one of the best ever video tutorial on STP...I learned a lot about this topic. Thank you for using diagrams and
and Switches to make things way easier to understand for viewers like me.

Hi Keith. Do you know of an easy way to reconstruct the switch topology without using CDP or LLDP? Assuming of course that the interface descriptions are also not trustworthy.

I think the best way would be using STP output. But I imagine this gets very tricky if only one switch (SW1) connects to the root bridge, while all other switches (e.g. SW2, SW3) reach the root via SW1, by being plugged into SW1 directly. Using only the show spanning tree outputs, I don't see how we could check which interfaces of SW1 switches SW2, SW3 connect to. Although, we could look at SW1's ARP table for that information.

Even worse: what if there are additional switches (e.g. SW4, SW5) which reach SW1 via SW2, SW3?

Could you perhaps do a demonstration on how to map a network like that? I know it's a bit of a fringe topic, but I'm sure it would be interesting to see.

Thank you.

I removed the two connections between the SW1 and SW2 and it worked well!! Why was that two connections necessary? Thank u so much! Your videos really helped me. May God Bless you!

If four switches are part of STP in a segment. How many switches will have blocking ports?

I'm studying Cyber in Australia, and we are studying Cisco packet tracer. If it wasn't for Keith Barker I would not have passed the first Semester. And now I'm doing Semester 2, it's Keith Barker to the rescue again.
Thank Keith. So informative and easy to watch. I'm grateful to you (and have recommended this channel to all the students and the lecturers as well!)

Hey @Keith
sw 2 port 1/3
what does 1/3 stand for?
from my experience, i thought 1 is the stack in the switch is in and 3 would be the port but what confused me has that on sw2 there is 3/0 and 3/3. Could you explain.

Next step is the road to CCNP :)
