I followed this to do the configuration.
https://pve.proxmox.com/wiki/Network_Model

And this is my interfaces file

auto lo
iface lo inet loopback

auto eno2
iface eno2 inet manual

auto vmbr0
iface vmbr0 inet static
address 18.23.5.10
netmask 255.255.255.0
gateway 18.23.5.254
bridge_ports bond0
bridge_stp off
bridge_fd 0


auto bond0
iface bond0 inet manual
slaves eno2
bond_miimon 100
bond_mode 802.3ad


auto vlan2002
iface vlan2002 inet manual
vlan_raw_device bond0

auto vlan20
iface vlan20 inet manual
vlan_raw_device bond0

Even ip a looks fine

I have also looks at dmesg, nothing seems wrong as well.
I am in lost.
Would you please help me?
Thanks

you don't need to define vlan interfaces in /etc/network/interfaces

if you define vlan tag in vm configuration, proxmox will create the bond0.vlan interface and a vmbr0v[vlan] bridge for you.

Thanks, is there any diferent between the network setup of a cluster and standalone?
Because last time i setup a cluster, seems declear the vlan on the HV node is ok, but this time is not.
Anyway, it is ok now, thank you aderumier!
