Nexus 7000, F2-series lines cards and netflow

                   Hello,

  We recently refreshed our core switches, upgrading from Cat 6500/sup720 switches to Nexus 7000 Sup2 switches.  The Nexus switches have F2-series, 48 port 1/10G line cards installed.  When porting the confgs, I noticed that only sampled netflow is supported on the Nexus switches.  Is this a hardware limitation of the F2-series line cards?  Or is it a limitation of NX-OS (and will be addressed in a future code release)?  And how useful is sampled netflow?  Right now I really don't see the point in enabling it since at best only 1 in 4600 flows will be sampled.  Or am I doing something wrong?  Any insight welcomed.  Thanks.
