[j-nsp] tagged traffic on EX access port

[Christopher Hartley]

Add to that, you can use a native vlan.
... unit 0 family ethernet-switching native-vlan-id # You can use the symbolic name, too.
... and when you configure the vlan, if you want an RVI, use
set vlans VLAN-NAME l3-interface vlan.{vlan_id}, then configure the
vlan subinterface:
set interfaces vlan.{vlan_id} family inet ...

port-mode trunk is the default in family ethernet-switching (which can only be
on unit 0).

You can also use vlan-tagging and multiple units with distinct vlan-ids,
but you cannot also switch that vlan if you use that method - and all
vlans would need to be tagged.

I don't know whether this answers the original question?

This is the right way to configure 802.1Q trunks on EX'es.

For example, from an EX4200:

------------------------------------------------------
jof at ex1.sfo2> show configuration interfaces xe-0/1/0 
unit 0 {
    family ethernet-switching {
        port-mode trunk;
        vlan {
            members [ foo bar ];
        }
    }
}
------------------------------------------------------
