flow-receive: Receive flow data with the NetFlow protocol.
NAMEflow-receive - Receive flow data with the NetFlow protocol.
The flow-receive utility is used to receive flows in NetFlow format. When the remoteip is configured only flows from that exporter will be processed, this is the most secure and recommended configuration. When the localip is configured flow-receive will only process flows sent to the localip IP address. If remoteip is 0 (not configured) flows from any source IP address are accepted. Multiple non aggregated PDU versions may be accepted at once to support Cisco's Catalyst 6500 NetFlow implementation which exports from both the supervisor and MSFC with the same IP address and same port but different export versions. In this case the exports will be stored in the format specified by the -V flag or whichever export type is received first.
- -b big|little
- Byte order of output.
- -C Comment
- Add a comment.
- -d debug_level
- Enable debugging.
- Display help.
- -o file
- Write to file instead of the standard out.
- -S stat_interval
- When configured flow-receive will emit a timestamped message on stderr every stat_interval minutes indicating counters such as the number of flows received, packets processed, and lost flows.
- -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.
Listen on port 9800 on any local interface for exports from IP address 10.0.0.1, store the exports in flows
