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 port in spanning tree instance 1 to be 2,000.
Configure in system view.
<Quidway> system-view
[Quidway] stp interface ethernet1/0/1 instance 1 cost 2000
Configure in Ethernet port view.
<Quidway> system-view
[Quidway] interface ethernet1/0/1
[Quidway-Ethernet1/0/1] stp instance 1 cost 2000
IV. Configuration example (B)
# Change the path cost of Ethernet1/0/1 port in spanning tree instance 1 to the default
one calculated with the IEEE 802.1D-1998 standard.
Configure in system view.
