MSTP Configuration Guidelines
This section provides important information about configuring Multiple Spanning Tree Groups:
When MSTP is turned on, the switch automatically moves all VLANs to the CIST. When
MSTP is turned off, the switch moves all VLANs from the CIST to STG 1.
When you enable MSTP, you must configure the Region Name. A default version number of 1
is configured automatically.
Each bridge in the region must have the same name, version number, and VLAN mapping.
MSTP Configuration Example 1
This section provides steps to configure MSTP on the G8124.
1. Configure port and VLAN membership on the switch.
2. Set the mode to Multiple Spanning Tree, and configure MSTP region parameters.
3. Assign VLANs to Spanning Tree Groups.
