Known Issues When Cleaning Up IPv6 Inventory

You could experience leftover IPv6 inventory in the following situation:

NNMi successfully uses SNMP to manage an IPv6 node, then the node becomes inaccessible before the next discovery.

Due to the design of the existing discovery system, the discovery process cannot update a node that loses its ability to communicate using SNMP. To remove these remaining nodes, you must fix the communication problem, then use the Actions > Configuration Poll command located in the NNMi console to obtain configuration information from these nodes. For native IPv6 nodes, delete the node directly from the NNMi console.
