Generic NEs

Overview

The NFM-P provides limited management support of generic NEs, or GNEs, which are typically non-Nokia devices.

NFM-P GNE support is limited to the following:

• display on topology maps and in the navigation tree, interfaces excluded

• physical link creation and representation as a graphical and logical object

• trap translation into alarms

• status polling using enterprise MIB object interface alarms

• Telnet, SSH, and web sessions invocation

• provisioning using CLI scripts

• inclusion in a service instance using NFM-P scripts

Statistics support

The NFM-P supports the collection of a limited set of statistics counters from standard system, interface, and routing MIBs on GNEs. These statistics are processed and presented in the same manner as statistics from other devices. You can view GNE statistics on the Statistics tab of a GNE interface properties form, retrieve them using the XML API, and display them graphically using the NFM-P Statistics Plotter.

Note: If persistent SNMP indexes are not enabled on a GNE, one or more GNE interface indexes may change after a GNE reboots. This can cause a mismatch between the statistics records collected before the reboot and the current interface indexes. The NFM-P takes no action to identify or correct such a mismatch.

Alarm support

By default, the NFM-P supports a limited number of standard system and interface SNMP traps for GNEs. You can configure the NFM-P to raise user-defined alarms in response to specific GNE traps using alarm catalogs. See GNE commissioning for information about configuring user-defined alarms for GNEs.

GNE drivers

For some specific GNEs, drivers have been developed to extend management of the NE beyond the basic GNE management functions. Drivers translate proprietary MIBs to the normalized NFM-P model. See Chapter 7, Device management using drivers for information about drivers.
