= The nmcli options
|
||
|
|
|
||
|
|
Following are some of the important [application]*nmcli* property options:
|
||
|
|
|
||
|
|
|
||
|
|
[option]`connection.type`::
|
||
|
|
+
|
||
|
|
A connection type. Allowed values are: adsl, bond, bond-slave, bridge, bridge-slave, bluetooth, cdma, ethernet, gsm, infiniband, olpc-mesh, team, team-slave, vlan, wifi, wimax. Each connection type has type-specific command options. For example:
|
||
|
|
+
|
||
|
|
** A `gsm` connection requires the access point name specified in an [option]`apn`.
|
||
|
|
+
|
||
|
|
[literal,subs="+quotes,verbatim,macros"]
|
||
|
|
....
|
||
|
|
nmcli c add connection.type gsm apn pass:quotes[_access_point_name_]
|
||
|
|
....
|
||
|
|
+
|
||
|
|
** A `wifi` device requires the service set identifier specified in a [option]`ssid`.
|
||
|
|
+
|
||
|
|
[literal,subs="+quotes,verbatim,macros"]
|
||
|
|
....
|
||
|
|
nmcli c add connection.type wifi ssid
|
||
|
|
_My identifier_
|
||
|
|
....
|
||
|
|
|
||
|
|
You can see the `TYPE_SPECIFIC_OPTIONS` list in the [citetitle]_pass:attributes[{blank}]*nmcli*(1)_ man page.
|
||
|
|
|
||
|
|
[option]`connection.interface-name`::
|
||
|
|
+
|
||
|
|
A device name relevant for the connection.
|
||
|
|
+
|
||
|
|
[literal,subs="+quotes,verbatim,macros"]
|
||
|
|
....
|
||
|
|
nmcli con add connection.interface-name _eth0_ type _ethernet_
|
||
|
|
....
|
||
|
|
|
||
|
|
[option]`connection.id`::
|
||
|
|
+
|
||
|
|
A name used for the connection profile. If you do not specify a connection name, one will be generated as follows:
|
||
|
|
+
|
||
|
|
[literal,subs="+quotes,verbatim,macros"]
|
||
|
|
....
|
||
|
|
_connection.type -connection.interface-name_
|
||
|
|
....
|
||
|
|
+
|
||
|
|
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.
|
||
|
|
|
||
|
|
The most important options for [application]*nmcli* commands such as `show`, `up`, `down` are:
|
||
|
|
|
||
|
|
[option]`id`::
|
||
|
|
+
|
||
|
|
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.
|
||
|
|
|
||
|
|
[option]`uuid`::
|
||
|
|
+
|
||
|
|
A unique identification string assigned by the system to a connection profile. The `uuid` can be used in [command]`nmcli connection` commands to identify a connection.
