 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?
