This command shows the route packets take to the specified destination.

traceroute host

host - IP address or alias of the host.

Privileged Exec

Use the traceroute command to determine the path taken to reach a

specified destination.

A trace terminates when the destination responds, when the maximum

timeout (TTL) is exceeded, or the maximum number of hops is

The traceroute command first sends probe datagrams with the TTL

value set at one. This causes the first router to discard the datagram

and return an error message. The trace function then sends several

probe messages at each subsequent TTL level and displays the round-

trip time for each message. Not all devices respond correctly to probes

by returning an "ICMP port unreachable" message. If the timer goes off

before a response is returned, the trace function prints a series of

asterisks and the "Request Timed Out" message. A long sequence of

these messages, terminating only when the maximum timeout has

been reached, may indicate this problem with the target device.

If the target device does not respond or other errors are detected, the

switch will indicate this by one of the following messages:

* - No Response

H - Host Unreachable

N - Network Unreachable

P - Protocol Unreachable
