78 Configuring & Monitoring the Switch VH-2402S2
Configuring Spanning Tree Parameters
The VH-2402S2 switch supports the IEEE 802.1D Spanning Tree
Protocol. This protocol allows redundant connections to be created
between LAN segments for purposes of fault tolerance. Two or more
physical paths between different segments can be created through the
switch, with the Spanning Tree Protocol choosing a single path at any
given time and disabling all others.
If the chosen path fails for any reason, a disabled alternative is activated,
thereby maintaining the connection. See Appendix A, “Spanning Tree
Concepts” on page 91 for further information on using the Spanning Tree
Protocol in a network.
To configure Spanning Tree Parameters, do the following:
1. Select the Device Control Menu from the Main Menu.
2. Select the Spanning Tree Configuration Menu and then STA Bridge
Configuration.
3. Turn the switch Spanning Tree operation on or off by setting the
Spanning Tree Protocol field to ENABLED/DISABLED.
4. Form the Spanning Tree Configuration Menu, select STA Port
Configuration.
The Spanning Tree Port Configuration Menu displays. Change the
parameters that display in this menu as required.
Configuring Spanning Tree parameters from their default
can cause serious deterioration of network performance.
