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 7, RSTP Port
Priority Value Increments on page 95.
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 Auto-
detect, which sets port cost depending on the speed of the port.
Default values are 2 000 000 for 10 Mbps ports, 200 000 for a 100
Mbps ports, and 20 000 for one gigabit ports.
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 97.
