Section IV: Spanning Tree Protocols 499
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 16, “Port Priority Value
Increments” on page 488.
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. For the default
values used by Automatic Update, refer Table 12 on page 486 and
Table 13 on page 486.
All changes are immediately activated on the switch.
7. After making changes, type R until you return to the Main Menu. Then
