Testing Tools for Network Connection
239
After the synchronization of the whole fabric, a great deal of terminal display is
generated. You are recommended not to enable the information synchronization
switch of the whole fabric. If you enabled the information synchronization switch,
after the synchronization information statistics and detection, you must execute
the
undo info-center switch-on
command to disable the Switch in time.
Display Diagnostic Information
You can collect information about the Switch to locate the source of a fault.
However, each module has its corresponding
display
command, which makes it
difficult to collate all the information needed. In this case, you can use
display
diagnostic-information
command.
You can perform the following operations in all views.

ping
The
ping
command can be used to check the network connection and if the host
is reachable.
Perform the following operation in all views.
Table 268
The ping Command
The output of the command includes:
■
The response to each ping message. If no response packet is received when
time is out, ”Request time out” information appears. Otherwise, the data
bytes, the packet sequence number, TTL, and the round-trip time of the
response packet will be displayed.
■
The final statistics, including the number of the packets the Switch sent out
and received, the packet loss ratio, the round-trip time in its minimum value,
mean value and maximum value.
Test Periodically if the IP Address is Reachable
You can use the
end-station polling ip-address
command in System View to
configure the IP address requiring periodical testing.
Perform the following configuration in System View.
