Chapter 14 Switch Configuration

14.3 Multiple/ Rapid STP Configuration

STP (Spanning Tree Protocol) detects and breaks network loops and provides backup links between switches, bridges or routers. It allows a device to interact with other STP-aware devices in your network to ensure that only one path exists between any two stations on the network. Refer to the user’s guide that comes with your switch for more information.

Use the Multiple STP Conf. screen to configure STP and/or multiple STP settings on the switch.

To open this screen, right-click on the switch in the Device List Panel, and click Configuration > Switch Configuration > Multiple STP Conf..

LABEL DESCRIPTION

Multiple Rapid Spanning Tree Protocol

Tree

This field displays the index number of a spanning tree.

 

 

Active

Select this option to enable the tree.

 

 

Bridge Priority

Priority is used in determining the root device, root port and designated port. The

 

device with the highest priority (lowest numeric value) becomes the RSTP root device.

 

If all devices have the same priority, the device with the lowest MAC address will then

 

become the root device. The allowed range is 0 to 65535 (32768 is the default).

 

The lower the numeric value you assign, the higher the priority for this bridge.

 

Priority determines the root bridge, which in turn determines Hello Time, Max Age

 

and Forward Delay.
