Spanning Tree Configuration

The following figures and tables describe Bridge STA 
configuration. 

Switch

When the Switch Becomes Root

Parameter

Default

Description

Usage

Enabled

Enable this parameter to participate in an STA 
compliant network. 

Priority

32,768

Device priority is used in selecting the root 
device, root port, and designated port.  The 
device with the highest priority becomes the 
STA root device. (Remember that the lower the 
numeric value, the higher the priority.) 
However, if all devices have the same priority, 
the device with the lowest MAC address will 
then become the root device.  

Range: 0 - 65535

Parameter Default

Description

Hello Time

2

The time interval (in seconds) at which the root 
device transmits a configuration message. 

The minimum value is 1.  

The maximum value is the lower of 
10 or [(Max. Message Age / 2) -1].
