8. Adjust the following parameters as necessary.
1 - Port Priority
This parameter is used as a tie breaker when two or more ports are
determined to have equal costs to the root bridge. The range is 0 to
240 in increments of 16. The default value is 8 (priority value 128). For
a list of the increments, refer to Table 15, “Port Priority Value
Increments” on page 529.
2 - Port Cost
The spanning tree algorithm uses the cost parameter to decide which
port provides the lowest cost path to the root bridge for that LAN. The
range is 0 to 20,000,000. The default setting is Automatic Update,
which sets port cost depending on the speed of the port. The
Automatic Update default values are shown in Table 13 on page 529
and Table 14 on page 529.
3 - Point-to-Point
This parameter defines whether the port is functioning as a point-to-
point port. The possible settings are Yes, No, and Auto Detect. For an
explanation of this parameter, refer to “Point-to-Point and Edge Ports”
on page 531.
