HWPing is a network diagnostic tool used to
test the performance of protocols (only ICMP by far) running on network. It is
an enhanced alternative to the ping command.
HWPing test group is a set of HWPing test parameters.
A test group contains several test parameters and is uniquely identified by an
administrator name plus a test tag.
You can perform an HWPing test after
creating a test group and configuring the test parameters.
Different from the ping command,
HWPing does not display the round trip time (RTT) and timeout status of each
packet on the console terminal in real time. You need to execute the display
hwping command to view the statistic results of your HWPing test operation.
HWPing allows setting the parameters of HWPing test groups and starting HWPing test
operations through network management system.

Illustration for HWPing
The configuration tasks for HWPing include:
l
Enabling HWPing Client
l
Creating test group
l
Configuring test parameters
The test parameters that you can configure
include:
1)
Destination IP address
It is equivalent to the destination IP
address in the ping command.
2)
Test type
Currently, HWPing supports only one test
type: ICMP.
3)
Number of test packets to be sent in a test
If this parameter is set to a number greater
than 1, the system sends the second test packet once it receives a response to
the first one, or when the test timer times out if it receives no response
after sending the first one, and so forth until the last test packet is sent
out. This parameter is equivalent to the –n keyword in the ping
command.
4)
Automatic test interval
This parameter is used to enable the system
to automatically perform the same test at regular intervals.
5)
Test timeout time
Test timeout time is the duration while the
system waits for an ECHO-RESPONSE packet after it sends out an ECHO-REQUEST
packet. If no ECHO-RESPONSE packet is received within this duration, this test
is considered a failure. This parameter is similar to the -t keyword in
the ping command, but has a different unit (the -t keyword in the
ping command is in milliseconds, while the timeout time in the HWPing
command is in seconds).

HWPing Configuration
After the above HWPing configuration, you
can execute the display command in any view to display the information
of HWPing test operation status to you can verify the configuration effect.

I. Network requirement
Perform an HWPing ICMP test between two
switches. Like a ping test, this test uses ICMP to test the RTTs of data
packets between the source and the destination.
