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:

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.
2
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.
3
One RS-232C Console port, which is used to set up and configure the Sensor.
4
One RS-232C Auxiliary port, which may be used to dial in remotely to set up and configure the Sensor.
5
Eight 10/100/1000 Monitoring ports, which enable you to monitor eight SPAN ports or four full-duplex
tapped segments or four segments in-line. When the Sensor operates in the IPS mode, these ports operate
in stealth mode; that is, they have no IP addresses nor even a TCP/IP stack to respond to IPS detection
techniques. This renders them completely invisible to intruders. When operating in the NAC mode, the
monitoring ports can be assigned IP addresses. The monitoring ports for M-1250/M-1450 Sensor are 1A/1B,
2A/2B, 3A/3B and 4A/4B.
