IFCONFIG

(InterFace CONFIGurator) A Mac, Unix and Linux command line utility that is used to display and manage the IP address assigned to the machine it is running in. Typing ifconfig at the command line will display all the IP interfaces currently assigned. For example, in a computer with Ethernet and Wi-Fi, there will be two IP addresses. See IPCONFIG, the Windows counterpart.

Then the virtual Ethernet port can be accessed in the user space via the system command "ifconfig." At this time, we can create OpenFlow software switches on NMP.
<identificadorHost> ifconfig <identificadorInterfaz> inet6 add <direccionIPv6AAsignar>.
Also, all the virtual interfaces should be reported by ifconfig:
[root@p01001534852033 ~]# ifconfig | grep enp4s | cut -c 1-53
Whenever a node needs IP based application execution with other node a private IP address is initialized by using the ifconfig utility.

Currently, there are important efforts to achieve this objective; the Open Networking Foundation (ONF) published the IFConfig Protocol [48] as a first step to the configuration of OpenFlow devices.
The software based features of the set-top box are: security (authentication service), encryption provider (certificates), shell & user interface (command processor & console window), multimedia components, network user interface, network utilities (IfConfig, Ping, Route), codecs and renderers, power management, multimedia waveform, audio, XML core, Session Initiation Protocol (SIP), WAN (Wide Area Network), wired LAN (Local Area Network), and wireless LAN.
IPconfig (and its counterpart in the Unix world ifconfig) provides useful information on Ethernet/IP interfaces that can tell the user if there is an issue with the availability of interfaces and dynamic addressing.
1) Identify Network Interfaces: The "ifconfig" tool provides information about the available network adapters, sample output is provided below.
From the root prompt type in 'ifconfig' and hit Enter.
When we issued ifconfig command at the terminal the virtual interfaces veth0 and veth1 are present which are shown in Figure 12.
