CN4093 Application Guide for N/OS 8.4
This section provides important information about configuring Multiple Spanning
Tree Groups:
When MSTP is turned on, the switch automatically moves management VLAN

4095 to the CIST. When MSTP is turned off, the switch moves VLAN 4095 from
the CIST to Spanning Tree Group 128.
 When you enable MSTP, you must configure the Region Name. A default
version number of 0 is configured automatically.
Each bridge in the region must have the same name, version number and VLAN

mapping.
This section provides steps to configure MSTP on the CN4093.
