You can see the `TYPE_SPECIFIC_OPTIONS` list in the [citetitle]_pass:attributes[{blank}]*nmcli*(1)_ man page.
The [option]`connection.id` is the name of a _connection profile_ and should not be confused with the interface name which denotes a device (`wlan0`, `ens3`, `em1`). However, users can name the connections after interfaces, but they are not the same thing. There can be multiple connection profiles available for a device. This is particularly useful for mobile devices or when switching a network cable back and forth between different devices. Rather than edit the configuration, create different profiles and apply them to the interface as needed. The [option]`id` option also refers to the connection profile name.

An identification string assigned by the user to a connection profile. Id can be used in nmcli connection commands to identify a connection. The NAME field in the command output always denotes the connection id. It refers to the same connection profile name that the con-name does.
A name used for the connection profile. If you do not specify a connection name, one will be generated as follows:
