following:

Completed - requested number of iterations is completed
Alloc Failed - failed to allocate resources
The range is 0-65535 minutes. The default is 10 minutes.

The default is 64 bytes. The range is 1-1400.
timeout
Period in seconds before determining that a transmission has not been
replied to. The range is 1-60. The default is 20 seconds.

time in milliseconds, the ping destination and its status, the ping count you
specified, any timeouts that may have occurred, and maximum, minimum
and average round trip times. Can choose either background or verbose, not
both. A round trip time of -1 indicates ping resolution failed. The default is
NO.
