Configuring path costs of ports
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter Ethernet interface view or
Layer 2 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 MSTP mode:
stp [ instance instance-id ] cost
cost
Use either command.
By default, the system
automatically calculates the
path cost of each port.
NOTE:
When the path cost of a port changes, the system re-calculates the role of the port and initiates a state
transition.
Configuration example
# In MSTP mode, specify the device to calculate the default path costs of its ports by using IEEE
802.1d-1998, and set the path cost of GigabitEthernet 0/3 to 200 on MSTI 2.
