spanning-tree pathcost method {long | short}
no spanning-tree pathcost method
Syntax Description
Command Default Short.
Command Modes Configuration mode
Command History
Usage Guidelines The long path-cost calculation method uses all 32 bits for path-cost calculations and yields valued in the
range of 2 through 2,00,000,000.
The short path-cost calculation method (16 bits) yields values in the range of 1 through 65535.
Note This command applies only to the Rapid PVST+ spanning tree mode, which is the default mode. When
you are using MST spanning tree mode, the switch uses only the long method for calculating path cost;
this is not user-configurable for MST.
Examples This example shows how to set the default pathcost method to long:
switch(config)# spanning-tree pathcost method long
