Port mirroring // RSPAN with Juniper QFX switch as a transit switch

Hello,

I have to implement port mirroring, with RSPAN to collect and monitor the traffic from a cisco switch (1) to another cisco switch (2).

But in between there's a Juniper QFX switch (the one I am calling the 'transit switch').

So my source will be a cisco switch (1) port, my rspan vlan is the vlan 35, then I'll go through the Juniper QFX, and the final destination is another cisco switch (2), from which I will collect the remote traffic.

I'd like to know what is the configuration to put in the QFX, so that it will be able to collect and forward that traffic from the interface ge-1/0/46 [input interface connected to the cisco (1)]  to the interface ge-0/0/9 [output interface connected to the cisco (2)].

The traffic will be transfered in a vlan trunk, with many vlans, and I'd like to collect the traffic from the vlan 35 only.

     CISCO (1)                                                                           JUNIPER QFX                                                                     CISCO (2)

RSPAN VLAN 35      =trunk vlan35=>  int ge-1/0/46  RSPAN VLAN 35(?)   int ge-0/0/9  =trunk vlan35=>     RSPAN VLAN 35

Thanks for your help!
