Remote-Ping
Overview
Introduction to
Remote-Ping
Remote-Ping (pronounced Hua’Wei Ping) is a network diagnostic tool. It is used to
test the performance of various protocols running in networks. Remote-Ping
provides more functions than the
ping command.
■
The ping command can only use the ICMP protocol to test the round trip time
(RTT) between this end and a specified destination end for the user to judge
whether the destination end is reachable.
■
Besides the above function of the ping command, Remote-Ping can also
provide other functions, such as testing the status (open/close) of a
DHCP/FTP/HTTP/SNMP server and the response time of various services.
You need to configure Remote-Ping client and sometimes the corresponding
Remote-Ping servers as well to perform various Remote-Ping tests.
All Remote-Ping tests are initiated by Remote-Ping client and you can view the test
results on Remote-Ping client only.
When performing a Remote-Ping test, you need to configure a Remote-Ping test
group on the Remote-Ping client. A Remote-Ping test group is a set of
Remote-Ping test parameters. A test group contains several test parameters and is
uniquely identified by an administrator name and a test tag.
After creating a Remote-Ping test group and configuring the test parameters, you
can then perform a Remote-Ping test by the
test-enable command.
■
Being different from the ping command, Remote-Ping does not display the
RTT or timeout status of each packet on the Console terminal in real time. To
view the statistic results of your Remote-Ping test operation, you need to
execute the
display Remote-Ping command.
■
Remote-Ping also allows you to set parameters for Remote-Ping test groups,
start Remote-Ping tests and view statistical test results through a network
management device.
