Spanning Tree Protocol Configuration
This chapter contains a complete sample Spanning Tree Protocol (STP) configuration.
Spanning Tree Protocol (STP) is a network protocol that ensures a loop-free topology for Ethernet networks. The basic function of STP is to prevent bridge loops. Spanning tree also allows a network design to include redundant links to provide automatic backup paths if an active link fails, thus, eliminating the need to manually enable or disable the backup links.
Topology
The following example is a simple multi-bridge topology.

Note: Run the switchport command on each port to change to Layer-2 mode.
