User Guidelines
This command works by taking advantage of the error messages generated by switches when a
datagram exceeds its time-to-live (TTL) value. The
traceroute command terminates when
the destination responds when the maximum TTL is exceeded.
Examples
The following example discovers the routes that packets will actually take when traveling to
the destination specified in the command.
