set spantree version
6-8 Spanning Tree Configuration
Mode
Switch command, read‐only.
Example
This example shows how to display Spanning Tree version information for the device:
D2(su)->show spantree version
Force Version is mstp
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.
Syntax
set spantree version {mstp | stpcompatible | rstp}
Parameters
Defaults
None.
Mode
Switch command, read‐write.
Usage
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.
Example
This example shows how to globally change the Spanning Tree version from the default of MSTP
to RSTP:
D2(su)->set spantree version rstp
clear spantree version
Use this command to reset the Spanning Tree version to MSTP mode.
Syntax
clear spantree version
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.
