with your inline mode deployment.

Verify that traffic is flowing through the Sensor

For any inline Sensor, you can look at the statistics for each Sensor port to confirm that
traffic is properly flowing through it, by launching the Threat Analyzer.
Note: For step-by-step procedures on verifying how to verify traffic is flowing
through the Sensor, see the

Verify failover pair creation success

If you have configured a failover pair prior to cabling the heartbeat connection, you will
notice Failover peer status errors appearing on the
the heartbeat connection. These messages will not appear if the two communicate
properly.
The status of the communication between the Sensors can be monitored on the
View Details
page of the Manager interface or directly from the CLI of either Sensor.
The Network Security Sensor command line interface (CLI) is a valuable tool for verifying
correct configuration as well as diagnosing possible problems.
Note: See full list of Sensor CLI commands in the
