7. Adjust the following parameters as needed.
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 19, “Port Priority Value
Increments” on page 521.
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 65,535. 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 520 andTable 16
on page 520.
8. After making changes, type R until you return to the Main Menu. Then
type S to select Save Configuration Changes.
