Cable types for routers, switches, hubs, and PCs

This section describes the types of cables that you require to connect the Sensor to other network

devices:

• Use a crossover Ethernet RJ-45 cable to connect a router port to the 10/100/1000 copper SFP

Monitoring ports.

• Use a straight-through Ethernet RJ-45 cable to connect a switch/hub port to 10/100/1000 copper

SFP Monitoring ports.

• Use a crossover Ethernet RJ-45 cable to connect a router port to PC to the Sensor Management

port.

You should also use a crossover Ethernet RJ-45 cable to connect a PC to the Sensor monitoring port.

Cable for in-line

The Gigabit Ethernet ports fail-close, meaning they stop the flow of traffic if the Sensor fails. To allow

traffic to flow uninterrupted, you must use special hardware and cable the Sensor for fail-open

functionality. For instructions, see the section later in this chapter.

This section provides the steps to connect the Sensor's Gigabit Ethernet ports so they fail-close.

Task

Plug the cable appropriate for use with your Gigabit Ethernet into one of the Monitoring ports, for

example, 1A.

Plug another cable into the peer of the port used in Step 1.

Connect the other end of each cable to the network devices that you want to monitor.

For example, if you plan to monitor traffic between a switch and a router, connect the cable

connected to 1A to the switch and the one connected to 1B to the router.

Connect the cables for tap mode

To deploy the Sensor in tap mode, you must use a Sensor's Gigabit Ethernet Monitoring port pair with

a third-party external tap.
