Configure Fault Notification on the Northbound Interface

Add a Northbound Fault Trap Receiver

To add a trap receiver, such as a network management system, that is connected to the northbound interface that receives fault notifications through the OCSDM server fault manager:

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

   IP address	The IP address of the northbound trap receiver that is receiving traps.
   UDP port	The trap receiver UDP port number. The default user datagram protocol (UDP) port is 162.
   SNMP version drop-down list	Northbound interfaces support both SNMPV2 and SNMPV3 versions. Once configured, you cannot change the SNMP version. Select the required SNMP version. Click Load to load the fields relevant to the SNMP version you selected. SNMPv2 is the default value. Hence, all V2 parameters are populated by default.
   Community string	The SNMP community name to which the trap receiver belongs. The default value is public. Note: This field relevant only for SNMP V2.
   SNMPv3 Username	Enter the user name. For more information on security levels, see Configuring Security Levels for Trap Receivers. Note: This field is visible only if you select SNMPv3.
   SNMPv3 Authentication Protocol	Click to select any one authentication protocol: SHA256 SHA126 None or . The default value is NONE. For more information on security levels, see Configuring Security Levels for Trap Receivers. Note: This field is visible only if you select SNMPv3.
   SNMPv3 authentication password	Provide a password. For more information on security levels, see Configuring Security Levels for Trap Receivers. Note: This field is visible only if you select SNMPv3.
   SNMPv3 Privacy Protocol	Select the Privacy Protocol. Possible values are: AES128 None
   SNMPv3 privacy password	Provide a privacy password. For more information on security levels, see Configuring Security Levels for Trap Receivers. Note: This field is visible only if you select SNMPv3.
   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. Complete the following fields for the Filter configuration:

   Severity level drop-down list	Select a severity level from the following ITU X.733 alarms: Indeterminate (Unknown)—The trap severity cannot be determined because of the nature of the information contained in the trap. 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. 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. 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. Warning—Warning conditions exist and there are some irregularities in performance. These conditions are noteworthy and you should take actions to keep your system operating properly. 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 OCSDM 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 International Telecommunication Union Alarm Model format defined in recommendation X.733 format.
   OC SDM traps check box	Check the check box to enable all traps generated by the OCSDM 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. Choose from the following options to specify the destination of traps:
   • Select the All devices radio button. to send traps from all devices to the Northbound trap receiver.
   • Select the Select devices radio button to forward traps from the selected device to the Northbound trap receiver. If you select this option, proceed to the next steps.
6. In 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.
9. Click OK.
10. Hover the mouse pointer on any column header to add or delete columns from being displayed.
    The trap receiver appears in the Trap receivers configuration table. You can add a maximum of 10 trap receivers to the Trap Receivers Configuration table.
