MPX200 ping command

The ping command is the most basic network troubleshooting tool that is available to troubleshoot
FCIP route problems. This command runs a diagnostic in which a message is sent to a destination,
the destination echoes a reply, and the command returns the amount of time it took to reach the
destination and back.
For troubleshooting an intermittent FCIP link run the ping command for an extended period of time,
recording the output. The output should be evaluated looking for large deviations in the ping-time or
lost-packets. Also use the maximum packet-size for the ping test; using the 56-byte default packet
size is not a typical packet size using for FCIP.
