User Guidelines
• The traceroute command works by taking advantage of the error messages generated by a device when
a datagram exceeds its time-to-live (TTL) value.
• The traceroute command starts by sending probe datagrams with a TTL value of one. This causes the
first device to discard the probe datagram and send back an error message. The traceroute command
sends several probes at each TTL level and displays the round-trip time for each.
• The traceroute command sends out one probe at a time. Each outgoing packet may result in one or
two error messages. A "time exceeded" error message indicates that an intermediate device has seen
and discarded the probe. A "destination unreachable" error message indicates that the destination
node has received the probe and discarded it because it could not deliver the packet. If the timer goes
off before a response comes in, the traceroute command prints an asterisk (*).
• The traceroute command terminates when the destination responds, when the maximum TTL is
exceeded, or when the user interrupts the trace with Esc.
