VLAN participation in Spanning Tree Groups

The following table shows which switch ports participate in each Spanning Tree Group. By default, server
ports (ports 1-16) do not participate in Spanning Tree, even though they are members of their respective
VLANs.

Configuring Multiple Spanning Tree Groups

This section explains how to assign each VLAN to its own Spanning Tree Group on the 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.
