regardless of the source of the packet. I’m unsure if my collector understands this when collecting from multiple sources on the same destination port (nfdump/nfsen). I’m going to have to check into it… and allow sflow traffic from all interfaces of my XMR’s
through the firewall where my collector sits. Not ideal, but seems to be all I have to work with until 5.3.<o:p></o:p></span></p>

<br>
At least on a fastiron: <br>
<br>
sflow agent-ip <br>
<br>
This option didn't appear until more recent ironware releases though... <br>
