Restore the default number of messages
sent for a test.
By default, one message is sent for a test.
8) Configuring ICMP datagram size
ICMP datagram size refers to the size of the ECHO-REQUEST message transmitted
for an ICMP test, excluding the IP and the ICMP headers. The argument discussed in
this subsection is equal to the argument "-s" in a ping command.
Perform the following configurations in HWPing test group view.
Table 4-12 Configure an ICMP datagram size
Configure an ICMP datagram size.
Restore the default ICMP datagram size.
The size argument defaults to 0. Normally, you may set the size of a test packet to 56
bytes for an ICMP test, 100 bytes for an UDP test, and 28 to 100 bytes for a jitter test.
The size of the packet for a jitter test can only take a value in the range 28 to 100 bytes.
9) Configuring auto-test interval
Configured with the auto-test feature, the system will automatically test the connection
of a specified type at a regular interval.
Perform the following configurations in HWPing test group view.
Table 4-13 Configure auto-test interval
Configure an auto-test interval.
Disable auto-test.
By default, auto-test interval is set to 0, i.e., only one test is performed.
10) Configuring test timeout time
Test timeout time refers to the period that the system waits for ECHO-RESPONSE after
sending an ECHO-REQUEST message, upon the expiration of which the system will
regard the destination unreachable. The argument discussed in this subsection is
equal to the argument "-t" in a ping command, but in a different time unit.
Perform the following configurations in HWPing test group view.
