Diagnostics and Troubleshooting Overview

Several features are available to assist you in evaluating the Hotwire DSL Router.

The following sections are covered in this chapter:

Device Restart

Alarms Inquiry

System Log on page 6-2

Ping on page 6-5

TraceRoute on page6-7

Device Restart

The DSL router can be restarted locally or remotely. From the CLI, type Restart

and press Enter.

The router reinitializes itself, performing a power-on self-test and re setting the

local System Log (SYSLOG).

Alarms Inquiry

The DSL router’s front panel includes an Alarm (ALM) LED to alert yo u to alarm

conditions. The alarm(s) detected can be viewed using the show alarms CLI

command.

See show alarms on page A-24 in Appendix A, Command Line Interface, for

information about the command and what is displayed when the command is

entered.
