Click Configuration to specify which STP mode you want to activate. Click MRSTP to

 

edit MRSTP settings on the Switch.

Select which STP tree configuration you want to view.

 

 

Bridge

Root refers to the base of the spanning tree (the root bridge). Our Bridge is this Switch.

 

This Switch may also be the root bridge.

 

 

Bridge ID

This is the unique identifier for this bridge, consisting of bridge priority plus MAC address.

 

This ID is the same for Root and Our Bridge if the Switch is the root switch.

 

 

Hello Time

This is the time interval (in seconds) at which the root switch transmits a configuration

(second)

message. The root bridge determines Hello Time, Max Age and Forwarding Delay.

 

 

Max Age (second)

This is the maximum time (in seconds) a switch can wait without receiving a configuration

 

message before attempting to reconfigure.

 

 

Forwarding Delay

This is the time (in seconds) the root switch will wait before changing states (that is,

(second)

listening to learning to forwarding).

 

Note: The listening state does not exist in RSTP.
