Test parameter Description
Number of jitter test packets to be sent per
probe (jitter-packetnum)
z
Jitter test is used to collect statistics about delay jitter in UDP
packet transmission
z
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.
Interval to send jitter test packets
(jitter-interval)
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.
Trap
z
A HWPing test will generate a Trap message no matter
whether the test successes or not. You can use the Trap
device to enable or disable the output of trap messages.
z
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.
HWPing Configuration
The TCP/UDP/jitter tests need the cooperation of HWPing client and HWPing Server, Other types of
tests need to configure HWPing client and corresponding different servers.
Configuration on a HWPing Server
You can enable both the HWPing client and HWPing server functions on a device, that is, the device
can serve as a HWPing client and server simultaneously.
HWPing server configuration tasks
Complete the following tasks to configure the HWPing server:
Task Remarks
Enable the HWPing server
function The HWPing server function is needed only for jitter, TCP,
and UDP tests.
HWPing server
configuration
Configure a listening service
on the HWPing server
You can configure multiple TCP/UDP listening services on
one HWPing server, with each listening service
corresponding to a specific destination IP address and port
number.
HWPing server configuration
The following table describes the configuration on HWPing server, which is the same for HWPing test
types that need to configure HWPing server.
Follow these steps to configure the HWPing server:
