Configured in Ethernet interface view, the setting takes effect only on the interface.
Configured in port group view, the setting takes effect on all member ports in the port group.
Configured in Layer 2 aggregate interface view, the setting takes effect only on the aggregate
interface. Configured on a member port in an aggregation group, the setting takes effect only after
the port leaves the aggregation group.
To set the path cost of an MSTP port in a specific MSTI, use this command with the MSTI specified.
Path cost is an important factor in spanning tree calculation. Setting different path costs for a port in
MSTIs allows different VLAN traffic flows to be forwarded along different physical links and enables
VLAN-based load balancing.
The path cost setting of a port can affect the role selection of the port. When the path cost of a port is
changed, the system re-calculates the role of the port and initiates a state transition.
Examples
# In MSTP mode, set the path cost of port Ethernet 1/3 in MSTI 2 to 200.
<Sysname> system-view
[Sysname] interface ethernet 1/3
[Sysname-Ethernet1/3] stp instance 2 cost 200
