Flows on the 7600 can come from two different sources - CPU and Hardware/MLS.

CPU switched packets will cause, well "CPU flows", and those respect the
settings of "ip flow ingress" on the interfaces.

Hardware/MLS switched packets will cause flow records on *all* interfaces,
and so you see traffic for most of the data flowing through your 7600.

As a workaround, you need to filter by ifindex on the netflow collector.

(To be precise: the above is true up to 12.2(18)SXF.  As far as I understand,
in 12.2(33)SXH and in SR<something>, the MLS flow entries will actually be
filtered according to the "ip flow ingress" settings on the interfaces, and
thus you won't see unexpected flows.  I have not yet tried either version,
but have read it in the release notes...).
