DESCRIPTION
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.
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 the ONU. 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
information.
Click Add to save this MST instance to the ONU's run-time memory. The ONU
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.
This field displays the ID of an MST instance.
This field displays the VID (or VID ranges) to which the MST instance is mapped.
This field display the ports configured to participate in the MST instance.
Check the rule(s) that you want to remove in the Delete column and then click the
Delete button.
Click Cancel to begin configuring this screen afresh.
