Tab. 8.3 RSTP Path-cost (long)
To decide the path-cost calculation method, use the following command.
Command Mode Description
spanning-tree pathcost method
long Selects the method for calculating a RSTP path-cost:
long: 32 bits of RSTP path-cost (IEEE 802.1D-2004).
spanning-tree pathcost method
short
Bridge
Selects the method for calculating a STP path-cost:
short: 16bits of STP path-cost (IEEE 802.1D-1998).
To delete a configured method for caculating the path-cost and return the configuration to
the default, use the following command.
Command Mode Description
no spanning-tree pathcost
method
Bridge
Deletes the configured method of path-cost. (default:
short)
When the route decided by path-cost gets overloading, you would better take another
route. Considering these situations, it is possible to configure the path-cost of root port so
that user can configure a route manually.
To configure the path-cost, use the following command.
Command Mode Description
spanning-tree port PORTS cost
<1-200000000>
Configures path-cost to configure route:
PORTS: port number.
1-200000000: the path cost value.
no spanning-tree port PORTS
cost
Bridge
Deletes the configured path-cost, enter the port num-
ber.
8.3.6.2 Edge Ports
Edge ports are defined that the ports are connected to a nonbridging device. There are no
switches or spanning-tree bridges directly connected to the edge port.
