NAME

       flow-import — Import flows into flow-tools from other NetFlow packages.

SYNOPSIS

       flow-import  [-h]   [-b  big|little]  [-d debug_level]  [-f format]  [-m mask_fields]  [-V
       pdu_version]  [-z z_level]

DESCRIPTION

       The flow-import utility will convert data from cflowd and ASCII CSV files into  flow-tools
       format.

OPTIONS

       -b big|little
                 Byte order of output.

       -d debug_level
                 Enable debugging.

       -f format Export format.  Supported formats are:

         0 cflowd
         2 ASCII CSV
         3 Cisco NFCollector

       -h        Display help.

       -m mask_fields
                 Select  fields  for  cflowd  and ASCII formats.  The mask_fields is built from a
                 bitwise OR of the following:

                 The default value is all fields applicable to the pdu_version.

       -V pdu_version
                 Use pdu_version format output.

       -z z_level
                 Configure compression level to  z_level.  0 is disabled (no compression),  9  is
                 highest compression.

EXAMPLES

       Convert  the  cflowd  file  flows.cflowd to the flow-tools file flows.  Store as Version 5
       with compression level 5.

         flow-import -V5 -z5 -f0 < flows.cflowd > flows

EXAMPLES

       Convert the ASCII CSV data in flows.ascii to  flow-tools  format.   The  ASCII  data  must
       include  all fields represented by 0xFF31EF in the order listed above.  Store as Version 5
       with no compression.

         flow-import -z0 -f2 -m0xFF31EF < flows.ascii > flows

BUGS

       The pcap format is a hack.
