I am wanting configure QoS on my EdgeRouter but am having trouble assigning the policy to the interface.

Examples on the web use eth0 as the WAN interface, but I am on fibre so my WAN interface is a pppoe interface with a VLAN as it's parent.

Physical interface:   eth0

VLAN interface:       eth0.10

PPPoE interface:      pppoe0

If the WAN interface was eth0 with no VLAN or PPPoE the command would be:

set interfaces ethernet eth0 traffic-policy out UpStream

If the WAN interface was PPPoE using eth0 as it's parent, but with no VLAN the command would be:

set interfaces ethernet eth0 pppoe 0 traffic-policy out UpStream

But I can't find how to make it work when the PPPoEs' parent is a VLAN.

Any help would be greatly appreciated.

EDIT: In the above commands "UpStream" is the name of the policy I have created.
