Using Ping
Ping returns one of the following responses:
• Normal response—The normal response (hostname is alive) occurs in 1 to 10 seconds depending on
the 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.
Executing Ping
To ping another device on the network from the switch, perform one of these tasks in normal or
privileged mode:
This example shows how to ping a remote host from normal EXEC mode:
Console> ping labsparc
labsparc is alive
Console> ping 72.16.10.3
12.16.10.3 is alive
Console>
This example shows how to ping a remote host using the ping -s option:
Console> ping -s 12.20.5.3 800 10
