<code>
nmcli connection add ifname br0 type bridge con-name br0
</code>

Ethernet Schnittstelle hinzufügen

<code>
nmcli connection add type bridge-slave ifname eth1 master br0
</code>


====== Verbindung konfigurieren ======

mit goto navigieren, mit back zurück. describe beschreibt Optionen.

Z.B. mit describe bridge:

<code>
===| nmcli interactive connection editor |===

Adding a new 'bridge' connection

Type 'help' or '?' for available commands.
Type 'describe [<setting>.<prop>]' for detailed property description.

You may edit the following settings: connection, bridge, 802-3-ethernet (ethernet), ipv4, ipv6
nmcli> describe
Error: no setting selected; valid are [connection, bridge, 802-3-ethernet (ethernet), ipv4, ipv6]
use 'goto <setting>' first, or 'describe <setting>.<property>'
nmcli> describe bridge
<<<bridge>>>

=== [mac-address] ===
[NM property description]
If specified, the MAC address of bridge. When creating a new bridge, this MAC address will be set. When matching an existing (outside NetworkManager created) bridge, this MAC address must match.

=== [stp] ===
[NM property description]
Controls whether Spanning Tree Protocol (STP) is enabled for this bridge.

=== [priority] ===
[NM property description]
Sets the Spanning Tree Protocol (STP) priority for this bridge.  Lower values are "better"; the lowest priority bridge will be elected the root bridge.

=== [forward-delay] ===
[NM property description]
The Spanning Tree Protocol (STP) forwarding delay, in seconds.

=== [hello-time] ===
[NM property description]
The Spanning Tree Protocol (STP) hello time, in seconds.

=== [max-age] ===
[NM property description]
The Spanning Tree Protocol (STP) maximum message age, in seconds.

=== [ageing-time] ===
[NM property description]
The Ethernet MAC address aging time, in seconds.
</code>

Mit set wird eine property gesetzt

z.B.

set bridge.stp true

set bridge.mac 78:24:af:88:eb:99

<code>
nmcli ipv4> set ipv4.addresses 192.168.72.1
nmcli ipv4>?
