Prerequisites

Review the NNMi Deployment Reference, NNMi Release Notes, and NNMi Support Matrixfor details on management server specifications and NNMi installation.

To use native IPv6 communication, the NNMi management server must be a dual-stacked system, meaning that it communicates using both IPv4 and IPv6.

This text is used in the following locations:

IPv6 chapter in the Deployment Reference

UCMDB integration chapter in the Integration Reference

Note If you have IPv6 discovery configured on NNMi, and are using the Universal CMDB (UCMDB) integration, the UCMDB Discovery and Dependency mapping (DDM) import task fails. You need to disable IPv6 discovery to use the UCMDB integration with NNMi.

Additional requirements for IPv6 include the following:

  • You must enable and configure IPv4 on at least one network interface.
  • You must enable IPv6 and have a global unicast address or a unique local unicast address configured on at least one network interface that is connected to the IPv6 network you want to manage.
  • You must configure IPv6 routes on the NNMi management server to enable NNMi to communicate with any devices you want NNMi to discover and monitor using IPv6.

Note You can use an IPv4-only NNMi management server, but doing so will limit NNMi from fully managing IPv4/IPv6 dual-stacked devices. For example, if you use an IPv4-only management server, NNMi cannot discover IPv6-only devices, cannot discover using IPv6 seeds and hints, and cannot monitor for faults on devices having IPv6 addresses.

The DNS server used by the NNMi management server must resolve hostnames to and from IPv6 addresses. For example, it must be able to resolve to and from an AAAA DNS record. That means the DNS server must map a hostname to a 128-bit IPv6 address. If an IPv6-capable DNS server is not available, NNMi will still function correctly; however NNMi does not determine nor display DNS hostnames for nodes using IPv6 addresses.
