R21xx-HP FlexFabric 11900 Layer 2 LAN Switching Command Reference

120
When the setting is configured in Layer 2 Ethernet interface view, it takes effect only on that interface.
When the setting is configured in Layer 2 aggregate interface view, it takes effect only on the aggregate
interface.
When the setting is configured on a member port in an aggregation group, it takes effect only after the
port leaves the aggregation group.

stp cost
Use stp cost to set the path cost of the port or ports.
Use undo stp cost to restore the default.
Syntax
stp [ instance instance-list ] cost cost
undo stp [ instance instance-list ] cost
Default
The device automatically calculates the path costs of ports in each spanning tree based on the
corresponding standard.

Parameters
instance instance-list: Sets the path cost of the ports in the MSTIs that are specified by an instance list, in
the format of instance-list = { instance-id [ to instance-id ] }&<1-10>, where &<1-10> indicates that you
can specify up to 10 instances or instance ranges. The value range for the instance-id argument is 0 to
4094, and the value 0 represents the CIST.
cost: Specifies the path cost of the port, with an effective range that depends on the path cost calculation
standard that is adopted.
• When the IEEE 802.1d-1998 standard is selected for path cost calculation, the value range for the
cost argument is 1 to 65535.
• When the IEEE 802.1t standard is selected for path cost calculation, the value range for the cost
argument is 1 to 200000000.
