Source interface for Sflow on QFX10002

[ Edited ]

Is it possible to use another source interface than em0 in the SFLOW configuration?

 

I have created a separate routing-instance for flows, and I would like to use the IRB assigned to this routing-instance as the source interface.

 

As of now, the flow is crashing in to the firewall on the management network as it is beeing sourced by em0, even though I have specifically set a source-ip belonging to the Flow IRB interface.

Check this link

7. Specify the source IP address to be used for sFlow datagrams:

[edit protocols sflow]

user@device# set source-ip ip-address

Both links are referring to EX-switches. And I'm not interested in changing the source IP, I want to change the interface thats used to source the flow.
