Hi.
Anyone can help me?
I have Linux 3.10.0-123.20.1.el7.x86_64

# cat /etc/os-release
NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"
PRETTY_NAME="CentOS Linux 7 (Core)"

I added new virtual interfaces (br71 and vlan71) via NetworkManager

# cat /etc/sysconfig/network-scripts/ifcfg-br71
DEVICE=br71
STP=no
TYPE=Bridge
BOOTPROTO=none
IPV6INIT=no
NAME=br71
ONBOOT=yes

# cat /etc/sysconfig/network-scripts/ifcfg-vlan71
VLAN=yes
TYPE=Vlan
DEVICE=vlan71
PHYSDEV=team0
VLAN_ID=71
REORDER_HDR=0
BOOTPROTO=none
IPV6INIT=no
NAME=vlan71
ONBOOT=yes
NM_CONTROLLED=yes
BRIDGE=br71

Q: When interface going up (nmcli connection up br71) it was trying
to get ip-addres via dhclient (but options BOOTPROTO=none uses). Why?

nmcli device status
DEVICE    TYPE      STATE                                  CONNECTION
vlan71    vlan      connected                              vlan71
br71      bridge    connecting (getting IP configuration)  br71

Something wrong in my config files?
Thx.
