Configure the UDP Input
QUESTION
How can the flow collector’s flow port be changed?
ANSWER
The ElastiFlow Unified Flow Collector receives packets containing flow records using UDP. There are three configurable parameters:
| Parameter | Description |
|---|---|
| EF_FLOW_SERVER_UDP_PORT | The UDP port which the flow collector listens to for Netflow/IPFIX/sFLOW packets |
| EF_FLOW_SERVER_UDP_IP | The IP address the UDP socket is bound to on the flow collector |
| 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.
