Hi Phil,

I just mean netflow v9 field 61 Direction as specified in RFC3954.

0 means this flow is incoming, 1 indicates this flow is outgoing.

The %out and %in fields just says on which interface they
entered/leaved, however matching that on collector side to overall
incoming/outgoing traffic is much more difficult than assigning this on
the probe side.

Cheers,
Dani
