Unnumbered Interfaces

NNMi enables you to discover and monitor unnumbered interfaces and the associated layer 2 connections, including those in a Global Network Management (GNM) environment.

If you are enabling layer 2 connectivity for unnumbered interfaces in a GNM environment, you must do so on both the regional managers and the global manager.

You can configure (enable and disable) layer 2 connectivity for unnumbered interfaces using NNMi’s Configuration > Discovery workspace. See the NNMi Help for Administrators for more information.

Optionally, use the nnmunnumberedcfg.ovpl command to configure unnumbered interface connectivity. See the nnmunnumberedcfg.ovpl reference page, or the Linux manpage, for more information.

Note Node Groups are not replicated between regional managers and the global manager.

You can use the nnmunnumberedcfg.ovpl command to replicate configuration settings between a global manager and regional managers. This functionality lets you define Node Groups differently between the regional managers and the global manager. For example, you can define all routers at the global level and define only a subset of routers at each regional manager.

It is recommended that you have different configurations on the global manager than on the regional managers. For example, unless you are managing nodes directly from the global manager, there is no need to configure the optional subsets on the global manager because the data is only gathered at the regional manager.
