28.7.1 Local Northbound application
If the trap-receiving component of the Northbound application is located on the NNMi management server, the following considerations apply to the configuration of the NNMi Northbound interface:
The trap-receiving component of the Northbound application must be installed and configured identically on the active and standby NNMi management servers. Configure SNMP trap reception on the same port on both NNMi management servers.
Configure the NNMi Northbound interface on the primary NNMi management server only.
On the NNMi Northbound Interface Destination form, select either the NNMi FQDN or the Use Loopback option for Host identification.
At startup, the NNMi Northbound interface determines the correct name or IP address of the current NNMi management server. In this way, the Northbound interface sends traps to the trap-receiving component of the Northbound application on the active NNMi management server.
