Manage Fault Notification on the Northbound Interface

Synchronize Alarms for a Northbound Fault Trap Receiver

A specified time period can be configured to synchronize northbound interface alarm fault trap notifications from devices that are managed by SDM to determine the health of devices.

When the alarm synchronization feature is configured for a specified time interval and enabled, traps are resent from devices to the northbound interface. The system administrator determines which traps are new and which are duplicates. A system administrator uses this feature to ensure that device alarm fault trap notifications received on their northbound systems are current with the alarm trap notification generated by the device or in situations when previous traps are lost on SDM or the northbound system and need to be regained from the device.

Note:

The Start time fields default to 24 hours prior to the current time and the End time fields default to the current time.

1. From the menu bar, select Settings, Faults, Trap receivers.
2. In the Trap receivers configuration table, select a trap receiver and click Sync.
3. In the Trap receiver alarm synchronization dialog box, complete the following fields:

   Synchronization from	Select from the following options: Click the Event radio button to synchronize the aggregated list of all trap messages. Click the Alarm radio button to select the current device state or latest event trap messages.
   Minimum severity level	Select from the following ITU X.733 alarm severity levels: Indeterminate (Unknown)—Clear all events and synchronize from when they were cleared. Critical (Emergency)—Send critical events or alarms. Major—Send major and critical events or alarms. Minor—Send minor, major, and critical events or alarms. Warning—Send warning, minor, major, and critical events or alarms.
   Start time field	To specify the start date, enter the month, day, and year (mm/dd/yyyy) or click the calendar icon to select the date and enter the time in the hour, minute, and second format (hh:mm:ss).
   End time field	To specify the end date, enter the month, day, and year (mm/dd/yyyy) or click the calendar icon to select the date and enter the time in the hour, minute, and second format (hh:mm:ss).

4. Click OK.
5. In the confirmation dialog box, a message displays indicating the total number of events or alarms to be synchronized based on the parameters that you configured in this task. Click Yes to synchronize them.

Edit a Northbound Fault Trap Receiver

1. From the menu bar, select Settings, Faults, Trap receivers.
2. In the Trap receivers configuration table, click Edit.
3. In the Edit trap receiver dialog box, you can edit the following fields for the Destination configuration:

   IP address	The IP address of the northbound trap receiver.
   UDP port	The default user datagram protocol (UDP) port is 162.
   Community string	The SNMP community name.
   SNMP version drop-down list	The northbound trap receiver accepts SNMP version V2 only.
   Forward enabled check box	Check the check box to enable trap forwarding on this northbound trap receiver. Uncheck the check box to disable forwarding.

4. Edit the following fields for the Filter configuration:

   Severity level drop-down list	Select from the following ITU X.733 alarms: Indeterminate (Unknown). Critical (Emergency)—The alert indicates that action must be taken immediately. If no actions are taken, there may be physical, permanent, and irreparable damage to your system. The default color code is red. Major—Critical conditions exist. The functionality has been seriously compromised and a loss of functionality, hanging applications, and dropped packets may occur. If no actions are taken, your system suffers no physical harm, but ceases to function. The default color code is salmon. Minor—Error conditions exist. The functionality has been impaired to a certain degree and you might experience compromised functionality. There is no physical harm to your system, but you need to take actions to keep your system operating properly. The default color code is orange. Warning—Warning conditions exist. Some irregularities in performance. These conditions are noteworthy and you should take actions to keep your system operating properly. The default color code is light yellow. An alarm is forwarded if it is equal to the selected alarm or has a higher severity than the selected alarm.
   Format field	Select from the following northbound trap formatting options: Click the OC SDM radio button to forward traps from the SDM server to the northbound trap receiver in their originating format. Click the ITU X.733 radio button to convert traps from session delivery product devices to the northbound trap receiver in an ITU X.733 format.
   OC SDM traps check box	Check the check box to enable all traps generated by the SDM server to be forwarded to this trap receiver.
   Device traps check box	Check the check box to enable all traps generated by managed devices to be forwarded to this trap receiver.

5. You can edit the following options to specify the destination of traps:
   • Select the All devices radio button to send traps to all devices. If you select this option, you are finished.
   • Select the Select devices radio button to send traps to select devices. If you select this option, proceed to the next steps.
6. If you need to add a device to the Mangaged devices table, expand the hierarchical group folder and navigate to the network function (NF) device you want as a trap source.
7. Select the device and click Add.
   The NF device appears in the Selected trap source devices table.
8. Repeat the previous two steps to add more devices.

   Note:

   A maximum of 10 trap receivers can be configured at once, regardless of the format.
9. If you need to remove a device to the Selected trap source devices table, expand the hierarchical group folder and navigate to the network function (NF) device you want as a trap source.
10. Select the device and click Remove.
    The NF device appears in the Mangaged devices table.
11. Repeat the previous two steps to remove more devices.
12. Click OK.
    The trap receiver appears in the Trap receivers configuration table.

View Northbound Fault Trap Receivers

1. From the menu bar, select Settings, Faults, Trap receivers.
2. In the Trap receivers configuration table, view the following trap receiver column information:

   IP address	The northbound trap receiver IP address.
   UDP port	The default user datagram protocol (UDP) port is 162. UDP is used for establishing low-latency and loss tolerating connections. Change the default UDP port if you are using a different port for UDP connections.
   SNMP version	The trap receiver SNMP version, which can be version 2 (V2) only.
   Community string	The SNMP community name.
   Forward enabled	Indicates whether the trap receiver is enabled (True) or disabled (False).
   Status	The following trap receiver status conditions are possible: Enabled Disabled Suspended Syncing SyncSucceed SyncFailed
   Format	(Hidden) Indicates if a trap receiver is either in NNC (SDM server) format, or ITU for ITU X.733 format. If the trap receiver uses the ITU X.733 format, the SDM fault manager converts traps from its host(s) to the ITU X.733 format.
   Severity	(Hidden) The alarms that have a severity level that affects service are forwarded.
   Object ID	(Hidden) The internal SDM element object ID number.
