Selam,

Router uzerinde asagidaki komutları kullanarak, tekrar yapmayı deneyebilirsin.  

ip flow-export source Ethernet1/0

ip flow-export version 5

ip flow-export destination x.x.x.x 2055 (Burada ip adresi olarak, netflow programının kurulu olduğu ve netflow bilgilerini export edecegin makinenın ip adresini gostereceksin.) Ayrıca router uzerinde snmp'nin konfigure edilmesi gerekiyor.

!

interface Ethernet1/0

ip route-cache flow

Kolay Gelsin,

router#sh run | inc flo

ip flow-export source FastEthernet0/1.1

ip flow-export destination 10.9.1.200 2055  

Musteri 10.9.1.200 adresinde UDP 2055 acik bisekilde NTOP sniffer'i ile

bilgi almaya calisiyor ama routeri control ettigimde hic bir paket

kulanmadigini ve debug ip flow export ile gozlemlemek istedigimde ise

Router #sh ip flow exp

Flow export v5 is enabled for main cache

  Exporting flows to 10.9.1.200 (2055)

  Exporting using source interface FastEthernet0/1.1

  Version 5 flow records, peer-as

  0 flows exported in 0 udp datagrams

  0 flows failed due to lack of export packet

  0 export packets were sent up to process level

  0 export packets were dropped due to no fib

  0 export packets were dropped due to adjacency issues

  0 export packets were dropped due to fragmentation failures

  0 export packets were dropped due to encapsulation fixup failures    

Router'in nekadar siklikla bilgi gondermesini gerektigini ya da nerede

yanlis yaptimi soyleyebilecek olan varmidir
