What to Monitor

This chapter presents information on how to access and monitor the Hotwire DSL Router's status and performance statistics. You can monitor DSL router operations by viewing:

HLEDs on the DSL router's front panel.

HDSL Router Interfaces Status, including DSL and Ethernet LED status.

HDSL Router Statistics, including DSL Service Domain, DSL Management Domain, Ethernet, and IP statistics.

HDSL Router SNMP traps.

Detecting Problems

The DSL router can detect and report problem conditions and the user can perform diagnostic tests. The DSL router offers a number of indicators to alert you to possible problems:

HLEDs provide status. Refer to Status LEDs in the Hotwire DSL Router Installation Instructions for LED indications and troubleshooting of the hardware installation.

HStatus messages for both the Ethernet and DSL links. Refer to Status of Interfaces on page 5-2.

HNetwork performance statistics for both the Ethernet and DSL links. Refer to Interface Statistics on page 5-3.

HCurrent status of DSL Router SNMP traps, if enabled. Refer to Appendix C, Traps & MIBs.

For additional information regarding diagnostic tests, System Log messages, and troubleshooting, refer to Chapter 6, Diagnostics and Troubleshooting.
