How can make netflow for the following information:
Netflow Data Export enabledExporting flows to 10.16.16.2 (3322)Exporting flows from 10.16.16.15 (61111)Version: 5Layer2 flow creation is enabled on vlan 1,108-112Layer2 flow export is enabled on vlan 1,180-190Include Filter not configuredExclude Filter not configured
Juniper QFX5100 do not support Netflow, it just supports sFlow.
Here are some sites where you can check the sFlow configuration:

Thanks for reply , but still not found how can make it per vlans other than per interfaces ??
I suppose that you have a similar Cisco config like this:
ip flow ingress layer2-switched vlan <vlans>ip flow export layer2-switched vlan <vlans>
This is not possible with sFlow. If you have vlan interfaces (or irb interfaces, it's the same, just another name) on QFX, then you can specify these virtual interfaces. But it is not possible to specify pure vlans for layer2-switched traffic.
I am afraid that sflow does not support vlan interfaces or vlan sampling, please see this article :
NOTE: You cannot enable sFlow technology on a Layer 3 VLAN-tagged interface.NOTE: You cannot enable sFlow technology on a LAG interface. sFlow technology can be enabled on the member interfaces of the LAG.
If this solves your problem, please mark this post as "Accepted Solution". If you think that my answer was helpful, please spend some Kudos.
