externalCost − Defines a metric that indicates the relative cost of
forwarding packets to the specified port list. Port cost can be set
automatically or as a metric value. The default value is auto.

200000000 to determine the external cost. The lower the
number, the greater the probability the port will be chosen to
forward packets.
hellotime <value 1-10> − The time interval between transmission of
messages by the designated port, to other devices on
AN, thus stating that the Switch is still functioning. The
value may be between 1 and 10 seconds. The default is 2 seconds.
