Configuring Spanning Tree Settings for Switch Ports

Purpose of 
Spanning Tree

STP prevents loops in layer 2 networks that have redundant paths. Loops in 
layer 2 networks can result in duplicate frames and switches learning the 
same MAC addresses on multiple interfaces. 

To prevent loops, STP calculates a single path through the network and then 
blocks any redundant paths. STP first identifies a root switch and then 
identifies the most efficient path from the root switch to each switch in the 
network. Any redundant paths that exist enter a blocked state. 

If a network segment in the spanning tree becomes unreachable or if you 
change the cost of a path, Spanning Tree recalculates a path through the 
network and then activates the new best path. 

RSTP vs. STP

In software version 6.0, the 802.1D Spanning Tree Protocol (STP) is 
replaced with the Rapid Spanning Tree Protocol (RSTP). STP is relatively 
slow at recovering from a failure in the network. RSTP was created to 
decrease this recovery time. 

When a switch is running RSTP, a port can change from blocking to 
forwarding more quickly than when the switch is running STP. This 
decrease in transition time makes it possible for RSTP to recover more 
quickly from failures in the network.
