The Networking Configuration features lets you create a variety of advanced networking setups using your physical network ports, including link-aggregations, virtual NICs (VNICs), virtual LANs (VLANs), and multipathing groups. You can then define any number of IPv4 and IPv6 addresses for these abstractions, for use in connecting to the various data services on the system.
There are four components to a system's network configuration:
Devices - Physical network ports. These correspond to your physical network connections or IP on InfiniBand (IPoIB) partitions.
Datalinks - The basic construct for sending and receiving packets. Datalinks may correspond 1:1 with a device (that is, with a physical network port) or IB Partition, or you may define Aggregation, VLAN and VNIC datalinks composed of other devices and datalinks.
Interface - The basic construct for IP configuration and addressing. Each IP interface is associated with a single datalink, or is defined to be an IP MultiPathing (IPMP) group comprised of other interfaces.
Routing - IP routing configuration. This controls how the system will direct IP packets.
