Configuring Multiple Spanning Tree Groups
This configuration shows how to configure MSTP Groups on the switch, as shown
in Figure 5-3.
1. Configure port membership and define the Spanning Tree groups for VLAN 1.
Enable tagging on uplink ports that share VLANs. Port 51 and port 52 connect to the Enter-
prise Routing switches.
Add server ports 1 and 2 to VLAN 1. Add uplink ports 51 and 52 to VLAN 1.
2. Configure Multiple Spanning Tree Protocol.
Configure the MSTP region name, set the Spanning-tree mode to mst, and configure the
version.
