2. Click either the Destination IP Address or Dest Hostname
radio button, and then type the appropriate data in the

3. In the Config Data section, change any of the following
parameters, as needed:
Field Description
Probe Message
Type
The traceroute can use ping/UDP messages
to conduct the traceroute. Some routers in
the path may not support one or the other
method. Try one, and if not working, try the
other.
No. of Probes per
TTL
The number of redundant packets that will be
sent in each transmission (to account for
packets dropped due to connection or server
problems).
Maximum hops
The maximum number of hops that can be
discovered in a traceroute before it
terminates.
Traceroute Timeout
(secs)
The number of seconds after sending
ping/UDP packets that the traceroute will
timeout if no reply is received.
Destination UDP port
When the Probe Message Type is specified
as UDP, the traceroute commands includes
an invalid destination UDP port address in
the UDP packets. When a packet reaches
the destination, it is dropped and the
computer replies with an error message. This
error message is used to identify the
completion of the traceroute.
This field specifies the invalid UDP port
number to use. This field is not used if the
Probe Message Type is ping.
4. Click to begin the trace.
The results display in the window at the bottom of the page and
include the IP address of each router or computer reached,
from the first to last hop, and the access time for each packet
sent.
