Using the ping Command

Proceed to the next section “Using the ping Command” to verify that each interface port is

functioning properly.

Using the ping Command

The ping command allows you to verify that an interface port is functioning properly and to check

the path between a speciﬁc port and connected devices at various locations on the network. This

section provides brief descriptions of the ping command. After you verify that the system has booted

successfully and is operational, you can use this command to verify the status of interface ports.

Refer to the documentation resources listed in the “Related Documentation” section on page vi for

detailed command descriptions and examples.

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 command 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 that the connection failed.

Following is an example of a successful ping command to a remote server with the address

10.10.10.10:

Router# ping 10.10.10.10

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echoes to 10.10.10.10, 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.

This completes the PA-H interface installation and conﬁguration.
