CNFS network setup

In addition to one set of IP addresses for the GPFS cluster, a separate set of one or more IP addresses is required for CNFS serving.

The GPFS cluster can be defined over an IPv4 or IPv6 network. The IP addresses specified for CNFS can also be IPv4 or IPv6. The GPFS cluster and CNFS are not required to be on the same version of IP, but IPv6 must be enabled on GPFS to support IPv6 on CNFS.

Note: CNFS also requires the daemon network interface to accept incoming SSH connections.
