MES3500-24/24F User’s Guide

Click Advanced Application > Spanning Tree Protocol in the navigation panel to display the 
status screen as shown next. See 

 for more information on MRSTP. 

Note: This screen is only available after you activate MRSTP on the Switch. 

Advanced Application > Spanning Tree Protocol > Status: MRSTP 

The following table describes the labels in this screen.  

Apply

Click Apply to save your changes to the Switch’s run-time memory. The Switch loses 
these changes if it is turned off or loses power, so use the Save link on the top navigation 
panel to save your changes to the non-volatile memory when you are done configuring.

Cancel

Click Cancel to begin configuring this screen afresh.

Advanced Application > Spanning Tree Protocol > Status: MRSTP 

Configuration

Click Configuration to specify which STP mode you want to activate. Click MRSTP to 
edit MRSTP settings on the Switch. 

Tree

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 
(second)

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

This is the time (in seconds) the root switch will wait before changing states (that is, 
listening to learning to forwarding).

Note: The listening state does not exist in RSTP.
