14.2 Prerequisites for using the NNMi IPv6 management feature
For details about the management server specifications and about NNMi installation, see the Release Notes.
To use native IPv6 communication, the NNMi management server must be a dual-stacked system, meaning that it communicates using both IPv4 and IPv6.
For details about the supported operating systems for IPv6, see the Release Notes. There are other requirements, as listed below:
-
You must enable and configure IPv4 on at least one network interface.
-
You must enable IPv6 and have a unicast address (that is not a link-local unicast address), such as 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 must 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.
- Reference 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 with IPv6 addresses.
The DNS server used by the NNMi management server must resolve host names to and from IPv6 addresses. That means the DNS server must map a host name 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 or display DNS host names for nodes using IPv6 addresses.
