if-range
no spanning-tree cost
This command configures the path
cost to default for the specific port.
if-range
spanning-tree port-priority <0-
240>
This command configures the port
priority for the specific port.
Default: 128.

This command configures the port
priority to default for the specific
port.

Parameter
Description
State
Select Enabled to use Spanning Tree Protocol (STP) or Rapid
Spanning Tree Protocol (RSTP).
Mode
Select to use either Spanning Tree Protocol (STP) or Rapid
Spanning Tree Protocol (RSTP).
Forward Time
This is the maximum time (in seconds) the Switch will wait
before changing states. This delay is required because every
switch must receive information about topology changes
before it starts to forward frames. In addition, each port needs
time to listen for conflicting information that would make it
return to a blocking state; otherwise, temporary data loops
might result. The allowed range is 4 to 30 seconds.
Max Age
This is the maximum time (in seconds) the Switch can wait
without receiving a BPDU before attempting to reconfigure.
All Switch ports (except for designated ports) should receive
BPDUs at regular intervals.
Any port that age out STP information (provided in the last
BPDU) becomes the designated port for the attached LAN. If it
is a root port, a new root port is selected from among the
Switch ports attached to the network. The allowed range is 6
to 40 seconds.
Hello Time
This is the time interval in seconds between BPDU (Bridge
Protocol Data Units) configuration message generations by the
root switch. The allowed range is 1 to 10 seconds.
Priority
Priority is used in determining the root switch, root port and
designated port. The switch with the highest priority (lowest
numeric value) becomes the STP root switch. If all switches
have the same priority, the switch with the lowest MAC
address will then become the root switch.
Enter a value from 0~61440.
The lower the numeric value you assign, the higher the priority
for this bridge.
Priority determines the root bridge, which in turn determines
the Root Hello Time, Root Maximum Age and Root Forwarding
Delay.
Pathcost
Path cost is the cost of transmitting a frame on to a LAN
through that port. It is recommended to assign this value
