Syntax
traceroute ip-address |hostnme [size packet_size] [ttl max-ttl] [count packet_count] [timeout time_out] [source ip-address]
[tos tos]
ƒ ip-address — IP address of the destination host. An out-of-band IP address can be specified as described in the usage
guidelines. (Range: 1 - 160 characters)
ƒ hostname — Hostname of the destination host (Range: Valid IP Address)
ƒ size packet_size — Number of bytes in a packet. (Range: 40-1500)
ƒ ttl max-ttl—The largest TTL value that can be used. The traceroute command terminates when the destination is
reached or when this value is reached. (Range:1-255)
ƒ count packet_count — The number of probes to be sent at each TTL level. (Range:1-10)
ƒ timeout time_out — The number of seconds to wait for a response to a probe packet. (Range:1-60)
ƒ source ip-address — One of the interface addresses of the device to use as a source address for the probes. The
device will normally pick what it feels is the best source address to use. (Range: Valid IP Address)
ƒ tos tos — The Type-Of-Service byte in the IP Header of the packet. (Range: 0-255)
Default Configuration
size packet_size — The default is 40 bytes.
ttl max-ttl — The default is 30.
count packet_count — The default count is 3.
timeout time_out — The default is 3 seconds.
Command Mode
User EXEC mode
User Guidelines
The traceroute command works by taking advantage of the error messages generated by routers 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 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 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 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.
To find the trace to an out-of-band IP address, use the out-of-band IP address format: oob/ip-address.
