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.
