VLAN Range
Enter the start of the VLAN ID range that you want to add or remove from the
VLAN range edit area in the Start field. Enter the end of the VLAN ID range that
you want to add or remove from the VLAN range edit area in the End field.
Next click:
•
Add - to add this range of VLAN(s) to be mapped to the MST instance.
•
Remove - to remove this range of VLAN(s) from being mapped to the MST
instance.
•

Enabled VLAN(s)
This field displays which VLAN(s) are mapped to this MST instance.
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
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
