At the lower portion of this page, the user can configure the Settings of this function. For RSTP,

you can configure:

 

 

 

 

 

Protocol of Redundancy

Bridge priority

 

 

 

 

 

 

 

Setting

Description

 

Factory Default

 

 

 

 

 

Increase this device’s bridge

 

 

 

 

 

 

 

priority by selecting a lower

 

 

 

 

 

 

Numerical value

number. A device with a higher

 

 

 

 

 

 

bridge priority has a greater

32768

 

 

 

 

selected by user

 

 

 

 

chance of being established as the

 

 

 

 

 

 

 

 

 

 

 

 

 

 

root of the Spanning Tree

 

 

 

 

 

 

 

topology.

 

 

 

 

Forwarding Delay

 

 

 

 

 

 

 

 

 

 

 

 

 

Setting

Description

 

Factory Default

 

 

 

 

Numerical value

The amount of time this device

 

15 (sec.)

 

 

 

waits before checking to see if it

 

 

 

 

input by user

 

 

 

 

should change to a different state.

 

 

 

 

 

 

 

 

 

 

 

Hello time (sec.)

 

 

 

 

 

 

 

 

 

 

 

 

 

Setting

Description

 

Factory Default

 

 

 

 

 

The root of the Spanning Tree

 

 

 

 

 

 

 

topology periodically sends out a

 

 

 

 

 

 

Numerical value

“hello” message to other devices

 

 

 

 

 

 

on the network to check if the

2

 

 

 

 

input by user

topology is healthy. The “hello

 

 

 

 

 

 

 

 

 

 

 

time” is the amount of time the

 

 

 

 

 

 

 

root waits between sending hello

 

 

 

 

 

 

 

messages.

 

 

 

 

Max. Age (sec.)

 

 

 

 

 

 

 

Setting

Description

 

Factory Default

 

 

 

 

 

If this device is not the root, and it

 

 

 

 

 

 

 

has not received a hello message

 

 

 

 

 

 

 

from the root in an amount of time

 

 

 

 

 

 

Numerical value

equal to Max. Age, then this

 

 

 

 

 

 

device will reconfigure itself as a

20

 

 

 

 

input by user

root. Once two or more devices on

 

 

 

 

 

 

 

 

 

 

 

the network are recognized as a

 

 

 

 

 

 

 

root, the devices will renegotiate

 

 

 

 

 

 

 

to set up a new Spanning Tree

 

 

 

 

 

 

 

topology.
