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.
Thank you, for the time and effort you put in this video. To compare simulation with a real world environement makes it so much easier to understand, and it was really fun to see the broadcaststorm happening before our eyes, it was impressive.
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
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!
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 UA-cam channel I have understood how switch and routers communicate especially how layer 2 switch and layer 3 switches communicate Thanks 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!!!
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 UA-cam? 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 UA-cam 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!

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
Great demo for BPDU filtering and loop guard. It help me visualize real-time and appreciate your effort!
❤🎉 Thanks a lot, David! It's very considerate of you having some time set aside to help us improve our net skills. 😊
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
thank you this is one of the best illustration of you everything works a real network....
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.
Always to the point and clear 💯
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!
Heck yeah! This is the kind of training I’ve been looking for!! 🎉
Hey they Sir Dav I'm delighted to be here yet agian for another amazing journey with you
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.
Thank you for the great sharing again my best teacher of networking engineering of all time 🎉❤
Many thanks for the real-life demonstration of STP attacks.😁
Even since I subscribed to your UA-cam channel I have understood how switch and routers communicate especially how layer 2 switch and layer 3 switches communicate
Thanks David
Thank you, David.
Excellent explaination with practical.
Awesome network demonstration! Thanks a lot, appreciate your efforts!
Glad you liked it!
I'm a great fan and I great lover of your work thanks Alot for always advising, teaching, and educating us thanks
Waouw top video I'm learning how spanning-tree really works. THX from Belgium!!
Thank you! You are very welcome!
Thanks for being on UA-cam
This is a pretty cool video. Ngl!
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 🙂
Thanks for the cool videos! @2:18 You mean BPDU filter
You are my favourite youtuber 🐧
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 David
Thank you
awesome sir!
God bless you 😇
Thank you!
How funny, I just watched a Wendell Odom video the other day about bpdu filtering, and he used the exact same topology.
Much better
Wow!
Edit: What other method to stop this command?...🤔
merci

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 UA-cam?
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 UA-cam 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?
can you share the PDFs for the course
how you control all computers on one screen?
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.
Hey Dave please can you please answer me please
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 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...
