Switching 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 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. 

This command sets the MSTP Max Hops parameter to a new value for the common and internal 
spanning tree. The max-hops value is in a range of 1 to 127.

This command sets the Bridge Max Hops parameter for the common and internal spanning tree to
