Description Michael Burman 2016-08-21 08:01:47 UTC

Description of problem:
[NetworkManager] - 'nmcli' Bond slaves remain with BOOTPRORTO=dhcp although we configured them with disabled method. 

When using nmcli tool and configuring bond with slaves, the ifcfg files of the bond remain with BOOTPRORTO=dhcp, although we configured it to be disabled.

For example:

nmcli connection add type bond con-name bond1 ifname bond1 mode active-backup; \
nmcli con mod id bond1 ipv4.addresses 10.35.y.x/24 ipv4.gateway 10.35.y.254 ipv4.method manual; \
nmcli connection modify id enp6s0 connection.slave-type bond connection.master bond1 connection.autoconnect yes ipv4.method disabled; \
nmcli connection modify id enp4s0 connection.slave-type bond connection.master bond1 connection.autoconnect yes ipv4.method disabled; \
nmcli connection up id bond1; \
nmcli connection up id enp4s0; \
nmcli connection up id enp6s0

- ifcfg files after the nmcli configurations:

Version-Release number of selected component (if applicable):
NetworkManager-1.0.6-30.el7_2.x86_64
kernel - 3.10.0-327.28.2.el7.x86_64

How reproducible:
100

Steps to Reproduce:
1. configure bond from 2 slaves using nmcli. Set the slaves with 'disabled' ipv4.method

Actual results:
The ifcfg files of the slaves contain BOOTPRORTO=dhcp

Expected results:
bootproto should be disabled. BOOTPROTO=none

Comment 2 Aniss Loughlam 2016-08-22 19:25:57 UTC

same result BOOTPRORTO=dhcp is confirmed with:
uname -r
3.10.0-327.el7.x86_64
NetworkManager -V
1.0.6-27.el7

Comment 3 Thomas Haller 2016-08-23 11:42:42 UTC

note that slave connections never have any IPv4/IPv6 settings, thus NetworkManager will ignore the BOOTPROTO=dhcp setting.


does this cause any problem with initscripts?
