Using Multiple Sensing Interfaces on a Managed Device

Using Multiple Sensing Interfaces on a Managed Device
The managed device offers multiple sensing interfaces on its network modules. You can use multiple
sensing interfaces on managed devices to:
•
•
•
•
Although each sensing interface is capable of receiving the full throughput for which the device is rated,
Note
the total traffic on the managed device cannot exceed its bandwidth rating without some packet loss.
Deploying multiple sensing interfaces on a managed device with a network tap is a straightforward
process. The following diagram shows a network tap installed on a high-traffic network segment.
In this scenario, the tap transmits incoming and outgoing traffic through separate sensing interfaces.
When you connect the multiple sensing interface adapter card on the managed device to the tap, the
managed device is able to combine the traffic into a single data stream so that it can be analyzed.
Note that with a gigabit optical tap, as shown in the illustration below, both sets of sensing interfaces on
the managed device are used by the connectors from the tap.
