1. From ip link show command, find the network interface you want to make static.
   
   [0]ip link show
   1: lo: mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default
       link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
   2: em1: mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
       link/ether 2c:27:d7:2b:ee:76 brd ff:ff:ff:ff:ff:ff
   
   
2. In /etc/sysconfig/network-scripts/ifcfg-em1
   
   TYPE="Ethernet"
   DEVICE="em1"
   ONBOOT="yes"
   NM_CONTROLLED="no"
   BOOTPROTO="static"
   IPADDR=172.17.172.79
   NETMASK=255.255.252.0
   GATEWAY=172.17.172.1
   
   
3. In /etc/resolv.conf
