To configure the path cost of a port:

Step	Command	Remarks
1. Enter system view.	system-view	N/A
2. Enter Layer 2 Ethernet or aggregate interface view.	interface interface-type interface-number	N/A
3. Configure the path cost of the ports.	In STP/RSTP mode:stp cost cost In PVST mode:stp vlan vlan-id-list cost cost In MSTP mode:stp [ instance instance-list ] cost cost	By default, the system automatically calculates the path cost of each port.
