11.6 Multiple Spanning Tree Protocol Status
Click Advanced Application > Spanning Tree Protocol in the navigation panel to display
the status screen as shown next. See Section 11.1.4 on page 97 for more information on
MSTP.
" This screen is only available after you activate MSTP on the Switch.
Port This field displays the port number.
* 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.
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 21 on page 96 for more
information.
Add Click Add to save this MST instance 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.
Instance This field displays the ID of an MST instance.
