Configuring Spanning Tree Parameters

The VH-2402S 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 85 for further information on using the Spanning Tree Protocol in a network.

Configuring Spanning Tree parameters from their default can cause serious deterioration of network performance.

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.
