Using the ping Command to Verify Network Connectivity

Using the ping command, you can verify that an interface port is functioning properly. This section
provides a brief description of this command. Refer to the publications listed in the
Documentation" section on page viii
The ping command sends echo request packets out to a remote device at an IP address that you specify.
After sending an echo request, the system waits a specified time for the remote device to reply. Each
echo reply is displayed as an exclamation point (!) on the console terminal; each request that is not
returned before the specified timeout is displayed as a period (.). A series of exclamation points (!!!!!)
indicates a good connection; a series of periods (.....) or the messages [timed out] or [failed] indicate a
bad connection.
Following is an example of a successful ping command to a remote server with the address 10.0.0.10:
Router# ping 10.0.0.10 <Return>
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echoes to 10.0.0.10, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms
Router#
If the connection fails, verify that you have the correct IP address for the destination and that the device
is active (powered on), and repeat the ping command.
