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.
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.
