Using Ping
Executing Ping
If you attempt to ping a host in a different IP subnetwork, you must define a static route to the network 
or have IP routing configured to route between those subnets. For more information, see 
IP routing is disabled by default on all switches. If you need to enable or configure IP routing, see 
Beginning in privileged EXEC mode, use this command to ping another device on the network from the 
switch:
Note
Though other protocol keywords are available with the ping command, they are not supported in this 
release.
This example shows how to ping an IP host:
Switch# ping 172.20.52.3
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echoes to 172.20.52.3, timeout is 2 seconds:

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms
Switch#

To end a ping session, enter the escape sequence (Ctrl-^ X by default). Simultaneously press and release 
the CtrlShift, and 6 keys and then press the X key.
