MicroNugget: Spanning Tree Protocol Explained | CBT Nuggets

In this video, CBT Nuggets trainer Jeremy Cioara explains how to configure spanning tree protocol as well as the different types of spanning tree protocols. Buckle up for this fast-paced, advanced exploration of spanning tree configuration modes and settings.

Spanning tree is highly conceptual. You could spend a lot of time learning about: what's the root bridge; how it's elected; how other switches find the best way to the root bridge and block redundant paths; what happens if the root bridge fails; how root bridges failover and how much time it'd take; and much more.

But when it comes to configuring STP, there’s one command that matters: electing the root bridge. Whether you’re studying for spanning tree, thinking about it, or implementing it, that’s the command to be aware of.

Port Priority, Port Cost, and Hello Time have their uses as well, but they’ll be special use and rare. Learn about the command you need to elect the root bridge and your spanning tree protocol configurations ready to go in no time.

Follow along with Jeremy as he digs deep into a spanning tree topology and configures it for you so you can get a deep, hands-on understanding of STP.

[sedamean]

Do we need to apply command for all SW?

[FilsSteven]

When I change the cost of an interface in spanning-tree why is it seemingly unnecessary to change the cost of the int at the other end of the link?

[tedtdu]

spanning-tree cost  ..? no such command
