Follow these steps to specify a standard for the device to use when it calculates the default path cost:
To do...
Enter system view
Specify a standard for the device
to use when it calculates the default
path costs of its ports
CAUTION:
If you change the standard that the device uses to calculate the default path costs, you restore the path
costs to the default.
Table 13 shows the mappings between the link speed and the path cost.
