i livestreamed a lab earlier today demonstrating the difference between a hub & a switch. will make prettier videos out of this setup later but wanted to experiment with it on live for fun 🤗 here ya go

did you notice how the hub reacts when you flip it upside down? make sure you put something under it to catch the packets that get dropped.

LOL!

back when hubs were all the rage, but prior to the ubiquity of switches, it was possible to discern the logic that was evolving in hubs, in particular regarding how they managed collision storms Man that shit was so interesting, said the old man. It heartens me to see you at it

Ah I miss hubs and being able to see everything everyone is doing

What happens if you have the hub plugged into a port on the switch. Does the switch learn all of the MAC addresses on the hub, and forwards packets to all of those MAC addresses to the port the hub is on, and then the hub transmits all of them out every port?

Excellent video. Not done stuff like that for years but it’s how people should teach/learn, ground up understanding. Serves you well in the long run.

Network engineering is bae. Network engineering is life. FWIW, I find unedited videos sometimes more educational. Too many people edit out moving cables, applying config, troubleshooting etc.. Seeing those things happen “live” is a great way to learn. Nice vid 😊

thanks for the feedback!! i will probably do some more live labs in the near future

COLLISIONS ARE RED, captain! I repeat: COLLISIONS RED!

Thank you for all the crap you deal with to share quality information. You are appreciated.
