Spanning Tree Protocol (STP)
Using the Spanning Tree Protocol (STP) functionality of the switch
makes your network more fault tolerant. The following sections
explain more about STP and the STP features supported by the
switch software.
Note
STP is a part of the 802.1D bridge specification defined by the IEEE
Computer Society. To explain STP in terms used by the 802.1D
specification, the Gigabit switch will be referred to as a bridge.
Overview of the Spanning Tree Protocol
STP is a bridge-based mechanism for providing fault tolerance on
networks. STP allows you to implement parallel paths for network
traffic, and ensure that
❑ Redundant paths are disabled when the main paths are
operational.
❑ Redundant paths are enabled if the main path fails.
