13.6.1 Multiple Spanning Tree Protocol Port Configuration
Click Advanced Application > Spanning Tree Protocol > MSTP > Port in the navigation panel to display
the status screen as shown next.
Priority Configure the priority for each port here.
Priority decides which port should be disabled when more than one port forms a loop in the
Switch. Ports with a higher priority numeric value are disabled first. The allowed range is
between 0 and 255 and the default value is 128.
Path Cost Path cost is the cost of transmitting a frame on to a LAN through that port. It is recommended
to assign this value according to the speed of the bridge. The slower the media, the higher the
cost.
Add Click this to create a new entry or to update an existing one.
This saves your changes to the Switch’s run-time memory. The Switch loses this change 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.
