PVST+ Per-VLAN Spanning Tree Protocol - Part 1

A tutorial on Per-VLAN Spanning Tree Protocol (PVST+) for the Cisco CCNA using Packet Tracer. In Part 1, I explain some of the basics about PVST, PVST+ and their similarities and differences to STP. I configure the switches to utilize PVST+ features within a multi VLAN network.

Cisco should pay you and put your videos up with the rest of the cisco academy tools. you're brilliant! you keep it very simple thanks!

You are a lifesaver man, I'm following IT on college and this helped me with everything we've seen so far in class, much better explained than my teacher could ever do! Thank you very much!

[@salamshammas5938]

that was very helpful, great explanation and easy to understand.
I actually did this network the way you did it, and worked great for me from the first try :)
THANK YOU SO MUCH

Thanks.. I like it

The reason the root bridge shows altn (blocking) interfaces is because of pvst convergence time. It takes a switch about 30 seconds to go from a blocking state to a fowarding state

get a 403 forbidden error when i try to access your website?

Hi Dan- In S1, we see that the "show spanning tree" option showed us the two VLANs as the root bridges. However, these VLANs showed their ports as both FORWARDING and BLOCKING. A root bridge should have both FORWARDING PORTS right? I would really appreciate if you explain this.

[@TheAnkurj]

Also, from the "show spanning-tree output", how do we determine which VLAN is the primary/ secondary. Kindly let me know.

[@TheAnkurj]

Ankur Hazarika I am kind of confused here as for the switch S1's output from your video, both the VLANs- 1 and 5 shows up as Root bridges, man.

[@naveenrajkali1790]

At 8:46 why do your ports say they are in blocking mode? all port of root bridge supposed to be in fwd state

[@reggiejax]

At 8:46 why do your ports say they are in blocking mode? I thought the root bridge wasn't supposed to have any blocked ports. When I did the same thing you did all of my ports were in forwarding mode,

[@naveenrajkali1790]

I too av same doubt....Any ans for this

[@sarthakgupta1822]

At 9:41 my interface g1,3 both are still desg. why hasn't it changed ??
i have followed the cli commands carefully.

[@ibrahimahmed1996]

creating a vlan did not update the spanning-tree list. i checked by using show spanning-tree

[@emixiak]

Why not use rapid pvst?

[@CJDavislife]

The starter link is broken :(

[@Illum1ne]

what kind of switch he used?

[@alaakhalifa6853]

2960

[@serpasha]

In Packet Tracer 2960 does not have more than 2 ports (Gig) are you sure? And can not be customized.

[@sakthiprakash7443]

Hi sir plz send another link bcz it doesn't work
