Default
The device automatically calculates the path costs of ports in each spanning tree based on the
corresponding standard.

Default command level
2: System level
Parameters
instance instance-id
: Sets the path cost of the ports in a particular MSTI. The minimum value of
instance-id
is 0, representing the CIST, and the maximum value of
instance-id
is 15.
cost
: Specifies the path cost of the port, with an effective range that depends on the path cost
calculation standard adopted.
•
With the IEEE 802.1d-1998 standard selected for path cost calculation, the value range for the
cost
argument is 1 to 65535.
•
With the IEEE 802.1t standard selected for path cost calculation, the value range for the
cost
argument is 1 to 200000000.
•
With the private standard selected for path cost calculation, the value range for the
cost
argument is 1 to 200000.
