User Guidelines
The traceroute command takes advantage of the error messages generated by a router when a
datagram exceeds its time-to-live (TTL) value.
The traceroute user EXEC command starts by sending probe datagrams with a TTL value of
one. This causes the first router 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 user EXEC 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 router has seen and discarded the probe. A "destination unreachable" error
message indicates that the destination router 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
user EXEC command prints an asterisk (*).
The traceroute user EXEC command terminates when the destination responds, when the
maximum TTL is exceeded, or when the user interrupts the trace with Esc.
If you want to find the trace to an out-of-band address, use the out-of-band IP address format
oob/ip-address.
