Click SWITCHING > Spanning Tree Protocol > MSTP > MSTP Port Setup to display the screen as shown next.
Figure 311 SWITCHING > Spanning Tree Protocol > MSTP > MSTP Port Setup (Standalone Mode)
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.
Note: Set the value to 0 to use the auto path cost you set in the SWITCHING >
Spanning Tree Protocol > Spanning Tree Setup screen (see Auto Path-cost
Mode).
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.
Clear Click Clear to clear the fields to the factory defaults.
Cancel Click Cancel to not save the configuration you make and return to the last screen.
