105 -z z_level
106 Configure compression level to z_level. 0 is disabled (no com‐
107 pression), 9 is highest compression.
108
110 Convert the cflowd file flows.cflowd to the flow-tools file flows.
111 Store as Version 5 with compression level 5.
112
113 flow-import -V5 -z5 -f0 < flows.cflowd > flows
114
116 Convert the ASCII CSV data in flows.ascii to flow-tools format. The
117 ASCII data must include all fields represented by 0xFF31EF in the order
118 listed above. Store as Version 5 with no compression.
119
120 flow-import -z0 -f2 -m0xFF31EF < flows.ascii > flows
121
123 The pcap format is a hack.
