BLADE OS 5.1 Application Guide
BMD00113, September 2009 Chapter 5: Spanning Tree Protocol 117
Configuring Multiple Spanning Tree Groups
This section explains how to assign each VLAN to its own Spanning Tree Group on example
switches 1 and 2.
By default, Spanning Tree Groups 2-127 are empty, and Spanning Tree Group 1 contains all
configured VLANs until individual VLANs are explicitly assigned to other Spanning Tree Groups.
Except for the default Spanning Tree Group 1, which may contain more than one VLAN, Spanning
Tree Groups 2-128 may contain only one VLAN each.
Note – Each instance of Spanning Tree Group is enabled by default.
Configuring Switch 1
1. Configure port and VLAN membership on Switch 1 as described in the “Configuring Ports and
VLANs on Example Switch 1” on page 97.
2. Add VLAN 2 to Spanning Tree Group 2.
VLAN 2 is automatically removed from spanning tree group 1.
3. Apply and save.
Configuring Switch 2
1. Configure port and VLAN membership on Switch 2 as described in the “Configuring ports and
VLANs on Example Switch 2” on page 99.
2. Add VLAN 2 to Spanning Tree Group 2.
VLAN 2 is automatically removed from spanning tree group 1.
3. Apply and save.
