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.

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.

   SNMP version drop-down list	You cannot change the SNMP version once the trap receiver is configured.
   Community string	The SNMP community name. This fiels is relevant only for SNMPv2 version.
   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 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. Possile values could be: 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. 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 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 ITU 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. You can edit the following options to specify the destination of traps:
   • Select the All devices radio button to send traps from all devices to Northbound Trap Receiver. This means that traps from all devices are sent 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. 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.
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. You can add a maximum of 10 trap receivers to the Trap Receivers Configuration table.

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. It can be v2 or v3.
   Community string	The SNMP community name. This field shows data only for SNMPv2 version.
   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
   SNMPv3 username	The SNMPv3 username. This field shows data only for SNMPv3 version
   SNMPv3 Authentication Protocol	The SNMPv3 authentication protocol assigned to the trap receiver.
   SNMPv3 Privacy Protocol	The SNMPv3 privacy protocol assigned to the trap receiver.
   Format	(This is hidden by default.) 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 OCSDM fault manager converts traps from its host(s) to the ITU X.733 format.
   Severity	(This is hidden by default.) The alarms that have a severity level that affects service are forwarded.
   Object ID	(This is hidden by default.) The internal OCSDM element object ID number.

1. From the menu bar, select Settings, Faults, Trap receivers.
2. In the Trap receivers configuration table, select a network function (NF) device trap receiver and click Delete.
3. In the Success dialog box, click OK.
