Static and Dynamic IP on a Single Interface
Oct 2017
Introduction
During the configuration of an MFEL (CentOS 7.2, MFEL 7x) I suddenly lost connection. After some investigation i noticed that my control interface had two addresses. When I did an ip a on the interface, I saw something similar to the section below.
6: enp4s0f0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000 link/ether 00:1e:67:eb:69:4c brd ff:ff:ff:ff:ff:ff inet 10.43.3.67/19 brd 10.43.31.255 scope global enp4s0f0 valid_lft forever preferred_lft forever inet 10.43.2.244/22 brd 10.43.2.254 scope dynamic enp4s0f0 valid_lft forever preferred_lft forever
I tried to add NM_Controlled=no to the interface configuration file, but that didn't help. So in the end I had to disable the built in Network Manager, which to be honest we don't use because our interfaces are always set to Static.
Disable Network Manager
