A single word	`cat`	Topics that contain the word "cat". You will also find its grammatical variations, such as "cats".
A phrase. You can specify that the search results contain a specific phrase.	`"cat food"` (quotation marks)	Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase.

Troubleshooting the NNMi Northbound Interface

If the NNMi northbound interface is not working as expected, follow these steps until you have resolved the problem:

Verify that the trap destination port is not blocked by a firewall.

Ensure that the NNMi management server can directly address the northbound application by host and port.
Verify that the integration is running correctly:
1. In the NNMi console, open the NNMi–Northbound Interface Destinations form (Integration Module Configuration > Northbound).
2. Select a destination, and then click Edit.
3. Verify that the Enabled check box is selected.
If the northbound destination includes management events, verify this functionality:
1. In the Closed Key Incidents view of the NNMi console, open any incident.
2. Set the incident lifecycle state to Registered, and then click Save.
3. Set the incident lifecycle state to Closed, and then click Save and Close.
4. After 30 seconds, determine whether the northbound application received an EventLifecycleStateClosed trap (or a LifecyleStateChangeEvent trap) for this incident should.
  - If the northbound application received the trap, continue with step 4.
  - If the northbound application did not receive the trap, configure a new northbound destination to connect with a different northbound application, and then repeat this test from step a.
    
    If the repeated test succeeds, the problem is with the first northbound application. Consult that application’s documentation for troubleshooting information.
    
    If the repeated test fails, contact Support for assistance.
If the northbound destination includes SNMP traps, verify this functionality:
1. Generate an SNMP trap against a node in the NNMi topology by entering the following command on the NNMi management server:
```
nnmsnmpnotify.ovpl -u username -p password –a \
discovered_node NNMi_node linkDown
```
  Where discovered_node is the hostname or IP address of a node in the NNMi topology and NNMi_node is the hostname or IP address of the NNMi management server.
2. After 30 seconds, determine whether the northbound application received the forwarded trap.
  - If the northbound application received the trap, the NNMi northbound interface is working correctly.
  - If the northbound application did not receive the trap, configure a new northbound destination to connect with a different northbound application, and then repeat this test from step a.
    
    If the repeated test succeeds, the problem is with the first northbound application. Consult that application’s documentation for troubleshooting information.
    
    If the repeated test fails, contact Support for assistance.
