6. 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 17, ”Port Priority
Value Increments” on page 254.
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 15 on page 253 and Table 16 on page 253.
