Ping echo request transmission timing
Two types of echo request transmission timing are available: Type 1 and
Type 2. (Default: Type 2)
Type1
Type 1 sets the interval for a definite period of time between ping echo
requests regardless of the timeout occurrence.
Set the interval time greater than or equal to the timeout time (Interval
Timeout), when Type 1 is chosen.
