MSTP Configuration Guidelines
When Multiple Spanning Tree Protocol is turned on, the following applies:
The switch automatically moves all VLANs from STP Group 1 to the Common Internal
Spanning Tree (CIST).
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.
Region Name must be configured. By default, the revision level is set to 1. Each bridge in the
region must have the same name and revision level.
Each bridge in the region must have the same VLAN and STP Group mapping.
MSTP Configuration Example
This section provides steps to configure Multiple Spanning Tree Protocol on the HP GbE2c

VLANs on Example Switch 1” on page 97.
2. Set the mode to Multiple Spanning Tree, and configure MSTP region parameters.
