7 Configure Northbound Interface Traps

You can specify northbound interface (destination) fault trap receivers for northbound systems, such as a network management system, to receive forwarded SNMP trap fault notifications in either OCSDM format or International Telecommunication Union (ITU) X.733 format. You can also configure the heartbeat trap for the northbound interface, which is discussed later in this chapter.

The OCSDM fault manager function forwards trap notifications over the northbound interface to the configured trap receiver system(s).

When you install a standalone OCSDM server or an OCSDM cluster, you must configure the global identifier (ID). When devices that are managed by SDM send SNMP traps, the global ID is embedded in the trap. When an administrator views the trap on their northbound system, the originating device can be determined by viewing global ID contained in the trap. See the Specify the Global ID for Northbound Trap Receivers section in the Typical Installation chapter of the Oracle Communications Session Delivery Manager Installation Guide for more information.

Note:

The global ID must be the same for all nodes in the same OCSDM cluster. If there is more than one cluster in a network, each cluster must use a different global ID.

In the following diagram, devices send all traps to the OCSDM server, which sorts them into events and alarms. Events are the aggregated list of all such messages while alarms record only the current state or latest event.
