long - Specifies 32-bit based values that range from
1-200,000,000. This method is based on the IEEE 802.1w Rapid
Spanning Tree Protocol.
short - Specifies 16-bit based values that range from 1-65535.
This method is based on the IEEE 802.1 Spanning Tree Protocol.

The path cost method is used to determine the best path between
devices. Therefore, lower values should be assigned to ports attached
to faster media, and higher values assigned to ports with slower media.
Note that path cost (page
(page 804).
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.
