4. Adjust the parameters as needed. The parameters are described
below.
Port Priority
This parameter is used as a tie breaker when two or more ports are
determined to have equal costs to the regional root bridge. The
range is 0 to 240 in increments of 16. The default value is 8 (priority
value is 128). For a list of the increments, refer to Table 17 on page
334.
Port Internal Path Cost
The port cost of the port if the port is connected to a bridge which
is part of the same MSTP region. The range is 0 to 200,000,000. The
default setting is Auto-detect, which sets port cost depending on
the speed of the port. The default Auto-detect settings are listed
in Table 18 on page 381 and Table 19 on page 381.
Edge Port
This parameter defines whether the port is functioning as an edge
port. For an explanation of this parameter, refer to Point-to-Point
Ports and Edge Ports on page 336.
