Usage guidelines
Path cost is an important factor in spanning tree calculation. Setting different path costs for a port in
MSTIs allows VLAN traffic flows to be forwarded along different physical links. This results in
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 calculates the role of the port and initiates a state transition.
If this command is configured in Layer 2 Ethernet interface view, it takes effect only on that interface.
If this command is configured in Layer 2 aggregate interface view, it takes effect only on the
aggregate interface.
If this command is configured on a member port in an aggregation group, is takes effect only after the
port leaves the aggregation group.
If you do not specify an MSTI or VLAN, this command sets the path cost of a port in the MSTP CIST
or in the STP or RSTP spanning tree.
Examples
# In MSTP mode, set the path cost to 200 for GigabitEthernet 1/0/1 in MSTI 2.
<Sysname> system-view

[Sysname-GigabitEthernet1/0/1] stp instance 2 cost 200
# In PVST mode, set the path cost to 200 for GigabitEthernet 1/0/1 in VLAN 2.
<Sysname> system-view
