[moo can <moocan2112 yahoo fr>]

Hello,

I'm trying to setup VLAN using NetworkManager GUI.

Is there a manual ?

1 - I create an Ethernet

    Device : enp1s0

    IPv4 Settings: DHCP

    All other option : default

2 - I create a NEW VLAN

    Parent Interface: enp1s0 (via “TEST VLAN”)

    VLAN id : 3000

    VLAN Interface name: VLAN3000

    IPv4 Settings: DHCP

    All other option : default

NetworkManager never activate the VLAN.

Interface "VLAN3000" appear and disappear... and then

ifconfig do not show the "VLAN3000" interface

after

How to create a VLAN which is affected to an Ethernet connection and which can be activated simply as the other.

How to match a VLAN with an Ethernet Connection using NetworkManager GUI ?

Is it supported ?

Using vconfig it is working but I would like to be able to ativate or desactivate simply the VLAN+Ethernet Connection.

Thank you in advance for your help.

Kind Regards
