Running Ping
To ping another device on the network from the switch, enter this command in normal executive and
privileged EXEC mode:
This example shows how to ping a remote host from normal executive mode:
Switch# ping labsparc
labsparc is alive
Switch> ping 72.16.10.3
12.16.10.3 is alive
Switch#
This example shows how to use a ping command in privileged EXEC mode to specify the number of
packets, the packet size, and the timeout period:
Switch# ping
Target IP Address []: 12.20.5.19
Number of Packets [5]: 10
Datagram Size [56]: 100
Timeout in seconds [2]: 10
Source IP Address [12.20.2.18]: 12.20.2.18
!!!!!!!!!!
----12.20.2.19 PING Statistics----
10 packets transmitted, 10 packets received, 0% packet loss

Understanding How IP Traceroute Works

The command output displays all network layer (Layer 3) devices, such as routers, that the traffic passes
through on the way to the destination.
Command Purpose
