1.4.2. Hardware specifications

It is very difficult to recommend optimal configuration, because good server performance depends on the amount of incoming data. Generally, there is an advantage in having adequate RAM memory and fast access to disc(s). The specification of your system depends on the number of routers sending network information to the CFI, as well as the level of actual router traffic.

Apart from the minimum hardware requirements set out below, is necessary to ensure that CFI should run on a dedicated PC or Server. The software is processor-intensive and in the case of very high loading (busy processor) it can cause problems in collecting NetFlow.

Manufacturer devices supporting CFI software are: Cisco Systems, Juniper, Extreme Networks and 3COM.

CFI supporting devices series (Cisco routers and/or switches): 1400, 1600, 1700, 2500/2600, 3600, 4500/4700, AS5300/5800, 7200/7500, Catalyst 4500, Catalyst 5000/6500/7600, ESR 10000, GSR 12000.

Please, ask your hardware supplier if your devices support NetFlow export.
