Howto - DHCP Client - VLAN ?

[mauric]

Hello
i need to create on running Debian 10 a DHCP Client that will running with VLAN.

Network Server are distribute dhcp range Vlan30, my windows clients can do this,
but now i need this also on my Debian machines.

apt-get install vlan

/etc/modules
8021q

i add this settings to /etc/betwrok/interface
auto enp0s25
iface enp0s25.20 inet dhcp
vlan-raw-device enp0s24

but here my Debian dont run the acknoledge with the DHCP Server, and no ip will be asigned.
thanks for possible update

Several inconsistencies.
You write VLAN 30 but configure enp0s25.20
You configure enp0s25.20 but defined enp0s24 as the raw interface.
You configure enp0s25.20 but bring up enp0s25 only.

Yes.

PS : you should consider using cut&paste to avoid typoes when posting configuration files, commands or outputs.

ok... but now if restarting the machine thakes 4-5 min

"a start Job is running for raise network interface (5m / 5m)"

[p.H]

Well then... you can run

Code: Select all

ifdown enp0s25.30
ifup -v enp0s25.30

and see what's wrong.
