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
Operation Command Description
Enter system view
system-view
—
Configure the path cost
for specified ports
stp interface
interface-list [ instance
instance-id ] cost cost
Required
An MSTP-enabled switch
can calculate path costs
for all its ports
automatically.
Table 1-25 Configure the path cost for a port in Ethernet port view
Operation Command Description
Enter system view
system-view
—
Enter Ethernet port view
interface interface-type
interface-number
—
Configure the path cost
for the port
stp [ instance
instance-id ] cost cost
Required
A MSTP-enabled switch
can calculate path costs
for all its ports
automatically.
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
