Cisco Live 2012 Dream Team Application - Ryan Knebel
Cisco is picking 10 of their Netacad students to go along to their Cisco Live convention this year and help set up the network operating center. This video will accompany my application.

How Spanning Tree Protocol Prevents Loops
มุมมอง 87K12 ปีที่แล้ว
This is a sketchout of how spanning tree prevents loops. - Update/correction: In the video, when I refer to links in red as "shutdown", that is not technically correct. The links are still up, but in a blocking state as far as spanning tree is concerned. This means that those ports will still show as "connected" according to show commands even though they won't be forwarding or receiving normal...
How to convert Binary and Hexadecimal Numbers into Regular ones

This is a comparison of Binary, hexadecimal and Base-10 numbers I'm doing for my written communications class.

i know it’s kind of very late but how the switches send a reply back as i cannot see any path left to send a reply in the topology ?
Very informative. Straight to the point and instructive. Thanks for sharing.
very nice tutorial, thank you very much
Very good clarification of STP. I needed to hear and see how it works. GOT IT!
thanks, man . BTW you can easily do voice for westren movies !!!!! cool voice
I subscribed to your channel after watching your video on stp,,could you please please post lots and lots more ccna type videos,
Great explanation. Thanks
Beautifully explained. Thank you very much
quite simple and informative. Good way of representation , it helped.
Great Video, must all switches have STP?
Quite clear. Thank you ;-)
Wow this vid was posted 5 yrs ago. Anyway, when you say it's still up but in blocking state....what STP command did you use on the ports?
Great Video.. Thank you..
Good video
Thank you. This is very helpful.
So, this decides it. Gonna start studying networking. It's a fatal flaw that I don't know much so I can't offer more complex network solutions, just basic ones.
amazing explanation, i was pretty confuse about STP. thanks man
Great video
Nice video thanks for the upload. I also have to draw out the networks and how protocols work in order to get a better understanding. Well done.
Great video to describe how the loops are prevented. Books never really go over this side of things.
simple and easy to understand. Good job Sir..
great vid cheers
Ryan Knebel thanks a lot, I hope more videos from you, and you've got my respect
on what base root switch is selected??
Brigde Priority normally they're all default unless configured and then Lowest Mac-address
Srikanth gowda
It will follow als-1 to the Chicago port trunk
thank you sir
Very very good, thank you so much!!!
Excellent -Thank You !!
Thank you!!
Thank you so much for the video... this did a way better job of explaining STP and Bridge Loops than any other video I've seen.
Try RSTP. Rapid Spanning Tree- which pretty much an enhancement and a more advanced SPT.:)
Genius! The missing ingredient to most STP explanations.
great ... thannnnk
From the general perspective great explanation. Will be great to go with the emulated lab version representation of it, If I get to make the video I will credit your video and link this as well. Excellent work.
Nice
Greatly explained.
Thanks much....great video
Thanks
Awesome, This cleared up the whole concept for me. Thank you sir!
it will be more expressive, if you explain along with the port states.....
Great video man, I have a question.. how's the root elected? I've read that they have an ID and the lower gets it but I don't understand
When you connect all the switches the first time, they would all have same priority by default. The switch with the lowest MAC address would be selected as a root in that case. But should you been keen on making a specific switch as Root, you can always give it a higher priority which will override the MAC election.
+tincho from what i've read, the switch with the lowest priority number will be elected as the Root Bridge, priority number is configurable.. but if the priority is not configured yet, the switch with the lowest numerical MAC address will be the RB (Sw A MAC Addr 11:11 is lower than Sw B MAC Addr 22:33, therefore Sw A is the RB). www.dummies.com/how-to/content/spanning-tree-protocol-stp-introduction.html
the one with the lowest mac address gets elected by default if config has not been taken place bro
Thanks man - Great Video -- Nicely Put Together
Just a comment. When a port is in blocking state, it DOES accept BPDUs.. The only time it doesn't listen sis when it's disabled
Well, your video seemed to insinuate that blocking ports do not listen, which is not true--thus my repsonse Thanks
+Mike Barrett I know this is a year down the line so anyone feel free to chip in. So the switch the PC is connected to sends out the BPDUs to the other switches (via the connections that aren't redundant). Those switches receive the BPDUs and do the same, the links are up and ports aren't blocked as such but the switches just don't use the redundant connections? It makes sense in my head. I think. I couldn't understand how in example 1 als-1 and dls-2 decided who was doing the "blocking" but this makes more sense.
After many hours search about spanning tree this video made it completely clear to me. Thanks a lot for this great video.
Great video thank you :)
wow cool THNKS bro u rock (Y) :)
Hey all... I host a website ITnotes.in... Its mainly about Cisco Configurations.... I would appreciate if you guys could visit it and provide a comment...
Wild website... Looks great
Great tutorial. This helps a whole lot. Thanks!
Great job.
This was SO helpful, thank you so much for the simple and easy to understand explanation!! :)
