Turning Off DHCP
By default, when Photon OS first starts, it creates a DHCP network configuration file or rule, which appears in
/etc/systemd/network, the highest priority directory for network configuration files with the lowest priority filename:
cat /etc/systemd/network/99-dhcp-en.network [Match] Name=e* [Network] DHCP=yes
To turn off DHCP for all Ethernet interfaces, change the value of
no, save the changes, and then restart the
systemctl restart systemd-networkd
If you create a configuration file with a higher priority filename (e.g.
10-static-en.network), it is not necessary but still recommended to turn off DHCP.
