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.
