Worked with Bob Fournier to verify this bug
Installed: /etc/yum.repos.d/rhos-release-10.repo
# rhos-release 10 -p 2017-09-20.2
environment
[root@undercloud ~]# rpm -qa | grep os-net-config-5.2
os-net-config-5.2.0-4.el7ost.noarch
1. checked the patch was there by inspection
2. running os-net-config using —noop with —debug to print out what it would do
3. passed a config.json file that had a bond in it and also mapping file that reversed the normal mapping, so nic1 is mapped to eth1 and nic2 is mapped to eth0
Output
[2017/06/13 11:56:11 AM] [INFO] nic2 in mapping file mapped to: eth0
