Using Ping
Executing Ping
To ping another device on the network from the switch, perform one of these tasks in normal EXEC mode
or privileged EXEC 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 -s option:
Console> ping -s 12.20.5.3 800 10
