6. Adjust the settings as needed. The parameters are explained below.
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 334.
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. For the default values used by Automatic Update, refer
Table 15 on page 333 and Table 16 on page 333.
3 - Point-to-Point
This parameter defines whether the port is functioning as a point-
to-point port. For an explanation of this parameter, refer to Point-
to-Point Ports and Edge Ports on page 336.
4 - 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.
