Parameter
interface-list: Ethernet port list, containing multiple Ethernet ports and expressed
as interface-list = { interface-type interface-number [ to interface-type
interface-number ] }&<1-10>. For detail descriptions of interface-type and
interface-number parameters, refer to the corresponding descriptions in Port
Command Manual. &<1-10> means that the preceding parameters can be
entered up to 10 times.
instance-id: Specifies the spanning tree instance ID, ranging from 0 to 48. The
instance 0 represents CIST.
cost: Port path cost. Its range depends on the selected standard of path cost.
Description
Use the stp interface cost command to configure the path cost of the specified
port on the specified MSTI in system view.
Use the undo stp interface cost command to restore the path cost of the
specified port on the specified MSTI to the default value in system view.
By default, switch automatically calculates the path costs of a port on different
MSTIs based on corresponding standard.
You may specify the instance-id parameter as 0 to configure CIST path cost of the
port. The path cost has effect on the port role selection. You can configure
different path costs for different MSTIs on a port. Thus the traffic from different
VLANs can run over different physical links, thereby implementing the VLAN-based
load-balancing. MSTP will recalculate the port role and transit its state, upon the
port path cost changes.
Related command: stp cost.

# Set the path cost of Ethernet 2/1/3 on MSTI 2 to 400 in system view.
