Please add 802.1Q/VLAN tagging support to NetworkManager

I use VLANs too, and had to remove network manager to get Pidgin to automatically connect. Firefox is only coming up online because you can tell it to ignore NM in about:config.

"Planned" in NM 0.9.X, or at least on some future roadmap. As such, I'm marking this Wishlist/Triaged

I found this activity upstream:

    https://mail.gnome.org/archives/networkmanager-list/2011-October/msg00209.html

which seems to be the basis for the claim that VLAN support has been added to NM. But this is only support for VLANs in RedHat and ilk.

No, it's supported in NM regardless of the distro used; it's just not easy to configure; depends on the proper use of the config files. Closing as Fix Released.

To configure it you'll need to create a new connection manually in /etc/NetworkManager/system-connections; something like a file "VLAN615", with the following contents (uuid needs to be generated, which can be done with 'uuidgen -r'):

[connection]
id=VLAN615
uuid=ed3b2385-9016-45c6-a277-fa7e5be8fe9d
type=vlan

[vlan]
parent=eth0
id=615

[ipv6]
method=auto

[ipv4]
method=auto

The available parameters for the [vlan] block are defined in source:
http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/libnm-util/nm-setting-vlan.c#n608

However, the actual names to use (as key=) for the parameters are the NM_SETTING_VLAN_* constants; which are defined here:
http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/libnm-util/nm-setting-vlan.h#n57

OK, but where is this documented other than here? Can we reopen this as a wish for additional documentation of some sort?

Thanks to everybody. That helped a lot.

Now, is there any chance to get the VLAN connection up as soon as a cable is connected? This works fine for 802-3-ethernet connections, but apparently not for VLAN connections, right?

Unfortunately, nm-applet does not even show the connection at all. I hoped, one could at least activate or deactive the VLAN connection with nm-applet. Editing configuration would not have been necessary.

So, at the moment, am I right, that there is no other way than entering

nmcli con up id VLAN1

whenever I connect the cable?

Thanks again

Linked to a Debian bug report I just filed asking for a note to be added somewhere in the vlan package that vlan doesn't work with NetworkManager.

Thomas, it would be best to open a bug upstream for documentation for VLAN... and/or anyway file a new bug here for the documentation too rather than reusing old bugs.

Michael: I think all you need for this is that the top section ('[connection]') is set "autoconnect=true" or so. It does work properly here as soon as a cable is connected (though I didn't have to add autoconnect).
