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.
