  1. Hi Hamood,

    You can use a loopback and yes, that would be a good idea because of this reason.


  2. Thank you Rene.

    I just wanted to ask what’s the cpu impact of using netflow on lets say routers 7200 series, 3800 and 3900 series? Is it safe to run it on production network?

  3. Hi,
    Can you explain about netflow vs sflow and how to implement sflow on cisco isr routers ?

  4. Hello Rene,

    I was reading an article about Netflow specific to IOS XE. I read a few terms called :

    1. Netflow Monitor
    2. Flow record
    3. netflow exporter

    can you please help in understanding how they are separate from each other ?


  5. I think a typo here see below you say “Can`t” I think you mean “can”??

    One of the things we can’t do with those tools is tracking all flows in our network. A flow is a stream of packets that share the same characteristics like source/destination port, source/destination address, protocol, type, service marking, etc.

    NM you was talking about SNMP and NBAR not Netflow I see now. my bad.
