1   Introduction

This instruction concerns alarm handling.

1.1   Alarm Description

The alarm is raised when the relevant Diameter connection is either administratively disabled by Operation and Maintenance (O&M) or disabled by a peer.

Note:  
The alarm is cleared automatically if one of the following alarms is raised:

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

1.2.3   Conditions

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

2   Procedure

This section describes the procedure to follow when this alarm is received.

2.1   Analyzing Alarm

Select action according to the alarm cause:

2.2   Actions for Link Disabled by Operation and Maintenance

Do the following:

  1. Navigate to DIA-CFG-NeighbourNode Managed Object (MO), 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. Is the alarm raised for a connection acting as responder?

    Yes: Proceed with Step 5.

    No: Continue with the next step.

  3. Navigate to the DIA-CFG-Conn MO:

    (DIA-CFG-NeighbourNode=node12.ericsson.com\23abc)>DIA-CFG-Conn=abc\23node12.ericsson.com\23conn1

  4. Proceed with Step 10.
  5. Enter Config mode:

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

  6. Set the responder to be an initiator:

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

    This is required because the responder must reinitiate the connection to delete the alarm on the other side.

  7. Commit the setting:

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

  8. Verify the setting:

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

    initiateConnection=true
  9. Navigate to the DIA-CFG-Conn MO:

    (DIA-CFG-NeighbourNode=node12.ericsson.com\23abc)>DIA-CFG-Conn=abc\23node12.ericsson.com\23conn1

  10. Enter Config mode:

    (DIA-CFG-Conn=abc\23node12.ericsson.com\23conn1)>configure

  11. Enable the connection:

    (config-DIA-CFG-Conn=abc\23node12.ericsson.com\23conn1)>enabled=true

  12. Commit the setting:

    (config-DIA-CFG-Conn=abc\23node12.ericsson.com\23conn1)>commit

  13. Verify the setting:

    (DIA-CFG-Conn=abc\23node12.ericsson.com\23conn1)>show enabled

    enabled=true
  14. Is the alarm raised for a connection action as responder?

    Yes: Continue with the next step.

    No: Proceed with Step 22.

  15. Check the link status:

    (DIA-CFG-Conn=abc\23node12.ericsson.com\23conn1)>show linkstatus

    The system returns Up if the connection is set up.

  16. Is the connection set up?

    Yes: Continue with the next step.

    No: Proceed with Step 22.

  17. Navigate to DIA-CFG-NeighbourNode MO:

    (DIA-CFG-Conn=abc\23node12.ericsson.com\23conn1)>up

  18. Enter Config mode:

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

  19. Reset the responder:

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

    It was set as initiator in Step 6.

  20. Commit the setting:

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

  21. Verify the setting:

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

    initiateConnection=false
  22. Is the alarm cleared?

    Yes: Proceed with Step 25.

    No: Continue with the next step.

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

2.3   Actions for Link Disabled by Peer

Do the following:

  1. Is the alarm raised for a connection acting as responder?

    Yes: Continue with the next step.

    No: Proceed with Step 3.

  2. Wait for the peer node to re-establish the connection and reception of a Capabilities-Exchange-Request (CER).
  3. Is attribute blockReason of the corresponding connection equal to DPR received, cause=DoNotWantToTalkToYou?

    Yes: Continue with the next step.

    No: Proceed with Step 11.

  4. Navigate to the DIA-CFG-Conn MO, 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,DIA-CFG-Conn=abc\23node12.ericsson.com\23conn1

  5. Enter Config mode:

    (DIA-CFG-Conn=abc\23node12.ericsson.com\23conn1)>configure

  6. Disable the connection:

    (config-DIA-CFG-Conn=abc\23node12.ericsson.com\23conn1)>enabled=false

  7. Commit the setting:

    (config-DIA-CFG-Conn=abc\23node12.ericsson.com\23conn1)>commit -s

    The value of attribute blockReason is automatically changed to Not blocked.

  8. Enable the connection:

    (config-DIA-CFG-Conn=abc\23node12.ericsson.com\23conn1)>enabled=true

  9. Commit the setting:

    (config-DIA-CFG-Conn=abc\23node12.ericsson.com\23conn1)>commit

  10. Verify the setting:

    (DIA-CFG-Conn=abc\23node12.ericsson.com\23conn1)>show enabled

    enabled=true
  11. Is the alarm raised for a connection acting as initiator?

    Yes: Continue with the next step.

    No: Proceed with Step 13.

  12. Wait for automatic reconnect and sending of CER.
  13. Is the alarm cleared?

    Yes: Proceed with Step 16.

    No: Continue with the next step.

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