This object determines the queuing priority
and drop probability this sequence of ping
packets experience in the switches through
which they pass through.
If the value of this object is set to 'high',
then the corresponding sequence of packets
will experience high queueing priority and
low drop probability in the switches through
which they pass through.
If the value of this object is set to 'low',
then the corresponding sequence of packets
will experience low queueing priority and
higher drop probability in the switches
through which they pass through.
This object cannot be modified if the
corresponding instance of fcPingOperStatus
object has a value of 'inProgress'.
