Displaying Spanning Tree Information for VSDs

Use the Spanning Tree by VSD window to display the currently configured VLAN Secure Domains (VSDs). Click the Details button to get more information about a VSD.

A VLAN Secure Domain is a logical set of one or more VLANs that operates with one spanning tree.  The resulting configuration is a set of distinct bridge ports isolated from other ports on the same line card by blocking all unicast and multicast traffic between the VSDs.  The GS2000 line card presently supports one VLAN per VSD, but the VSD concept provides for expanded support of multiple VLANS within a single VSD.
