Netflow/IPFIX/sFlow (UDP)
NetObserv Flow receives network flow records over UDP. This setting specifies the IP address of the interface on which the collector will listen.
EF_FLOW_SERVER_UDP_IP
- Valid Values
0.0.0.0
or any valid IP address to which the UDP socket can be bound.
- Default
0.0.0.0
(listen on all interfaces)
EF_FLOW_SERVER_UDP_PORT
The UDP port(s) on which the collector will create a socket to receive incoming packets. Multiple ports may be specified, separated by a comma. For example 2055,6343,4739
- Valid Values
- Any valid port number. Common values include:
2055
: the standard port for Netflow4739
: the standard port for IPFIX6343
: the standard port for sFlow9995-9998
: commonly use port numbers
- Any valid port number. Common values include:
- Default
9995
EF_FLOW_SERVER_UDP_READ_BUFFER_MAX_SIZE
The size, in bytes, of the UDP receive buffer that the UDP server will request be created by the operating system kernel when the socket is created. If this value exceeds the maximum allowed buffer size (net.core.rmem_max
on Linux), the maximum allowed size is used.
- Default
33554432
EF_FLOW_PACKET_STREAM_MAX_SIZE
Received UDP PDUs are queued prior to being processed by an available decoder. This value specifies the size of the queue as a quantity of PDUs.
- Default
4096 * EF_FLOW_LICENSED_UNITS
