[c-nsp] netflow & Sup32 with native IOS

[matthew zeier]

Is there a trick to get Netflow working on a Sup32 running native IOS?

I'm using ehnt to view top destination ASNs. I have the following config and 
am getting data sent, however, the traffic counts are far below what I'm 
actually pushing (>200Mbps).

For instance,

|---------------Dest----------------|
|----AS Name/Num----|-bw,% of total-|
  VZGNI-TRANSIT(19262)    174k;  39.00%
         KOMTEL( 8881)     13k;   2.93%
      <unknown>(28573)     12k;   2.64%
    CNCGROUP-BB( 4837)     11k;   2.51%
    ALTERNET-AS(  701)     11k;   2.49%


I can't tell if my config is wrong or there's some limitation of the Sup32. 
The bw figures are way low.

ip flow-export source Loopback0
ip flow-export version 5 origin-as
ip flow-export destination blah 4444


interface Port-channel1
