3com 5500 User Manual

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 Internet Control Message Protocol (ICMP) to 
test the round trip time (RTT) between the local end and a specified destination 
end for you to judge whether the destination end is reachable.

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 operation tag.

After creating a Remote-ping test group and configuring the test parameters, you 
can perform a Remote-ping test with the test-enable command.

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 pemote-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.

A Remote-ping ICMP test between two switches uses ICMP to test the round trip 
time (RTT) for packets generated by the Remote-ping client.
