtering, and he used the exact same topology.
I was Waiting and finally i got the first step
Hi Dave - small typo at 4:57 "loop gaurd" - please leave it there to remind everyone that you are human 🙂
You are my favourite youtuber 🐧
Thanks David
This is a pretty cool video. Ngl!
Thank you
awesome sir!
Is it recommended to get David's course on Udemy for CCNA 200-301 or should I wait for him to release his course on RUclips?
David, does your course cover v1.1 on Udemy with a similar teaching technique to this?
I agree, I learn much better by seeing real life scenarios and not following presentation slides.
Thanks!
Wow!
Edit: What other method to stop this command?...🤔
Please teach all Kali Linux programs
Please
merci
Much better
My dream is to become a cyber security professional but I don't have any money to buy course online so I will please like to ask you can you give me a series of RUclips video both on your channel and any other where I can learn everything I need to know about ethical hacking and cyber security from a beginner aspect to mastery please where I can learn about the theory and the practical concept please Dav please that's my worry
Do you recommend setting loop guard global on all switches then?
how you control all computers on one screen?
can you share the PDFs for the course
Wait what? How does a port stay UP when it is receiving no light? Once down, it ain't sending anything.
Great video, but I don’t understand why the CCNA content started off strong and then quickly jumped into advanced topics. Most creators usually begin with basics like networking devices, then move on to IP addressing and gradually progress to intermediate topics before tackling the advanced material. I was really enjoying it at first, but I got lost once it shifted to more advanced concepts too soon.
But please I have a problem please I need your help I'm a Third year student at university studying Computer Engineering but our school doesn't teach us what I need
Hey Dave please can you please answer me please
😊
Sir I emailed you, but didn't get any reply, it's something urgent sir
sir i think your doing joking , I waiting for you after 12 days because you uploaded a video in which talked about this free course but I can not see any video related CCNA ... so kindly plz stop fake video promise
Stop being a clown and be appreciative. He’s not compelled to do what’s he’s doing.
@@DearGod-e2f did you know one months gone but but still there is no video of CCNA ...I am waiting for weeks for course...what I do...
