[c-nsp] Netflow performance

[Manuel García Montero]

Hi,

Any advice in how netflow can affect the performance in a 6509? currently
the 6509 provides wccp (8 squids cache farm), with 40 MB of ram used
(366.9MBytes free), cpu stable at 1-2%, and supports ~500Mbps of
throughput ...

I was planning the following typical config (i can attach the rest of the
config if needed)

    mls netflow
    mls aging normal 60
    mls aging long 64
    mls flow ip interface-full
    mls nde sender version 5
    mls nde interface

    ip flow-export source IP_Router
    ip flow-export version 5 peer-as
    ip flow-export destination Collector_IP Collector_Port
    ip flow-aggregation cache source-prefix
      mask source 255.255.255.0


with C Class  aggregation in order to reduce flows size ¿is this premise
true?

Thanks.
