Product guide

Network Access Control of hosts is regulating access to network resources based on host System

Health level (Standard/ DHCP NAC), identity of the user logged into the host (IBAC), or both. The

Sensor also provides the Hybrid NAC functionality where a host is first subjected to DHCP-NAC and

then Standard NAC at different ports of the same Sensor. For more information on the NAC

functionality and configurations of the Manager, see the NAC Administration Guide.

Throughout this guide the terms, 'Sensor' and 'M-1250/M-1450' refer to the M-1250 or the

M-1450 Sensor in general.

Physical description of the M-1250/M-1450 Sensor

The M-1250/M-1450 Sensor is equipped with eight Fast Ethernet ports (or interfaces). M-1250 can

monitor up to 100 Mbps, and M-1450 can monitor upto 200 Mbps of aggregated traffic respectively.

The M-1250/M-1450 Sensor can monitor four 10/100/1000 Mbps Ethernet segments in full-duplex

mode (tap or in-line), and eight segments in half-duplex mode (monitoring SPAN ports or hubs).

Ports on the Sensor

The M-1250/M-1450 Sensor is a one rack-unit (1RU) box equipped with the following ports:

1 RJ-45 10/100/1000 Management port (1)

2 RJ-45 Response port (1)

3 RS-232C Console port (1)

4 RS-232C Auxiliary port (1)

5 RJ-45 10/100/1000 Ethernet Monitoring ports (8)

7 Power supply A (1)

Figure 1-2 M 1450 Sensor back panel

One 10/100/1000 Management port, which is used for secure communication with the

Manager server. Communication between the Sensor and the Manager server uses secure

channels; these channels provide link privacy using encryption and mutual authentication between

Sensors and the Manager using public key authentication. You assign an IP address to this Ethernet

port during installation.

One Response port, which, when you are operating in the SPAN mode, enable you to inject

response packets back into your network, for example, through a switch or router. The Response

port is also used in the tap mode.
