Hi,
Thank you very much for the good answer.
nmcli connection show "$PROFILE" is able to show the default value. For example:
802-11-wireless.powersave: 0 (default)
`man NetworkManager.conf` provides useful info too.
` man nm-settings` shows some info as well.
Thanks.
Regards
victor

Hi,
in NetworkManager, you create connection profiles (and activate them).
Connection profiles consist of many properties, that you see with `nmcli
connection show "$PROFILE"` (`man nm-settings`). A property is always set, so
there is no "default". And it was the client tool that created the profile --
usually profiles are created by the user.
Actually, some properties have a special "default" value, where the fallback
value can be configured in NetworkManager.conf. See "CONNECITON SECTION" in
`man NetworkManager.conf`. But essentially the value is still specified in the
profile, and it merely says: look at NetworkManage.conf to get the actual value.
If you use a client tool to create a profile (like calling `nmcli connection
add type ethernet`), then at that time a lot of default values will be chosen.
But it was still entirely up to the client tool that you are using. E.g. in
nmcli you could have specified those properties right away. For example, if you
open nm-connection-editor to create a new profile, then the dialog will also be
pre-populated with default values -- depending on the tool.
OK, this wasn't a very useful answer so far :)
You ask about "security and radio mode" and " TX power, radio channel, radio
channel list". It's not clear what you mean there. There are some related
properties of connection profiles, like wifi.powersave, wifi.tx-power,
wifi.channel. See `man nm-settings`.
What default these properties have, depends on how you configure the profile
when you create it (or whether the tool allows you to configure them). But
commonly, the default at that point is something that makes sense (ie. not
specify/restrict things). Check `nmcli connection show`.
best,
Thomas
