Click Advanced Application > Spanning Tree Protocol in the navigation panel

more information on MSTP. 

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

Figure 69   Advanced Application > Spanning Tree Protocol > Status: MSTP 

Edge

Select this check box to configure a port as an edge port when it is 
directly attached to a computer. An edge port changes its initial STP 
port state from blocking state to forwarding state immediately without 
going through listening and learning states right after the port is 
configured as an edge port or when its link status changes.

Note: An edge port becomes a non-edge port as soon as it receives 

a Bridge Protocol Data Unit (BPDU).

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.
