— Receive flow data with the NetFlow protocol.

utility is used to receive flows in NetFlow format. When
is configured only flows from that exporter will be
processed, this is the most secure and recommended configuration. When the
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
- -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

Listen on port 9800 on any local interface from any IP address, display the
received flows with flow-print.

It is not currently possible to convert between the aggregated formats (8.x) and
the non aggregated formats (1,5,6,7).
