Configure the UDP Input
QUESTION
How can the Unified Flow Collector’s flow port be changed?
ANSWER
The 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 on which the Unified Flow Collector listens for Netflow/IPFIX/sFLOW packets |
| EF_FLOW_SERVER_UDP_IP | The IP address the UDP socket to which the Unified Flow Collector is bound |
| 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.
