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.
The chapter describes the following commands:
• show spanning-tree on page 310
• show spanning-tree interface on page 311
• show spanning-tree mst detailed on page 312
• show spanning-tree mst port detailed on page 313
• show spanning-tree mst port summary on page 314
• show spanning-tree mst summary on page 314
• show spanning-tree summary on page 315
• show spanning-tree vlan on page 315

Note: The SFTOS 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. 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.
