Using CDM Fault Management

This chapter describes the Fault Management system on the Cisco Digital Subscriber Line Manager (CDM), which you use to view alarms generated by the physical entities containing the chassis, slots, modules and ports. The agent sends notifications, which are recognized by Cisco EMF, and alarms are raised on the objects. Tables list the alarms associated with objects.

To view the objects that propagated the alarm, select the Severity On option from the Severity menu.

The full event description window provides a more in-depth description of the alarm, refer to the Cisco Element Management Framework User Guide for more information.

Viewing a Generated Fault

An alarm generates a fault. To view a fault:

Step 1 Click the icon of the object that generated the alarm to highlight it.

Step 2 Right-click the object icon and select AV Tools --\> Open Event Browser from the pop-up menu. The Event Browser window appears (Figure 9-1).

Figure 9-1: Sample Event Browser Window

The Event Browser window contains the following information:

Object Name

Displays the name of the object/physical entity that generated the alarm.

Time

Displays the system time when the alarm was generated.

Severity

Each alarm type defined by a vendor type employed by the system has an associated severity. This object specifies the severity of the alarm generated.

A colored square appears to the left of the Object Name. The color of the square depends on the severity of the alarm.

critical (red)---An alarm used to indicate a severe, service-affecting condition has occurred and that immediate corrective action is imperative, regardless of the time of day or day of the week.
major (orange)---An alarm used for hardware or software conditions that indicate a serious disruption of service or the malfunctioning or failure of important hardware. These problems require the immediate attention and response of a technician to restore or maintain system capability. The urgency is less than in critical situations because of a lesser immediate or impending effect on service or system performance.
minor (yellow)---An alarm used for conditions that do not have a serious effect on service to customers or for conditions in hardware that are not essential to the operation of the system.
info (white)---An alarm used to raise attention to an impending condition that can not be classified as a problem.
preprovision (dark green)---That part of the network setup before the service is actually provisioned.

Description

Displays the description that is associated with the alarm (Table 9-1).

Table 9-1: Alarm Severity and Descriptions

Equipment with which Alarm is Associated Severity Alarm Description

ADSL Line

Minor (yellow)

ATU-C port failure

Upstream Rate not above Min_rate

Downstream Rate not above Min_rate

The modem is reporting a near end LOS, LOF, or LOCD or a far end LPR failure (This only occurs if the line is enabled to alarm on failures)

DMT Card

Major (orange)

Card missing from a provisioned slot

A module has been detected but it is not communicating with the system control processor (>R1)

Minor (yellow)

A module was inserted in the slot that did not match the type that was pre-provisioned for the slot

A module is detected in this slot but it is not a valid module for this slot or is invalid for the system configuration

Module reset unexpectedly

Info (white)

Module was detected (module software was loaded)

NI-2

Major (orange)

Loss of timing reference

Various buffer overflows (>R1)

Chassis

Major (orange)

An over temperature conditions has been detected. This is measured on the NI-2 card

Multiple fans have failed (The power module forces the fan to full speed upon seeing one or more fan faults. This occurs independent of the software.)

One or both of the fan trays have been removed or are missing

The two power units installed are not compatible (>R1)

The input voltage to one or both of the power modules is outside of its acceptable range

The current through one or both of the power modules is excessive.

The fan output voltage from one or both of the power modules is outside of its acceptable range

One or both of the power units are reporting a fault condition. The fault is either over temp, output failure or input failure.

The power supply is over its temperature limit

Minor (yellow)

A single fan has failed (The power module forces the fan to full speed upon seeing one or more fan faults. This occurs independent of the software.)

The power module is not detected by the NI-2. This only occurs if the Power Module is provisioned (>R1)

The power module installed does not match the provisioned type (>R1)

TBD

An alarm has been detected on the station alarm 1 input (>R1)

An alarm has been detected on the station alarm 2input (>R1)

An alarm has been detected on the station alarm 3 input (>R1)

NA

The circuit breaker on the power module has tripped due to an over-current fault (This condition triggers a separate (from critical/major/minor) relay contact closure. It is not signaled through any other means (no SNMP or LED indicators).)

OC-3 Port

Minor (yellow)

SONET: Incorrect Payload type Signal Label Mismatch

Critical (red)

SONET: Loss of Cell Delineation

SONET: Path RDI received. This is equivalent to Path FERF

SONET: Path AIS received

SONET: Loss of Pointer condition

SONET: Line RDI received. This is equivalent to Line FERF

SONET: Line AIS received

SONET: Loss of Frame condition

SONET: Loss of Signal detected by SONET device

The OC-3 (if this is a OC-3 module) or STM1 (if this is an STM1 module) port has failed (>R1)
