Tracing Ip Addresses; Performing A Trace Route - 3Com SUPERSTACK 3 WEBCACHE 3000 User Manual

Tracing IP
Addresses
Performing a Trace
Route
You can interrupt a PING request at any time by clicking Stop.
Some network environments block PING traffic on the network. The PING
request may therefore fail even if the network device is operating
normally.
The Trace Route feature allows you to display the network hops from the
Webcache to a device on an IP network. This feature is useful to diagnose
connectivity problems such as a failed network device between the
Webcache and the web server being accessed.
To perform a trace route to a device using the Web interface:
1 Log in to the Web interface.
2 Click Device on the Toolbar.
3 Select Protocol > Ping/TraceRoute in the Navigation Tree. The
Ping/Traceroute screen is displayed.
4 In the IP Address/DNS Name field, enter the IP address or Domain Name
Server name of the device that you want to trace. Click TraceRoute.
5 The Webcache sends a trace route request to the specified device and a
message similar to the following is displayed:
traceroute to 192.168.1.254, 30 hops max, 38 byte packets
If the device is accessible and functioning correctly, a message similar to
the following is displayed which displays the network hops. Each hop
may take a few seconds to complete:
1.router1 (192.168.1.255) 1.292ms, 1.343ms, 1.810ms
2.router2 (192.168.1.256) 26.027ms, 27.156ms, 44.902ms
3.router3 (192.168.1.257) 24.323ms, 24.854ms, 30.096ms
4.router4 (192.168.1.258) 27.303ms, 33.639ms
If the device is not accessible, or is not functioning correctly, only the hops
that worked are displayed.
Trace Route Symbols
A symbol may be displayed after a network hop which provides further
information about that hop. For further information, see the
