`spanning-tree mode`

Syntax

spanning-tree mode {mstp|rpvst}

Description

Sets the spanning tree mode that the switch runs as either MSTP mode (Multiple-instance Spanning Tree Protocol) or RPVST mode (Rapid Per VLAN Spanning Tree). If you want to change the spanning tree mode, you have to disable spanning tree first (use the no spanning-tree command) and then you can change the mode.
