The VLAN-aware checkbox is a new addition that allows Proxmox to act as a trunk in a switch that will pipe multiple VLANs over one connection. Although it is not important to enable it, however, it is a new way of handling VLANs on the bridge. For example, if we need to implement 10 VLANs, we will need to create 10 virtual bridges in the traditional Linux bridge way.

The following shows a basic example configuration of a traditional Linux virtual bridge for 10 VLANs:

auto vlan0iface vlan0 inet manual        vlan_raw_device eth0auto vmbr0iface vmbr0 inet manual bridge_ports ...
