TraceRoute Command | Paradyne 6301, 6341, 6342, 6371, 6351, 6302

6. Diagnostics and Troubleshooting

TraceRoute

The TraceRoute program is an IP diagnostic tool that allows you to learn the path a packet takes from the service domain local host to its remote host.

If you are unable to ping a device in a Hotwire network configuration, you may want to run a TraceRoute to identify the link (destinations up to 64 hops) between the router and the device that is not forwarding the Ping message.

Table 6-4. TraceRoute Command

traceroute dest-ip [-xsource-ip][-lbytes] [-wtime] [-hhops] [-i{ eth1 _dsl1 } ]

Minimum Access Level: Operator

Command Mode: Standard

Performs TraceRoute to the specified destination IP address. Once TraceRoute starts, the input prompt will not redisplay until TraceRoute finishes or is aborted with Ctrl-c.

Example: traceroute 135.300.41.8 –w 60 -i eth1

dest-ip– The destination IP address for TraceRoute.

source-ip– The source IP address used. The default source address is from the service domain in which the test is being done. The IP address is validated to verify that it is an interface IP address.

bytes – Bytes of data (l = length). The default is 64 bytes; the range is 0–15,000.

time – Time (in seconds) before the TraceRoute is abandoned. The default is 10 seconds; the range is 0–60.

hops – Decimal number that specifies the maximum number of hops to be tested. The default is 8; the range is 0–128.

interface – Specifies the target interface for the command. Do not use with the –xsource-ipselection.

eth1 – Ethernet interface

dsl1 – DSL interface
