This chapter describes how to view and manage alarms and events in CDM. You can identify errors, alarms, or events that a Cisco DSLAM chassis generates. When an error occurs on a managed object in the network, CDM receives immediate notification.
You can detect the source of an alarm by using the Event Browser window, or Event Browser, to navigate through the network object hierarchy to the affected object. Alarms propagate up the element hierarchy according to severity. The Event Browser displays events that the system flags.
The Event Browser icon on the Launchpad is shown in Figure 7-1.
The Event Browser stores all alarms and displays current as well as historical data. You can detect the presence of an alarm by the color that Cisco EMF uses to represent network objects. The color of an object indicates its operational status. Simple Network Management Protocol (SNMP) traps raise alarms on CDM.
For further information on the Event Browser, refer to the Cisco Element Manager Framework User Guide.
The Event Browser window displays the following information in a table format:
The time and date when the system reports an event.
The name of the object that is affected by the event.
A description of the event and its level of severity.
You can navigate directly from a single event to the affected object to perform detailed configuration activities.
Steps for Viewing Events in the Event Browser
This section includes instructions for viewing events and alarms in the Event Browser window and includes the following topics:
Complete the following steps to set transit subscriber PVCs. To view events in the Event Browser window, follow these steps:
Step 1 Open the Event Browser window by using one of the following methods:
Right-click the object on the relevant chassis in the Map Viewer window.
Right-click the object on a map node.
Click the Events icon, shown in Figure 7-3, on the Cisco Element Manager Framework Launchpad window.
Note If the Event Browser window is hidden, choose Event Browser from the Window menu on the CDM
Map Viewer window to make it visible.
Figure 7-3 Events Icon
If you click the Events icon, you can view all alarms on all objects. Doing this opens the Query Editor window.
Figure 7-4 Query Editor Window
Step 2 Set your query criteria on the window.
The Query Editor contains many tabs that you can use to define and refine your alarm search criteria. You can use the >> or << arrows to move the available values to the right side of the tab to select them.
Step 3 Always click Activate after you specify the values for the alarms that you want to view.
The Event Browser displays all alarms that match your query criteria.
The Query Editor contains the following tabs:
Severity
Time
Event Status
Source Domain
Mgmt Domain
User
Event Class
Object Scope
Object Class
Object Attribute Presence
Object Attribute Value
Note For more detailed information about using the Query Editor, refer to the Cisco Element Management
Framework User Guide.
Viewing Specific Alarms or Events
To view a specific alarm on one object, follow these steps:
Step 1 From the Map Viewer window, right-click the object that generated the alarm.
Step 2 Choose Tools > Open Event Browser from the object menu.
Only the alarm for the object that you selected displays.
You can open the Query Editor from this window to modify your criteria.
Using the Full Event Description Window
You can get more specific information about events that display in the Event Browser window by opening the Full Event Description window, shown in Figure 7-5.
Figure 7-5 Full Event Description Window
The Full Event Description window fields are described in Table 7-1.
Table 7-1 Full Event Description Window Fields
Field
Description
Object name
Displays the name of the Cisco EMF managed object for the event.
Severity
Displays the severity of the reported event.
Time and Date
Displays the time and date that the system reports the event.
Event State
Indicates whether the event is active or cleared. When the event is cleared, the Clearing Method, User Responsible for Clearing, and Clearing Time and Date fields become active.
Management Domain
Indicates the management domain that is the source of the event.
Communication Domain
Indicates the communications domain that is the source of the event.
Event Description
Provides a summary description of the reported event.
Acknowledgement User
An operator who acknowledges the alarm can use this field to enter his or her name. When other operators view that alarm, they can see that this alarm has been acknowledged and by whom.
Acknowledgement Time and Date
An operator who acknowledges the alarm can use this field to enter the time and date of acknowledgement; when other users view that alarm, they can see when this alarm was acknowledged.
Acknowledgement Comment
An operator who acknowledges the alarm can use this field to enter any comments; other users can see any comments about this alarm.
Clearing Method
Identifies when the network or user cleared the event.
User Responsible for Clearing
Displays the user name responsible for clearing the event.
Clearing Time and Date
Indicates the time and date the event was cleared.
Clearing Reason
Identifies the information that was entered in the Events Clearing window, which is completed when the Clear indicator is selected.
To open the Full Event Description window, follow these steps:
Step 1 In the Event Browser window, right-click the event whose details you want to view to open the object menu.
Step 2 Choose Event Information > Event Information dialog from the object menu.
If the event is not cleared, the Event State field displays Active and the other fields are dimmed.
You cannot modify the displayed information.
Step 3 When the system has cleared an event, you can view the method used to clear it by clicking Clearing Event.
Step 4 Click Close to exit the Full Event Description window.
Step 5 Click Close to exit the Event Browser window.
Using the Cisco EMF Event Manager
Additionally, you can use the Cisco EMF Event Manager to complement CDM. This optional application enables you to set thresholds and monitor any supported CDM management information database (MIB) variable (that is, those variables that appear on the CDM windows).
Determining Alarm Severity
The associated colors that indicate alarm severity are described in Table 7-2.

Identifying Alarms
Potential alarms that CDM reports against specific managed objects in a DSLAM chassis are described in this section. The alarms are categorized by module type and are organized within tables. The alarm tables list the alarms sequentially by ID number, then give the definition (alarm parameter), the level of severity, and a description of the event that caused the alarm. These tables can be useful for troubleshooting DSLAM chassis management.
Note Refer to the Cisco 6100 Series with NI-1 Alarm Summary Guide for more information on events and
alarms that are specific to the Cisco 6100 Series system DSLAM chassis hardware.
Alarms that are specific to ATU-C modules are described in Table 7-3.
