PING Test
The D-View network management system provides a test facility that verifies whether or
not the management console has good communication link with a particular device on
the network. This facility implements the Packet InterNet Groper (PING) program for
use on TCP/IP internets to test reachability of destinations. PING verifies connectivity
of a device by sending ICMP echo request packets to it and then waits for the ICMP
echo response packets from the device. For every request, PING expects a response;
otherwise, a problem exists in the connection. In addition to sending a series of ICMP
echo requests and capturing responses, PING also provides statistics for lost
datagrams. These values can be used to determine the reliability of the connection. If
you suspect a problem with a network device, you can run this utility to determine
whether or not the management console can communicate with the device.
