[SOLVED] network bridge almost working, need help with physical device

I am using netctl and have created the bridge profile below. After enabling it and restarting my computer the bridge comes up with an ip address as expected however the physical Ethernet is getting an IP address as well (not expected). I am not able to determine why or how it continues to get an IP address as I confirmed systemd-networkd is disabled. Please let me know what I am missing.

sudo vi /etc/netctl/bridge
sudo netctl enable bridge

# bridge setup DHCP enp9s0
Description="bridge archlinux"
Interface=br0
Connection=bridge
BindsToInterfaces=(enp9s0)
IP=dhcp
    bridge_ports enp9s0

I have also attempted to turn off IP on the physical Ethernet by creating a second entry in netctl, however this does not work either.

Description="ethernet connection"
Interface=enp9s0
Connection=ethernet
BindsToInterfaces=(enp9s0)
IP=no

Looks like what was missing was to disable the dhcp server.

sudo systemctl disable dhcpcd.service

Any reason why you're using netctl?  Your initi system has this support natively.

@graysky, I did end up switching back to  initi system and was able to get it working flawlessly.
