ping

Use this command to send echo messages to another host.

When data packets copied to cpu due to destination lookup fail, both data packets and icmp echo request packets processed in cpu through same cpu queue and it may happen that ping fails due to congestion. In such cases, to check connectivity, please use interactive ping command and update tos value 192. Refer ping (interactive) for the interactive ping command.
