Configuring VLAN for host

I've set my proxmox as is written at https://pve.proxmox.com/wiki/Network_Configuration and it works correctly, host gets address from VLAN but in the GUI I see unkown type of bridge (it's named vmbr0v10) and can't edit it from GUI. Is it possible to set VLAN for host directly from GUI, not editing interfaces config file?
Any help appreciated.
 
My /etc/network/interfaces file:
Code: 
iface ens1f0 inet manual

iface eno1 inet manual

iface eno2 inet manual

iface eno3 inet manual

iface eno4 inet manual

iface ens1f0.10 inet manual

iface ens1f1 inet manual

auto vmbr0v10
iface vmbr0v10 inet static
        address 172.16.0.14/24
        gateway 172.16.0.1
        bridge_ports ens1f0.10
        bridge_stp off

auto bond0
iface bond0 inet manual
        bond-slaves eno1 eno2 eno3 eno4
        bond-miimon 100
        bond-mode balance-alb

auto vmbr0
iface vmbr0 inet manual
        bridge-ports ens1f0
        bridge-stp off
        bridge-fd 0

auto vmbr1
iface vmbr1 inet static
        address 172.16.1.78/24
        bridge-ports bond0
        bridge-stp off
        bridge-fd 0

and ip add :

Thanx. So why you use

Code: 
auto vmbr0v5

iface vmbr0v5 inet static

in configuration?
 
@m3a2r1 as an alternative you could also take the second example in the Docs. The one that uses vmbr0.5 instead of vmbr0v5.

This can be achieved purely via the GUI.

Configure vmbr0 to be VLAN aware and then create a new VLAN interface, called vmbr0.10 in your case.
 
I've configured with vlan, not vlan aware so I didn't mention second method (vmbr0.5) :)
Thank you for explanation.
 
If I change vmbr0v10 to vmbr0.10 I got error while networking restart: mtu less than device minimum .
What I should change?
 
Can you post the config the way you had it with vmbr0.10?
 
I've only changed vmbr0v10 to vbr0.10 in /etc/network/interfaces and restarted the networking service.

I know the reason, I've changed in /etc/network/interfaces but I didn't know that it changes linux bridge to linux vlan. I should remove bridge_stp/bridge_ports/bridge_fd settings from this section and it works. So I can set linux vlan with interface name not vmbrX.vlan and ip address and it should work too.

IMHO naming linux vlan like a bridge (starting with vmbrX) is useless and misleading because I can't assign vlan to vm. After all I need to create "real" linux bridge and add this "like a bridge" vlan to it.
