I always thought that its not very complicated. But in fact, to have it working I had to spend some time.

Bonding let us combine many ethernet devices into one or more groups, with right switch configuration it can duble bandwitch on bond0 interface so it can be quite usefull for example on our gateway. Let add vlan support for all of this.

Creating bond0

First of all we need to apt-get install ifenslave (on older systems you can find ifenslave-2.4 nad ifenslave-2.6)

Now lets create configuration for our first bond0 interface.
Edit /etc/network/interfaces

...
auto bond0
iface bond0 inet manual
      bond-miimon 100
      lacp_rate slow
      slaves eth0 eth1
...

Then we need to be sure, that our bonding will load after a reboot. Lets create a file in /etc/modprobe.d/ and lets call it bonding

alias bond0 bonding
options bonding mode=1 miimon=100 downdelay=200 updelay=200

Now if we dont want to have vlans, we can set the ip for the interface finish the job. Bue we want vland ontop of bond0.

Creating vlans on bond0

Like with bond, we need to apt-get install vlan to be able to work with vlans. (its in the debian standard repo)

Again we need to edit /etc/network/interfaces

auto vlan4
auto vlan5
auto vlan101

# VLAN 4
iface vlan4 inet static
address 192.168.10.8
netmask 255.255.255.192
network 192.168.10.0
broadcast 192.168.10.63
mtu 1500
vlan_raw_device bond0

# VLAN 5
iface vlan5 inet static
address 10.0.111.8
netmask 255.255.255.0
network 10.0.111.0
broadcast 10.0.111.255
mtu 1500
vlan_raw_device bond0

# VLAN 101
iface vlan101 inet static
address 172.12.101.8
netmask 255.255.255.0
network 172.12.101.0
broadcast 172.12.101.255
gateway 172.12.101.1
mtu 1500
vlan_raw_device bond0

Like you can see, vlan_raw_device is pointing the bond0 raw interface. Now its time to create our vlans in the system.

 rumplebump:~# vconfig add bond0 194

During the creation, you can have an error like this:

---dmesg ---
 Jul  9 12:14:45 rumplebump kernel: register_vlan_device: VLANs not supported on  bond0.

To solve this, you should edit bond0 configuration in /etc/network/interfaces

auto bond0
iface bond0 inet manual
    bond-mode 802.3ad  <---- add this!
    bond-miimon 100
    xmit_hash_policy layer2+3 <--- add this!
    lacp_rate slow
    slaves eth0 eth1

Now all we need is reboot (you can create vlnas with vconfig and reload the networking but do a reboot if you can)

After that, you should have a working bond0 interfave with vlans on top.

rumplebump:~# cat /proc/net/vlan/config 
VLAN Dev name    | VLAN ID
Name-Type: VLAN_NAME_TYPE_PLUS_VID_NO_PAD
vlan4        | 4  | bond0
vlan5        | 6  | bond0
vlan101      | 101  | bond0
