Disabled -Disable the RSTP.

 

 

 

 

 

 

System Priority -

Specifies the bridge priority value. When switches or bridges are running STP,

 

 

 

each is assigned a priority. After exchanging BPDUs, the switch with the lowest

 

 

 

priority value becomes the Root Bridge. The bridge priority value is provided in

 

 

 

increments of 4096 (4K increments). For example, 0, 4096, 8192, etc.

 

 

 

The default value is 32768.

 

 

 

 

 

 

Hello Time

Specifies the device Hello Time. The Hello Time indicates the amount of time in

 

 

 

seconds a root bridge waits between configuration messages.

 

 

 

Value Range : 1-10

 

 

 

The default is 2 seconds.

 

 

 

 

 

 

Max Age

Specifies the device Maximum Age Time. The Maximum Age Time indicates the

 

 

 

amount of time in seconds a bridge waits before sending configuration messages.

 

 

 

Value Range : 6-40

 

 

 

The default max age is 20 seconds.

 

 

 

 

 

 

Forward Delay

Specifies the device forward delay time. The Forward Delay Time indicates the

 

 

 

amount of time in seconds a bridge remains in a listening and learning state

 

 

 

before forwarding packets.

 

 

 

Value Range : 4-30

 

 

 

The default is 15 seconds.
