Identifying the Sensing Interfaces
If you want to take advantage of the device's automatic bypass capability, you must connect two
interfaces vertically (interfaces 1 and 2, 3 and 4, 5 and 6, or 7 and 8) to a network segment. Automatic
bypass capability allows traffic to flow even if the device fails or loses power. After you cable the
interfaces, you use the web interface to configure a pair of interfaces as an inline set and enable bypass
mode on the inline set.
Firepower 7110 and 7120
The Firepower 7110 and 7120 are delivered with eight copper port sensing interfaces, or eight fiber port
sensing interfaces, each with configurable bypass capability. The following illustration of the front of
the chassis indicates the location of the sensing interfaces.

You can use these connections to passively monitor up to eight separate network segments. You can also
use paired interfaces in inline or inline with bypass mode to deploy the device as an intrusion prevention
system on up to four networks.
If you want to take advantage of the device's automatic bypass capability, you must connect either the
two interfaces on the left or the two interfaces on the right to a network segment. Automatic bypass
capability allows traffic to flow even if the device fails or loses power. After you cable the interfaces,
you use the web interface to configure a pair of interfaces as an inline set and enable bypass mode on
the inline set.
