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 Chapter 38, “Configuring IP Unicast Routing.”

IP routing is disabled by default on all switches. If you need to enable or configure IP routing, see Chapter 38, “Configuring IP Unicast Routing.”

Beginning in privileged EXEC mode, use this command to ping another device on the network from the switch:

Command	Purpose
ping ip host address	Ping a remote host through IP or by supplying the hostname or
	network address.

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#

Table 45-1describes the possible ping character output.

Table 45-1	Ping Output Display Characters
