cost
: path cost to be set for the port. The range of the
cost
argument varies with the
standard used for calculating the default path cost of a port as follows:
With IEEE 802.1D-1998 standard selected, the path cost of an Ethernet port ranges
from 1 to 65535.
With IEEE 802.1t standard selected, the path cost of an Ethernet port ranges from
1 to 200000000.
The argument ranges from 1 to 200000000, and the default value is auto
（
