Description
Time To Live (TTL). Specifies number of hops (hop is
one step, from one router to the next, on the path of a
datagram on an IP network), which the Echo Request
message may be routed over. The value is set by using
TTL field in IP header. Valid value range is from 1 to
255.
Default value: 64
The Type Of Service (TOS) is for internet service
quality selection. The type of service is specified along
the abstract parameters precedence, delay, throughput,
and reliability. These abstract parameters are to be
mapped into the actual service parameters of the
particular networks the datagram traverses. Minimum
and maximum values for TOS are 0 and 255
respectively. Refer to RFC 791 and RFC 2474 which
obsoletes RFC 791 for TOS defined values.
Default value: 0
Specifies the amount of time, in milliseconds, to wait
for the Echo Reply message that corresponds to a sent
Echo Request message, measured after Echo Request
message was sent. If the Echo Reply message is not
received within the time-out, +MPINGSTAT
unsolicited response, with <status> equal to 1, will be
sent to DTE. Valid value range is from 500 ms to
600,000 ms (10 minutes).
Default value: 4000
