Spanning Tree (STP) Commands

This chapter provides a detailed explanation of the Spanning Tree commands. The commands are divided into two functional groups:

•Show commands display switch settings, statistics, and other information.

•Configuration commands configure features and options of the switch. For every configuration command, there is a show command that displays the configuration setting.

Note: The software platform STP default mode is IEEE 802.1s, but the legacy IEEE 802.1D mode is available. To change to the legacy IEEE 802.1D mode, set the STP operational mode to disabled, then enable the IEEE 802.1D mode from the source code. Recompile the software to operationally enable the IEEE 802.1D mode. With the IEEE 802.1D mode operationally enabled, the rapid configuration and multiple instances features are not available. If the rapid configuration and multiple instances capabilities are required, use the IEEE 802.1s mode which is compatible with the legacy IEEE 802.1D standard.
