6.2.8 Interface discovery range
NNMi enables you to define a filter to specify a range of interfaces to be discovered. This is especially useful for discovering only subsets of interfaces when the node is large. When the Excluded Interfaces option is used, interfaces are filtered after information has been obtained from devices. On the other hand, when an interface discovery range is specified, information about interfaces that are not in the specified range is not requested from NNMi. Therefore, range-based discovery can improve discovery performance on large devices when only some of the interfaces are managed.
On the Included Interface Ranges tab of the Discovery Configuration form you use the system object ID prefix value and ifIndex value to define an interface range. For details, see NNMi Help.
