30.1.2 Flow of Ring Protocol settings

(1) Stopping spanning tree

When the Ring Protocol is used, we recommend that you stop Spanning Tree Protocols in advance. However, note that when the Ring Protocol and a Spanning Tree Protocol are used together with the Switch, there is no need to stop the Spanning Tree Protocol. For details about stopping Spanning Tree Protocols, see 28 Spanning Tree Protocols.
