Description

Spanning Tree

Enabled

Enable this parameter to participate in an STA

Protocol

 

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.

 

 

However, if all devices have the same priority, the

 

 

device with the lowest MAC address will then

 

 

become the root device.

 

 

Enter a value from 0 - 65535.

 

 

Remember that the lower the numeric value, the

 

 

higher the priority.

Hello Time

2

Time interval (in seconds) at which the root device

 

 

transmits a configuration message.

 

 

The minimum value is1.

 

 

The maximum value is

 

 

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

Max (Message) Age

20

The maximum time (in seconds) a device can wait

 

 

without receiving a configuration message before

 

 

attempting to reconfigure. All device ports (except

 

 

for designated ports) should receive configuration

 

 

messages at regular intervals. Any port that ages

 

 

out STA information (provided in the last

 

 

configuration message) becomes the designated

 

 

port for the attached LAN. If it is a root port, a new

 

 

root port is selected from among the device ports

 

 

attached to the network.

 

 

The minimum value is

 

 

the higher of 6 or [2 x (Hello Time + 1)].

 

 

The maximum value is

 

 

the lower of 40 or [2 x (Forward Delay - 1)].

Forward Delay

15

The maximum time (in seconds) the root device

 

 

will wait before changing states (i.e., listening to

 

 

learning to forwarding). This delay is required

 

 

because every device must receive information

 

 

about topology changes before it starts to forward

 

 

frames. In addition, each port needs time to listen

 

 

for conflicting information that would make it

 

 

return to a blocking state; otherwise, temporary

 

 

data loops might result.

The maximum value is 30. The minimum value is

the higher of 4 or [(Max. Message Age / 2) + 1].
