Monitoring the DSU

What to Monitor

This chapter presents information on how to access and monitor DSU status and performance statistics on the DDS network. You can monitor DSU operations by viewing:

HLEDs on the ATI Status screen or the DSU's front panel

HUnit Status screen on the ATI

HHighest priority Health and Status message displays on the right on the last line of all screens.

HNetwork Interface Status screen on the ATI

HNetwork Performance Statistics screen on the ATI

HNMS via SNMP MIB objects

Refer to MIB Descriptions, Appendix C, for the SNMP MIBs supported by the

DSU.

DSU LEDs

The DSU LEDs can be viewed on the Display LEDs Status screen. This ATI status screen is available locally and remotely.

The 12 LEDs are organized in three groups:

HSystem LEDs display the status of the unit

HNetwork LEDs provide the status of the network interface

HPort LEDs display the activity on the user data (DTE) port
