Cable the Sensor to monitor in in-line mode

In-Line mode requires that you use a pair of Sensor ports as described in the section, How to use peer ports.
In case the Sensor fails, the Sensor's internal 10/100/1000 ports fail-open or fail-close, depending on how the
ports are configured. Note that in M-1250/1450 Sensors, dongles are not required for fail-close operation. The
Sensor 10/100/1000 ports support Auto-MDIX.
Task
Plug a Cat 5/Cat 5e cable into a monitoring port, for example port 1A.
1
See Cable types for routers, switches, hubs, and PCs to determine which cable type to use with which type of
network device.
Plug a Cat 5/Cat 5e cable into the corresponding peer port.
2
If you had used 1A in step 1, then the corresponding peer port is 1B.
Connect the other end of each cable to the network devices that you want to monitor.
3
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.

Cable the Sensor to monitor in SPAN or hub mode

When you monitor in SPAN or hub mode, you can use single ports.
Task
Plug a Cat 5/ Cat 5e cable into one of the monitoring ports.
1
Connect the other end of the cable to the SPAN port or the hub.
2
See Cable types for routers, switches, hubs, and PCs to determine which cable type to use with which type of
network device.

About connecting Sensors for fail-over

Fail-over requires connecting two identical Sensors of the same model and same software version through an
interconnection cable or cables. Previously, the creation of Sensor fail-over pair was allowed only if all the
primary Sensor's monitoring port pairs were in in-line mode. Now, the flexibility to create a fail-over pair even if
McAfee Network Security Platform

Cabling Sensors for in-line mode requires a brief network interruption as you insert it in the flow of network
traffic. To avoid extended network downtime, you should cable a Sensor for in-line mode after you have
completed all other configuration tasks.
