Simple NetFlow server configuration for ISP

This page describes a simple connection between Trisul NetFlow Server and an ISP Gateway router/switch. We use Cisco ASR as a sample device.

Key features:

- Using a public IP for the NetFlow server - Using ACL to restrict access - Using a separate IP for the DRAC (Remote management)

Diagram

The scenario is very simple.

We allocate a free public IP with /31 (point to point) and assign one to the port and another to the NetFlow server.
