14.6.1 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. See
Chapter 14 Spanning Tree Protocol
DESCRIPTION
Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this row first to set
the common settings and then make adjustments on a port-by-port basis.
Note: Changes in this row are copied to all the ports as soon as you make them.
Select this check box to add this port to the MST instance.
Configure the priority for each port here.
Priority decides which port should be disabled when more than one port forms a loop in a
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 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 36 on page 132
Click Add to save this MST instance to the OLT's run-time memory. The OLT 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.
Click Cancel to begin configuring this screen afresh.
