[f-nsp] XMR sflow source-interface??

[Vinny_Abello at Dell.com]

Just an FYI - I've worked around this for now by using a different port for each XMR on my sflow collector. It's identifying each device by the port the sflow data is coming in on rather than the source IP now.

Yeah, unfortunately that doesn't exist in Ironware 5.1 on the XMR:

(config)#sflow ?
  destination        Set sflow datagrams export destination
  enable             Enable sflow services
  polling-interval   Set interface counters polling-interval
  sample             Set sample rate

I heard from someone else that this is planned for Ironware 5.3. I also was told that the packets themselves contain an identifier that the collectors can use 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.

Thanks everyone!

At least on a fastiron:

sflow agent-ip

This option didn't appear until more recent ironware releases though...
