11.8.1 Multiple Spanning Tree Protocol Port Configuration
To configure MSTP ports, click Port in the Advanced Application > Spanning Tree Protocol >
MSTP screen.
Active Select this check box to add this port to the MST instance.
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 - see
Table 55 on page 132 for more information.
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.
Cancel Click Cancel to begin configuring this screen afresh.
