The path cost methods apply to all spanning tree modes (STP, RSTP and MSTP).
Specifically, the long method can be applied to STP since this mode is
supported by a backward compatible mode of RSTP.
Example
Console(config)#spanning-tree pathcost method long
Console(config)#
spanning-tree priority
This command configures the spanning tree priority globally for this switch. Use

Command Usage
Bridge priority is used in selecting the root device, root port, and designated port.
The device with the highest priority (i.e., lower numeric value) becomes the STA
root device. However, if all devices have the same priority, the device with the
lowest MAC address will then become the root device.
Example
Console(config)#spanning-tree priority 40960
Console(config)#
