Trap
This parameter is used to set the interval at which the
HWPing client periodically performs the same test
automatically.
The probe timeout timer is started after the HWPing client
sends out a test packet.
This parameter is in seconds.
Type of service is the value of the ToS field in IP header in
the test packets.
This parameter is used to specify a DNS domain name in a
HWPing DNS test group.
This parameter is used to set the DNS server IP address in a
HWPing DNS test group.
This parameter is used to set the type of HTTP interaction
operation between HWPing client and HTTP server.
This parameter is used to set the type of FTP interaction
operation between HWPing client and FTP server.
The two parameters are used to set the username and
password to be used for FTP operation.
Name of a file to be transferred between HWPing client and
FTP server
Jitter test is used to collect statistics about delay jitter in
UDP packet transmission
In a jitter probe, the HWPing client sends a series of
packets to the HWPing server at regular intervals (you
can set the interval). Once receiving such a packet, the
HWPing server marks it with a timestamp, and then
sends it back to the HWPing client. Upon receiving a
packet returned, the HWPing client computes the delay
jitter time. The HWPing client collects delay jitter statistics
on all the packets returned in the test. So, the more
packets a jitter probe sends, the more accurate the jitter
statistics is, but the longer time the jitter test costs.
Each jitter probe will send multiple UDP test packets at
regular intervals (you can set the interval). The smaller the
interval is, the faster the test is. But a too small interval may
somewhat impact your network.
A HWPing test will generate a Trap message no matter
whether the test successes or not. You can use the Trap
switch to enable or disable the output of trap messages.
You can set the number of consecutive failed HWPing
tests before Trap output. You can also set the number of
consecutive failed HWPing probes before Trap output.
