3.9.12 Input Parameters
3.9.14 Test Results
Below the test control buttons is a text area that displays the results of the Traceroute test. Any
issues with the parameters will be displayed at the top of the results box. During a test, the Web
page will automatically refresh to show the current results. This refresh stops once the test is
completed.
The results area permits the user to select results and copy them for pasting into another
program. This is accessed by standard Web browser methods; either left-clicking in the box and
pressing Ctrl-A (select all), or right-clicking in the box and clicking “Select All”, or by simply using
the mouse cursor, and selecting those lines of interest. Copy is done via standard commands
used on the system in use (e.g., under Windows, use Ctrl-C to copy)
3.9.13 Controlling The Traceroute Test
The Traceroute Test is controlled by the following buttons.
Table 3-8, Input Parameters for the Traceroute Command
Table 3-9, Control Buttons on Traceroute Screen
Input Parameters Descriptions
Target IP address or Name
Either a standard IPv4 dotted-quad address is entered, or a host name. The address
entered will be unconditionally given to the DNS resolver; a dotted-quad will be
resolved to the same value, and a name will be resolved to its IPv4 address. The
final IPv4 address to be Tracerouted is shown in parentheses beside the host field.
Traceroute from what Source
There is a maximum of 3 choices, and these choices depend on what is available in
the unit.
a. Cable Modem. Always available
b. CPE. Available if the CPE stack is activated
c. EMTA. Available if the VoIP stack is licensed and activated
Max Hops
Range 1 to 255; default is 30. Also known as Max TTL, which is Maximum Time-To-
Live.
Traceroute Size
Range 0 to 1518. 0 is the standard size, resulting in packets of 40 bytes (inclusive of
all overhead).
Port Port to use. Standard is 33434 as the initial port.
Button Description
Start Test
Starts the Traceroute test. Each of the values provided in the input fields is evaluated for validity.
If the host name field is blank, the test will not proceed. (The exception is leaving it blank when a previous
name had been entered, in which case that name will be used).
Range checking is applied to the parameters. Any parameter out of range will be ignored, and the default
value used.
Any issues with the parameters will be displayed at the top of the results box.
When the test is started, the Web page will begin to automatically refresh. Also, a message will be
displayed:
Traceroute in use from <source>; max TTL xxx; size yyy; port nnnnn
indicating the parameters actually in use. This message is also in the text box.
Abort Test Stops any traceroute test currently in progress.
Clear Results Clears the results window.
