Chapter 13 Spanning Tree Protocol Table 31 Advanced Application > Spanning Tree Protocol > MSTP (continued) LABEL Bridge Priority DESCRIPTION Set the priority of the Switch for the specific spanning tree instance. The lower the number, the more likely the Switch will be chosen as the root bridge within the spanning tree instance. VLAN Range Enter priority values between 0 and 61440 in increments of 4096 (thus valid values are 4096, 8192, 12288, 16384, 20480, 24576, 28672, 32768, 36864, 40960, 45056, 49152, 53248, 57344 and 61440). 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: Enabled VLAN(s) Port * • 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. • Clear - to remove all VLAN(s) from being mapped to this MST instance. This field displays which VLAN(s) are mapped to this MST instance. 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. Active Priority Path Cost Add Cancel Instance VLAN Active Port 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 24 on page 118 for more information. 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 nonvolatile 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. MES-3528 User's Guide 135

Bridge Priority
Set the priority of the Switch for the specific spanning tree instance. The
lower the number, the more likely the Switch will be chosen as the root
bridge within the spanning tree instance.
Enter priority values between 0 and 61440 in increments of 4096 (thus
valid values are 4096, 8192, 12288, 16384, 20480, 24576, 28672,
32768, 36864, 40960, 45056, 49152, 53248, 57344 and 61440).
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.
Clear
- to remove all VLAN(s) from being mapped to this 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 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
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 24 on
page 118
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.
VLAN
This field displays the VID (or VID ranges) to which the MST instance is
mapped.
Active Port
This field display the ports configured to participate in the MST instance.
