26.6.2 Configuring Single Spanning Tree
- Points to note
-
The example below shows how to start or stop Single Spanning Tree. Single Spanning Tree does not run simply by setting the pvst or rapid-pvst operation mode, but start operation according to settings.
VLAN 1 (default VLAN) and Single Spanning Tree cannot be used at the same time. When Single Spanning Tree is set, the VLAN 1 PVST+ stops.
Command examples
-
(config)# spanning-tree single
Runs Single Spanning Tree. This setting stops the VLAN 1 PVST+, making VLAN 1 a Single Spanning Tree target.
-
(config)# no spanning-tree single
Stops Single Spanning Tree. When a VLAN 1 PVST+ is not set to stop, and 250 PVST+ instances are not already running, VLAN 1 PVST+ operation starts automatically.
