What is a SWITCH? // FREE CCNA // Day 1

Brilliant teaching mate, studied A+ and Net + many years ago for my MCP but never got a job in IT , I have always been a computer geek and am so interested in the CCNA stuff just feel at 55 yrs oldie may be too late for me now .....but I'm still trying to learn now thanks to you. Thank you 👍

I absolutely love your videos. You are very good at keeping people’s attention. I especially liked “you suck at subnetting”.

I’m hoping you can answer a question that might be easy for you…

I have a switch configured by someone that didn’t necessarily know how to do it and it was one dedicated to my CCTV network.

I configured the cameras and the NVRs. A guy connected them to a switch he configured.

When I am on any computer on the main network (different IP completely), I can’t see my cameras. My cameras are on a different network.

How do I tell the switch to allow the main network to access my cctv network? I can only access mine from the cctv switch when I change my computers IP to the camera network.

Any help you provide would be greatly appreciated. Thank you!!!!

Is this course still going on?

Thank you for your tutorial

Gosh, you just seem like such a nice, kind and enthusiastic man. It's a joy learning from you Chuck!

As soon as I have connected the Wireless device to the switch it shows an amber light so I can't ping it can anyone please help me to understand what I have missed over here?

Hey Chuck the link for the lab isn't working

I passed all the quiz qns😊

Absolutely amazing can’t believe I’m paying thousands for college when you do such a better job!!! Thank you so much

awesome content

saying amazing and cool 20 times a minute is a bit much for me 🤢🤮

The visual effects and the teaching method is absolutely brilliant. This man gives so much motivation to learn and keep going. I am on maternity leave returning to office (service provider) in a year and wanted to refresh my knowledge. Never seen such an enthusiatic teacher with so well prepared material. Thanks so much, it actually gives big motivation to go for the exam 👏👏.

the link for the packet isnt working

This is great!!! Networking has been a weakness. When you explain things I can actually visualize what is happening. Tysm!!

So are hubs an older version of a switch????

Do none of these is wireless, this is for like wire connected computers in an office or something??

which web browser do u use?

So I’m actually just starting doing the Cisco netacad and this video is so much more helpful then the site thank you Chuck!!

oh hi mark

your lab link is not opening

First of all, thank you so much for the good explanation.
Can you make a video to explain what is difference between Multilary Switch and Layer3 Switch?

I actually have hope that I can learn and one day pass the CCNA exam.

Just amazing....I was sick of dry videos. I'll definitely watch the whole course, thankyou very much.

The Room, Harry Potter... I see you're a man of culture 🤣

Do you any ccna study notes, summaries that could help prior to the exam in a few day or on the day of the exam? I hope you wont let me down, ibam running out of time and my work demands i get certified ccna

Best networking tutor online or offline! Pretty much the sole reason I started my IT journey. Thank you Chuck!

Thank You!

the way you explain, the way you smoothly bring up a joke everything bro you deserve great gratitude

Bro pets the switch

This video is phenomenal! Amazing job! I love how excited you are about the subject! I was trying to learn about this for a while. This is the best video/anything I found explaining the subject!

Hi, does anyone know how to "Break or Exit in the IOS command line" in MacOS" using Packet Tracer? I've tried (Ctrl + C, Ctrl + Shift + C, Cmd + C) nothing works.
I also haven't seen the setting to see the keyboard shortcut mappings and how change a certain shortcut. This is making me go insane. Can anyone please help? Thank you.

iloveitbro

You are My Inspiration and RoleModel 💕💕💕💕💕💕💕💕💕💕😍😍

I don't get one thing that he just fully skipped in the video

At first the switch doesn't know which port Computer A or B live on, so when Computer A sends a packet to computer B, the switch knows and learns from the source address which port Computer A is on (as he explained), but still has no idea where Computer B is. I have read that it then does "flooding" where it just simulates a hub by just sending the received packet to all remaining ports because the right one has to be among them. I mean at some point Computer B will have to send a packet over the network but if it didn't?

But in Cisco Packet Tracer I don't see that simulated? Or is there just an in-between step that was already performed at the beginning, before we went into simulation mode?

So all traffic from laptops connected to the wifi network at an office are being broadcasted out to all other wireless devices connected to that particular WAP? All the of the management at my company uses wireless laptops, this seems like a potential issue?

i though the switch send its message to all ports and then the recieving will acknowledge the message by sending that i had recived the message from the sender..
