qfx don't show subinterface

Hi,

on a qfx5100 I configured some subinterface

set interfaces xe-0/0/46:0 vlan-tagging
set interfaces xe-0/0/46:0 encapsulation flexible-ethernet-services
set interfaces xe-0/0/46:0 unit 101 description GLOBAL
set interfaces xe-0/0/46:0 unit 101 traps
set interfaces xe-0/0/46:0 unit 101 vlan-id 101
set interfaces xe-0/0/46:0 unit 101 family inet address 10.9.30.27/31
set interfaces xe-0/0/46:0 unit 401 description CUST
set interfaces xe-0/0/46:0 unit 401 traps
set interfaces xe-0/0/46:0 unit 401 vlan-id 401
set interfaces xe-0/0/46:0 unit 401 family inet address 10.9.30.25/31
set interfaces xe-0/0/46:0 unit 850 description ENT
set interfaces xe-0/0/46:0 unit 850 traps
set interfaces xe-0/0/46:0 unit 850 vlan-id 850
set interfaces xe-0/0/46:0 unit 850 family inet address 10.9.30.241/29

but If I give "show interface terse" I don't see that subinterfaces but only:

xe-0/0/46 up up
xe-0/0/46.16386 up up

the physical interface is up.

Why ?

 I expect to see something like:

xe-0/0/46:0.101  up    10.9.30.27/31

xe-0/0/46:0.401 up     10.9.30.25/31

xe-0/0/46:0.850  up    10.9.30.241/29
