4230 Sensor

4230 Sensor

The 4230 Sensor is one of the older models in the 4200 series. In fact, the Cisco IDS 4230 sensor was end-of-sale (EOS) as of July, 2002. While software and hardware support will continue for a limited time, this device is no longer available from Cisco. Instead, Cisco recommends the use of the 4235 sensor based on improved performance, size, and port density. We'll discuss the 4230 sensor in this chapter because the hardware is still included in the CSIDS 9E0-100 exam.

The 4230 sensor is a dual Pentium III-based sensor with two fixed 10/100Base-T ports. Like the 4210, one is reserved for monitoring, while the other is intended for command and control access. The 4230 is capable of handling 100 Mbps, which makes it a good choice for Fast Ethernet environments. At four RU, the 4230 is a larger device than the other 4200 series sensors.
