    NetFlow Stopped Exporting from a 6509

    shaochen

      We have this 6509 in a high school and it stopped sending netflow since Oct. 14. Hopefully some one can help me to troubleshoot it to see why.

       

      I have captured the following pieces to go through the netflow settings on this switch. Let me know if I need to provide additional information.

       

      When I telnet to 10.x.254.1 and did "show ip flow export"

       

      Flow export is enabled

       

        Exporting flows to 10.1.1.248 (2055)

       

        Exporting using source interface Vlan254

       

        Version 5 flow records

       

        24422797 flows exported in 987830 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

       

        0 export packets were dropped enqueuing for the RP

       

        0 export packets were dropped due to IPC rate limiting

      Trying to find out why it stopped exporting, and I am having difficult time to understand from iOS and CatOS on the same core switch.

       

      According to "show ip flow export" from 10.x.254.1, the source is vlan254 and port 4/2 is set for vlan254
