4 USING RESILIENCE FEATURES Spanning Tree Protocol (STP) Setting up resilience on your network helps protect critical links against failure, protects against network loops, and reduces network downtime to a minimum. This chapter explains the features supported by the Switch that provide resilience for your network. It covers the following topics: ■ Spanning Tree Protocol (STP) ■ Rapid Spanning Tree Protocol (RSTP) - an enhanced version of the STP feature. For detailed descriptions of the web interface operations and the command line interface (CLI) commands that you require to manage the Switch please refer to the Management Interface Reference Guide supplied in HTML format on the CD-ROM that accompanies your Switch. The Spanning Tree Protocol (STP) makes your network more resilient to link failure and also provides a protection from loops - one of the major causes of broadcast storms. STP is enabled by default on your Switch. To be fully effective, STP must be enabled on all Switches in your network. RSTP provides the same functionality as STP. For details on how the two systems differ, see "How RSTP Differs to STP" on page 45. The following sections explain more about STP and the protocol features supported by your Switch. They cover the following topics: ■ What is STP? ■ How STP Works ■ Using STP on a Network with Multiple VLANs

—
an enhanced version of the
STP feature.

Spanning Tree
Protocol (STP)
The Spanning Tree Protocol (STP) makes your network more resilient to
link failure and also provides a protection from loops — one of the major
causes of broadcast storms. STP is enabled by default on your Switch.
To be fully effective, STP must be enabled on all Switches in your
network.
RSTP provides the same functionality as STP. For details on how the two
systems differ, see
