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

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

1005 Flow-Tools tagged version 5
-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
