Ethernet static address

[MattMueller]

I use a Board KC868-A16 Rev1.6.3 with tasmota firmware-en-a16.bin from here. After installation I have two ip-addresses (via dhcp) one for wifi and one for ethernet.
In the console I can change the wifi adress to a static address with the command ipaddress1 xxx.xxx.xxx.xxx , that works fine. 
But how can I change the ethernet-address to a static one?

Web UI → Console , you can input these command:
EthIPAddress 192.168.1.100
EthGateway 192.168.1.1
EthSubnetmask 255.255.255.0
EthDNSServer1 8.8.8.8
EthDNSServer2 1.1.1.1
Restart 1

Thank You for the quick reply, but this produces the error message "Unknown command"

The command EthIPAddress is unknown in my version, does that mean, that the compilation I've used (this one) is not ok?

maybe you need enable ethernet function when compile.
