Configuring the WSM using Device Manager

About Spanning Tree protocol

To prevent loops in the network topology, the WSM supports IEEE 802.1d Spanning Tree Protocol (STP) with 16 configurable spanning tree groups (STGs). STG 1 is the default STG for all VLANs. You can assign individual VLANs to any of the other 15 STGs.
