5.2.1.4 set spantree version
Use this command to set the version of the Spanning Tree protocol to MSTP (Multiple Spanning
Tree Protocol), RSTP (Rapid Spanning Tree Protocol) or to STP 802.1D-compatible.
set spantree version {mstp | stpcompatible | rstp}
Syntax Description
Command Defaults
None.
Command Mode
Read-Write.
Example
This example shows how to globally change the Spanning Tree version from the default of MSTP
to RSTP:
NOTE: In most networks, Spanning Tree version should not be changed from its default setting of
mstp (Multiple Spanning Tree Protocol) mode. MSTP mode is fully compatible and interoperable
with legacy STP 802.1D and Rapid Spanning Tree (RSTP) bridges. Setting the version to
stpcompatible mode will cause the bridge to transmit only 802.1D BPDUs, and will prevent
non-edge ports from rapidly transitioning to forwarding state.
mstp Sets the version to STP 802.1s-compatible.
stpcompatible Sets the version to STP 802.1D-compatible.
rstp Sets the version to 802.1w-compatible.
