Is your switch sending real traffic to the collector?

  Hello,
  
  Does the Extreme switch support outbound sFlow capture? I know that some
  Foundry devices only do inbound. Check the manual for that Extreme switch
  to see if it's inbound only.

     Hi,
    
    Recently some of our customers reported that they did not get any OUT
    traffic information. We analyzed the SFlow packet and found that OUTPUT
    port is zero in all flows. It happened only on Extreme switches. I have
    attached the packet dump with this. Can any one please tell me whether is
    it a bug or am I missing something?
