Test parameter
Description
Source interface
(source-interface)
z
For a DHCP test, you must specify a source interface, which will be
used by the HWPing client to send DHCP requests. If no source
interface is specified for the DHCP test, the test will not succeed.
z
After a source interface is specified, the HWPing client uses this
source interface to send DHCP requests during the DHCP test.
z
The IP address of the specified source interface will be used as the
source IP address of DHCP requests.
Source address
(source-ip)
For HWPing tests other than DHCP tests, you can specify a source IP
address for test packets, which will be used by the server as the
destination address of response packets.
Source port
(source-port)
For HWPing tests other than ICMP, DHCP and DNS, you can specify a
source port number for test packets, which will be used by the server as
the destination port number of response packets.
Test type (test-type)
z
You can use HWPing to test a variety of protocols, see
for
details.
z
To perform a type of test, you must first create a test group of this
type. One test group can be of only one HWPing test type.
z
If you modify the test type of a test group using the test-type
command, the parameter settings, test results, and history records of
the original test type will be all cleared.
Number of probes per
test (count)
For tests except jitter test, only one test packet is sent in a probe. In a
jitter test, you can use the jitter-packetnum command to set the number
of packets to be sent in a probe.
Packet size (datasize)
z
For ICMP/UDP/jitter test, you can configure the size of test packets.
z
For ICMP test, the ICMP packet size refers to the length of
ECHO-REQUEST packets (excluding IP and ICMP headers)
Padding string for the
test packet (datafill)
In ICMP, UDP and jitter tests, the system should stuff the data field of
each transmitted ICMP message. The stuffing character string ranges
from 1 to 230 characters, including spaces.
If the size of a test datagram is smaller than that of the configured
stuffing character string, only a portion of the string will be used for
stuffing. If the size of the test datagram is larger, the string will be used
cyclically for stuffing. Suppose a stuffing string, “abcde”, is configured. If
the test datagram size is 3, only “abc” will be used for stuffing; if it is 8,
the string “abcdeabc" will be used.
Routing table
bypass(sendpacket
passroute)
With routing table bypass, a remote host can bypass the normal routing
tables and send ICMP packets directly to a host on an attached network.
If the host is not on a directly-attached network, an error is returned. You
can use this function when pinging a local host on an VLAN interface that
has no route defined.
TTL of HWPing test
packets (ttl)
It is equal to the argument “-h” in a ping command.
Maximum number of
history records that can
be saved
(history-records)
This parameter is used to specify the maximum number of history
records that can be saved in a test group. When the number of saved
history records exceeds the maximum number, HWPing discards some
earliest records.
Automatic test interval
(frequency)
This parameter is used to set the interval at which the HWPing client
periodically performs the same test automatically.
Probe timeout time
(timeout)
z
The probe timeout timer is started after the HWPing client sends out a
test packet.
z
This parameter is in seconds.
Type of service (tos)
Type of service is the value of the ToS field in IP header in the test
packets.
