Using Ping
The ping command is configurable from normal executive and privileged EXEC mode. Ping returns one
of the following responses:
• Normal response—The normal response (hostname is alive) occurs in 1 to 10 seconds, depending
on network traffic.
• Destination does not respond—If the host does not respond, a No Answer message is returned.
• Unknown host—If the host does not exist, an Unknown Host message is returned.
• Destination unreachable—If the default gateway cannot reach the specified network, a Destination
Unreachable message is returned.
• Network or host unreachable—If there is no entry in the route table for the host or network, a
Network or Host Unreachable message is returned.
To stop a ping in progress, press Ctrl-C.

This example shows how to enter a ping command in privileged EXEC mode specifying the number of
packets, the packet size, and the timeout period:
Switch# ping
