4.3.16.4 TraceRoute
Use the TraceRoute page to determine the layer 3 path a packet takes from the
device to a specific IP address or hostname. When you initiate the TraceRoute com-
mand by clicking the Start button, the device sends a series of TraceRoute probes
toward the destination. The results list the IP address of each layer 3 device a probe
passes through until it reaches its destination - or fails to reach its destination and is
discarded. The information you enter on this page is not saved as part of the device
configuration.
To access this page, click System > Utilities > TraceRoute.

Description
The DNS-resolvable hostname or IP address of the system to attempt
to reach.
TraceRoute works by sending UDP packets with increasing Time-To-
Live (TTL) values. Specify the number of probes sent with each TTL.
The maximum Time-To-Live (TTL). The TraceRoute terminates after
sending probes that can be layer 3 forwarded this number of times. If
the destination is further away, the TraceRoute will not reach it.
The initial Time-To-Live (TTL). This value controls the maximum num-
ber of layer 3 hops that the first set of probes may travel.
The number of consecutive failures that terminate the TraceRoute. If
the device fails to receive a response for this number of consecutive
probes, the TraceRoute terminates.
The number of Seconds to wait between sending probes.
The UDP destination port number to be used in probe packets. The
port number should be a port that the target host is not listening on, so
that when the probe reaches the destination, it responds with an
ICMP Port Unreachable message.
The size of probe payload in bytes.
Select None, IP Address, Interface, or Loopback as a source. Each
option enables the respective menu item: IP Address, Interface, or
Interface Loopback, allowing the entry of the related information.
Enabled if IP Address option is selected from Source setting.
Enabled if Interface option is selected from Source setting.
Enabled if Loopback option is selected from Source setting.
