Network Interface

Available in Classic

Network Interface describes the screen configuration of the Network Interface menu and network interface information, and explains how to create and manage the network interface.

Network Interface is a service for creating network interfaces that can be assigned to servers. Servers with the network interface applied are able to conduct independent network communications through subnets.
