Configure the UDP Input

QUESTION

How can NetObserv Flow’s flow port be changed?

ANSWER

NetObserv Flow receives packets containing flow records using UDP. There are three configurable parameters:

Parameter	Description
EF_FLOW_SERVER_UDP_PORT	The UDP port which NetObserv Flow listens to for Netflow/IPFIX/sFLOW packets
EF_FLOW_SERVER_UDP_IP	The IP address the UDP socket is bound to on NetObserv Flow
EF_FLOW_SERVER_UDP_READ_BUFFER_MAX_SIZE	The UDP receive buffer for the system. If this value exceeds the maximum allowed buffer size (net.core.rmem_max on Linux), the maximum allowed size is used.

Refer to the Configuration Reference for additional details.
