Remote-ping
Overview
Introduction to
Remote-ping
Remote-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 the remote-ping client and sometimes the corresponding
remote-ping servers to perform various remote-ping tests. All remote-ping tests
are initiated by the 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.
