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 TraceRoute to identify the link (destinations up to 64 hops) between the DSL router and the device that is not forwarding the Ping message.

traceroute dest-ip [-xsource-ip ] [-lbytes ] [-wtime ] [-hhops ] [-i{eth1 dsl1}]

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

Minimum access level: Administrator

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). Default = 64 bytes. Range = 0±15,000.

time ± Time (in seconds) before the TraceRoute is abandoned. Default = 10 seconds. Range = 0±60.

hops ± Decimal number that specifies the maximum number of hops to be tested. Default = 8. Range = 0±128.

interface ± The target interface for the command (eth1 dsl1). Do not use with the ±x source-ip selection.

Example: traceroute 135.300.41.8 ±w 80 -i eth1

The Hop # is the Time to Live (TTL) value set in the IP packet header. The Round Trip Time contains the time in 100ms intervals for each attempt to reach the destination with the TTL value.
