In this article we will discuss on how to configure security flow traceoption to capture specific host traffic flow.

If you have a source-ip and destination-ip and matching protocol traffic you can use below example.

lab@router-re0# show security flow

traceoptions {

  file flowd-trace size 100m files 5 world-readable;

  flag all;

  packet-filter App_trafic {

    protocol udp;

    source-prefix <src_ip>;

    destination-prefix <dst_ip>;

  }

}
