You have to configure it in the configtool, or edit the ecos.ecc file
if you are using ecosconfig. Alternatively, apply an import file. The
following is the import file I use to configure the ethernet interface
to IP address 10.0.0.211. Adjust to suit your network.

cdl_savefile_command cdl_package { value_source user_value wizard_value inferred_value };

cdl_savefile_command cdl_option { value_source user_value wizard_value inferred_value };
cdl_savefile_command cdl_interface { value_source user_value wizard_value inferred_value };
