Introducing the Sensor
After being installed at key points in the network, the appliance monitors and performs real-time analysis
of network traffic by looking for anomalies and misuse based on an extensive, embedded signature
library. When the system detects unauthorized activity, appliances can terminate the specific connection,
permanently block the attacking host, log the incident, and send an alert to the manager. Other legitimate
connections continue to operate independently without interruption.
Appliances are optimized for specific data rates and are packaged in Ethernet, Fast Ethernet, and Gigabit
Ethernet configurations. In switched environments, appliances must be connected to the SPAN port or
VACL capture port of the switch.
The Cisco IPS 4200 series appliances provide the following:

Connecting an Appliance to a Terminal Server

A terminal server is a router with multiple, low speed, asynchronous ports that are connected to other
serial devices. You can use terminal servers to remotely manage network equipment, including
appliances.
To set up a Cisco terminal server with RJ-45 or hydra cable assembly connections, follow these steps:
Connect to a terminal server using one of the following methods:
Step 1
OL-18504-01
Protection of multiple network subnets through the use of up to eight interfaces
Simultaneous, dual operation in both promiscuous and inline modes
A wide array of performance options—from 80 Mbps to multiple gigabits
Embedded web-based management solutions packaged with the sensor

Chapter 4, "Installing the IPS 4270-20"
The appliance is not a general purpose workstation.
Cisco Systems prohibits using the appliance for anything other than operating Cisco IPS.
Cisco Systems prohibits modifying or installing any hardware or software in the appliance that is
not part of the normal operation of the Cisco IPS.
For terminal servers with RJ-45 connections, connect a 180 rollover cable from the console port on
the appliance to a port on the terminal server.
For hydra cable assemblies, connect a straight-through patch cable from the console port on the
appliance to a port on the terminal server.
