Using the Trace Route Tool
The Gateway provides a trace route tool for conducting the trace route with the default
Gateway, across the RF interface, or across the WAN interface. This tool provides a
supplemental role to the ping tool. While the ping tool confirms IP network reachability, you
cannot pinpoint and improve some isolated problems.
Consider the following situations:
y
When there are many hops (for example, gateways or routes) between the Gateway and
the destination, and there is a problem somewhere along the path. The destination
system may have a problem, but you need to know where a packet is actually lost.
y
The ping tools do not tell you the reasons for a lost packet.
The trace route tool can tell you where the packet is located and why the route is lost. Using
this tool, you can map a network path in real time from the Gateway to a local or public host.
To perform trace route activities, use the following procedure under
Trace Route
on the
Diagnostics menu.
1. In the
Trace Route
field, enter the IP address or domain name of a target host.
2. Click the
tracert
button. The trace route results appear in the Diagnostics – Trace Route
Results screen, as the Gateway sends UDP packets to each device between the Gateway
and the destination (see Figure 52). It starts with the nearest device and expands the
search by one hop until the destination is reached or the trace route times out. The results
screen may flash as the contents refresh during the trace route operation.
3. To close the screen, click the
Back
button.
