.fi
.if n \{\

This command activates a VPN connection profile enabling nmcli to interact with the user (\*(Aq\-\-ask\*(Aq): this will allow nmcli to prompt for the VPN password on the command line when the
\fIpassword\-flags\fR
are set to \*(Aq0x02\*(Aq (\*(Aqalways ask\*(Aq, see
\fBnm-settings\fR(5)
)\&. This is particularly useful for OTP based VPNs, as the user needs to be prompted for the password each time the connection is activated\&.

$ \fBnmcli con add type ethernet ifname eth2 master mybond0\fR
.fi
.if n \{\
.RE
.\}
.PP
This example demonstrates adding a bond master connection and two slaves\&. The first command adds a master bond connection, naming the bonding interface
\fImybond0\fR
and using
\fIactive\-backup\fR
mode\&. The next two commands add slaves connections, both enslaved to
\fImybond0\fR\&. The first slave will be bound to
\fIeth1\fR
interface, the second to
\fIeth2\fR\&.
.PP
\fBExample\ \&9.\ \&Adding a team master and two slave connection profiles\fR
.sp

$ \fBnmcli con add type ethernet con\-name Team1\-slave2 ifname em2 master Team1\fR
.fi
.if n \{\
.RE
.\}
.PP
This example demonstrates adding a team master connection profile and two slaves\&. It is very similar to the bonding example\&. The first command adds a master team profile, naming the team interface and the profile
\fITeam1\fR\&. The team configuration for the master is read from
\fIteam1\-master\-json\&.conf\fR
file\&. Later, you can change the configuration with
\fImodify\fR
command (\fBnmcli con modify Team1 team\&.config team1\-master\-another\-json\&.conf\fR)\&. The last two commands add slaves profiles, both enslaved to
\fITeam1\fR\&. The first slave will be bound to the
\fIem1\fR
interface, the second to
\fIem2\fR\&. The slaves don\*(Aqt specify
\fIconfig\fR
and thus
\fIteamd\fR
will use its default configuration\&. You will activate the whole setup by activating both slaves:
.sp
.if n \{\
.RS 4
.\}
.nf
$ \fBnmcli con up Team1\-slave1\fR
$ \fBnmcli con up Team1\-slave2\fR
.fi
.if n \{\
.RE
.\}
.sp
By default, the created profiles are marked for auto\-activation\&. But if another connection has been activated on the device, the new profile won\*(Aqt activate automatically and you need to activate it manually\&.

$ \fBnmcli con modify TowerBridge bridge\&.stp no\fR
.fi
.if n \{\
.RE
.\}
.PP
This example demonstrates adding a bridge master connection and two slaves\&. The first command adds a master bridge connection, naming the bridge interface and the profile as
\fITowerBridge\fR\&. The next two commands add slaves profiles, both will be enslaved to
\fITowerBridge\fR\&. The first slave will be tied to
\fIens3\fR
interface, the second to
\fIens4\fR\&. The last command will disable 802\&.1D STP for the TowerBridge profile\&.

$ \fBnmcli \-p con show my\-con\-em1\fR
.fi
.if n \{\
.RE
.\}
.PP
The first command adds an Ethernet connection profile named
\fImy\-con\-em1\fR
that is bound to interface name
\fIem1\fR\&. The profile is configured with static IP addresses\&. Three addresses are added, two IPv4 addresses and one IPv6\&. The first IP 192\&.168\&.100\&.100 has a prefix of 24 (netmask equivalent of 255\&.255\&.255\&.0)\&. Gateway entry will become the default route if this profile is activated on em1 interface (and there is no connection with higher priority)\&. The next two addresses do not specify a prefix, so a default prefix will be used, i\&.e\&. 32 for IPv4 and 128 for IPv6\&. The second, third and fourth commands modify DNS parameters of the new connection profile\&. The last
\fIcon show\fR
command displays the profile so that all parameters can be reviewed\&.

\fIspoof\-check\fR
features respectively enabled and disabled\&. VF number 2 has a maximum transmission rate of 20Mbps\&. The kernel is instructed to not automatically instantiate a network interface for the VFs\&.

Example session in the nmcli interactive connection editor\&. The scenario creates an Ethernet connection profile with static addressing (IPs and DNS)\&.
.PP
\fBExample\ \&17.\ \&Bluetooth connection profiles\fR
.PP
NetworkManger supports both connecting to NAP and DUN devices as a client\&. It also supports sharing the network via a NAP server\&.
.PP
For NAP client connections, NetworkManager automatically creates a suitable in\-memory profile for paired devices if none is available\&. You may use that generated profile directly, but you may also modify and persist it, which will prevent to automatically re\-create it\&. You may also create a profile from scratch\&. For example, the following uses DHCP and IPv6 autoconf for address configuration:
.sp
.if n \{\
.RS 4
.\}
.nf
$ \fBnmcli connection add type bluetooth con\-name "Profile for My Bluetooth Device (NAP)" autoconnect no bluetooth\&.type panu bluetooth\&.bdaddr "$BDADDR"\fR
.fi
.if n \{\
.RE
.\}
.PP
For DUN connections, the user needs to configure modem settings and hence no profile gets created automatically\&. The modem settings depend on your device and you either need a "gsm" or a "csma" section\&. For example,
.sp
.if n \{\
.RS 4
.\}
.nf
$ \fBnmcli connection add type bluetooth con\-name "Profile for My Bluetooth Device (DUN)" autoconnect no bluetooth\&.type dun bluetooth\&.bdaddr "$BDADDR" gsm\&.apn apn\&.com\fR
.fi
.if n \{\
.RE
.\}
.PP
Finally, you can create a bluetooth hotspot\&. BlueZ implements those as a bridge device, so such profiles also have a bridge section\&. Also, you probably want to set IP methods as "shared", so that clients get automatic IP addressing\&. Note that the "shared" IPv4 method requires dnsmasq to be available\&.

Creates a connection file in keyfile format without using the NetworkManager service\&. This allows for use of familiar

Read and write a connection file without using the NetworkManager service, modifying some properties along the way\&.

Device \*(Aqeth0\*(Aq successfully disconnected\&.
Type "Yes" to commit the changes: No
Checkpoint was removed\&.
.fi
.if n \{\
.RE
.\}
.PP
In this example the device eth0 was disconnected with the eth0 checkpoint taken\&. The user didn\*(Aqt confirm that the change is good, so the eth0 was brought back to the state it was when the checkpoint was taken\&.
.PP
If the command being run unintentionaly brings down the remote connection (such as a
\fBssh\fR(1)
session) to the very machine it\*(Aqs being run on, the user wouldn\*(Aqt be able to confirm the success and the connectivity would end up being restored after a timeout\&.
.PP
If, on the other hand, the command results in a success, the user could just confirm, causing the checkpoint to be abandoned without a rollback:
.sp
.if n \{\
.RS 4
.\}
