
Path Cost : indicates the path cost value that will be
announced by the port to other bridges in the same MSTI
instance. Lower path costs mean higher port speed, and
they are chosen to forward traffic at the expenses of
higher path costs. Allowed values are Auto and Specific. If
Auto is selected, path costs will be calculated based on
port speed capabilities as recommended at the 802.1D
standard. If Specific is selected, path cost used will be the
path cost defined by user at the field allowed in the Path
Cost column. Allowed path costs values are integer values
from 1 to 200000000;

Priority : indicates the priority of the port. If there are two
paths between Bridges with the same path cost, the
priority field will be used to choose which port should
forward traffic. Lower values mean higher priority for the
port. Allowed values are integer numbers from 0 to 240.
