[j-nsp] Problem with QinQ MPLS Service + Switch

Hi
I have MPLS network based on MX80 routers: r01, r02, r03

I need to establish MPLS Layer2 service with QinQ from r01:xe-0/0/0 to
r03:xe-0/0/1.300 (VLAN 300). Customer on r01 is directly terminated on MX80
And on r03 customer is terminated via Catalyst switch (sw01) on port
TenGig1/1/4 (VLAN300)

L2 service established fine (show l2circuit connections)
But service is not working.
Any idea why ?

Network diagram:

Customer --- xe-0/0/0-r01-xe-0/0/1
                             |
                 |
                 |
               xe-0/0/0
                  r02
               xe-0/0/1
                             |
                             |
                             |
                           xe-0/0/0
                              r03
                           xe-0/0/1.300

Customer -- TenG1/1/4-sw01-TenG1/1/3

My configuration:

r01:

xe-0/0/0 {
    flexible-vlan-tagging;
    mtu 9100;
    encapsulation flexible-ethernet-services;
    unit 300 {
       encapsulation vlan-ccc;
       vlan-id 300;
       input-vlan-map {
          push;
          tag-protocol-id 0x8100;
       }
       output-vlan-map pop;
       family ccc;
    }
}
protocols {
    l2circuit {
        neighbor 10.10.10.3 {
            interface xe-0/0/0.300 {
                virtual-circuit-id 300;
            }
        }
    }
}

r03:

xe-0/0/1 {
    flexible-vlan-tagging;
    mtu 9100;
    encapsulation flexible-ethernet-services;
    unit 300 {
       encapsulation vlan-ccc;
       vlan-id 300;
       family ccc;
    }
}
protocols {
    l2circuit {
        neighbor 10.10.10.1 {
            interface xe-0/0/0.300 {
                virtual-circuit-id 300;
            }
        }
    }
}


sw01:

interface TenGig1/1/3
 switchport mode trunk
 switchport trunk allowed vlan 300
!
interface TenGig1/1/4
 switchport mode dot1q-tunnel
 switchport access vlan 300
