Description
Use the stp pathcost-standard command to set the path cost calculation
standard on STP port.
standard on STP port.
The port rate must be obtained first before you can calculate the path cost of a
port as the path cost is associated with the port rate. The three standards use their
own way to work out the port rate, based on which each standard calculates the
port path cost by a certain algorithm.
port as the path cost is associated with the port rate. The three standards use their

port path cost by a certain algorithm.
By default, the legacy standard is applied for the switch Switch 8800 Family.
Example
# Set the DOT1D-1998 as the path cost calculation standard on the STP port.
