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

Understanding How IP Traceroute Works
IP traceroute allows you to identify the path that packets take through the network on a hop-by-hop basis.
