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 OCSDM 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 OCSDM 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.

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).
- Click OK.
- 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
- From the menu bar, select Settings, Faults, Trap receivers.
- In the Trap receivers configuration table, click Edit.
- 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. 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
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. - 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. - 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.
- 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.
- Select the device
and click
Add.
The NF device appears in the Selected trap source devices table.
- Repeat the previous two steps to add more devices.
- 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.
- Select the device
and click
Remove.
The NF device appears in the Mangaged devices table.
- Repeat the previous two steps to remove more devices.
- 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.
View Northbound Fault Trap Receivers
- From the menu bar, select Settings, Faults, Trap receivers.
- 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 OCSDM 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 OCSDM element object ID number.
