HWPing is a network diagnostic tool used to
test the performance of protocols (only ICMP by far) operating 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.
Being 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 administrators to set the parameters of HWPing test groups and
start HWPing test operations.
Figure 1-1 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 sent in a test
If this parameter is set to a number
greater than one, 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 allow the system
to automatically perform the same test at regular intervals.
5)
Test timeout time
Test timeout time is the time 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 time, 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 ms, while the timeout time in the HWPing command is in
seconds).

1.2.3 Displaying HWPing Configuration
After the above HWPing configurations, you
can execute the display command in any view to display the information
of operation status through which 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.
