In this formula, the link transmission speed is the sum of the speeds of all the unblocked
ports on the aggregated link, which is measured in 100 Kbps.
II. Configure the path costs of ports
Table 1-24 Configure the path cost for specified ports in system view
Enter system view
Configure the path cost
for specified ports
Table 1-25 Configure the path cost for a port in Ethernet port view
Enter system view
Enter Ethernet port view
Configure the path cost
for the port
Changing the path cost of a port may change the role of the port and put it in state
transition. Executing the stp cost command with the instance-id argument being 0 sets
the path cost on the CIST for the port.
III. Configuration example (A)
# Configure the path cost of Ethernet1/0/1 in spanning tree instance 1 to be 2,000.
1) Perform this configuration in system view.
<H3C> system-view
[H3C] stp interface Ethernet1/0/1 instance 1 cost 2000
2) Perform this configuration in Ethernet port view.
<H3C> system-view
[H3C] interface Ethernet1/0/1
[H3C-Ethernet1/0/1] stp instance 1 cost 2000
