Discover Interface Ranges

NNMi enables you to specify a range of interfaces to be discovered by defining a filter. This is particularly helpful when you have large nodes where you only want to discover a subset of the interfaces. When you specify a range of interfaces to be discovered, NNMi does not ask for information about interfaces outside that range; whereas, using the excluded interface option filters interfaces after retrieving the information from the device. Therefore, range-based discovery can improve discovery performance for large devices, especially when you do not want to manage all the interfaces on such devices.

The included interface ranges filter, defined on the Included Interface Ranges tab of the Discovery Configuration form, uses the System Object ID prefix and the ifIndex values to define the interface range. See the NNMi help for more information.
