User Guidelines
•
The hostname must be a fully qualified DNS name. A fully qualified DNS name has a period at the end.
• Press Esc to stop pinging.
• Following are examples of unsuccessful pinging:
– Destination does not respond. If the host does not respond, a “no answer from host” appears in ten
seconds.
– Destination unreachable. The gateway for this destination indicates that the destination is unreachable.
– Network or host unreachable. The device found no corresponding entry in the route table.
