• Admin MST Path Cost – This parameter is used by the MSTP to
determine the best path between devices. Therefore, lower values should
be assigned to ports attached to faster media, and higher values assigned
to ports with slower media. (Path cost takes precedence over port
priority.) (Range: 0 for auto-configuration, 1-65535 for the short path
cost method
15 , 1-200,000,000 for the long path cost method)
By default, the system automatically detects the speed and duplex mode
used on each port, and configures the path cost according to the values
shown below. Path cost “0” is used to indicate auto-configuration mode.
When the short path cost method is selected and the default path cost
recommended by the IEEE 8021w standard exceeds 65,535, the default
is set to 65,535.
The recommended range is listed in Table 11-1 on page 11-19.
The recommended path cost islisted in Table 11-2 on page 11-19.
The default path costs are listed in Table 11-3 on page 11-19.
