[c-nsp] Netflow issue

[Hank Nussbacher]

We used to collect full unsampled Netflow from two 7613 routers.  Both ran
12.2(18)SXF11 and all was well.

We continue to get flow data as follows from the 12.2(18)SXF router:
Flow export v5 is enabled for main cache
   Exporting flows to xxx.139.197.76 (9800) xx.229.0.7 (8888)
   Exporting using source interface Loopback0
   Version 5 flow records, origin-as
   35057147 flows exported in 1168572 udp datagrams

We upgraded the other 7613 to 12.2(33)SRE6 - and most of the flow data no 
longer appears in our collector.  Yet:
gp1#sho ip flow export
Flow export v5 is enabled for main cache
   Export source and destination details :
   VRF ID : Default
     Source(1)       xxx.139.220.90 (Loopback0)
     Destination(1)  xxx.139.197.76 (9800)
   Version 5 flow records, origin-as
   28312144 flows exported in 943738 udp datagrams
It appears like we should be getting flow data but we are not.

We have a very simple Netflow setup.  On most GigE and 10GigE interfaces we 
have defined:
ip flow ingress
and globally we have defined:
ip flow-cache entries 120000
mls flow ip interface-full

This used to work pre-12.2(33)SRE.  Something must have changed that we are 
not aware of that needs to be defined.  Any ideas?

Thanks,
Hank
