1   Introduction

This instruction concerns alarm handling.

1.1   Alarm Description

The alarm is raised when a Diameter peer node has been disabled, either administratively or by the system because of a fault.

The possible alarm causes and fault locations are explained in Table 1.

Table 1    Alarm Causes

Alarm Cause	Description	Fault Reason	Fault Location	Impact
Diameter peer node disabled	The Diameter peer node has been disabled	Diameter peer node disabled	Not applicable	The communication with the peer node is lost

The alarm attributes are listed and explained in Table 2.

1.2   Prerequisites

This section provides information on the documents, tools, and conditions that apply to the procedure.

1.2.1   Documents

This instruction references the following documents:

• Data Collection Guideline
• vDicos, Diameter Own Node Disabled

1.2.2   Tools

No tools are required.

1.2.3   Conditions

Before starting this procedure, ensure that the following conditions are met:

• A vDicos, Diameter Peer Node Disabled alarm is raised.
• System authorization and authentication have passed successfully.
• Diameter configuration data is correctly defined.
• An Ericsson Command-Line Interface (ECLI) session in Exec mode is in progress.

2   Procedure

The alarm is cleared automatically when alarm vDicos, Diameter Own Node Disabled is raised. Alarms for peer nodes related to the own node are cleared and a new alarm is raised for the own node.

Do the following:

1. Navigate to the DIA-CFG-NeighbourNode managed object, for example:

   >dn ManagedElement=NODE06ST,XyzFunction=xyz,DIA-CFG-Application=DIA,DIA-CFG-StackContainer=abc,DIA-CFG-PeerNodeContainer=abc,DIA-CFG-NeighbourNode=node12.ericsson.com\23abc

2. Enter Config mode:

   (DIA-CFG-NeighbourNode=node12.ericsson.com\23abc)>configure

3. Enable the peer node:

   (config-DIA-CFG-NeighbourNode=node12.ericsson.com\23abc)>enabled=true

4. Commit the setting:

   (config-DIA-CFG-NeighbourNode=node12.ericsson.com\23abc)>commit

5. Verify the setting:

   (DIA-CFG-NeighbourNode=node12.ericsson.com\23abc)>show enabled

   enabled=true

6. Is the alarm cleared?

   Yes: Proceed with Step 9.

   No: Continue with the next step.

7. Perform data collection, refer to Data Collection Guideline.
8. Consult the next level of maintenance support. Further actions are outside the scope of this instruction.
9. Job is completed.
