I want to filter the netflow records by
engine_id, I have tried
nfdump -r <FILE> engine_id 10
nfdump -r <FILE> -s engine_id 10
But, it is not working.
What do I do wrong?
Here you find the manual for
I don't know we can filter with engine id in netflow records. I found this LINK. My goal is to differentiate the input OVS port in different servers. From that article, we can differentiate the input OVS ports with combination of
In that Article
"There is another use case for Engine ID. As I already explained that OVS uses OpenFlow port number as an In/Out interface number in NetFlow flow record. Because OpenFlow port number is a per bridge unique number, there is a chance for these numbers to collide across bridges. To get around this problem, you can set “add_to_interface” to true."
“When this parameter is set to true, the 7 most significant bits of In/Out interface number is replaced with the 7 least significant bits of Engine ID. This will help interface number collision happen less likely.”
