8. Adjust the following parameters as necessary.
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 6 on page 169.
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 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.
Point-to-Point
This parameter defines whether the port is functioning as a point-
to-point port. The possible settings are Yes, No, and Auto-Detect.
For an explanation of this parameter, refer to “Point-to-Point and
Edge Ports” in Chapter 16, “STP and RSTP” in the AT-S63
Management Software Menus Interface User’s Guide.
Edge Port
This parameter defines whether the port is functioning as an edge
port. The possible settings are Yes and No. For an explanation of
this parameter, refer to “Point-to-Point and Edge Ports” in Chapter
16, “STP and RSTP” in the AT-S63 Management Software Menus
Interface User’s Guide.
