Using ping and loopback Commands

Use the show diag command to view all the interface types installed in your system. Use the show diag slot command to view information about port adapters on a VIP2 that is installed in your system, as shown in the following example of a PA-4T+ on a VIP2 that is in interface processor slot 3:

For complete VIP2 command descriptions and examples, refer to the publications listed in the “Related Documentation” section on page vi. Proceed to the following section “Using ping and loopback Commands.”

The packet internet groper (ping) and loopback commands allow 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 these commands. After you verify that the system has booted successfully and is operational, you can use these commands to verify the status of interface ports. Refer to the publications listed in the “Related Documentation” section on page vi for detailed command descriptions and examples.

The ping command sends an echo request out to a remote device at an IP address that you specify. After sending a series of signals, the command waits a speciﬁed time for the remote device to echo the signals. Each returned signal is displayed as an exclamation point (!) on the console terminal; each signal that is not returned before the speciﬁed time-out 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.
