Hi,

I need to set the "description" field out of nmstate so I can mark some interfaces that will be processed by nmstate later on. Do you know if it's possible to do it with nmcli or busctl/dbus-send ?

Hi Quique,

With these command:

nmcli -f NAME,DBUS-PATH,FILENAME c show

You will get confutation file or dbus path of the setting.

You may chose any of this way:

* Parse configuration file and search for `nmstate.interface.description`

* Use dbus method GetSettings

* Submit feature request to NetworkManager asking for nmcli showing user section.

Example output of qdbus command:

[fge@c8s eth]$ sudo qdbus --literal --system \ org.freedesktop.NetworkManager \ /org/freedesktop/NetworkManager/Settings/2 \ org.freedesktop.NetworkManager.Settings.Connection.GetSettings
