Defining the Network Security Platform Failover Pair

Once McAfee

Network Security Sensors (Sensors) are known to be working

independently, we are ready to define a failover Pair. It is by way of the failover Pair

configuration that we ensure the Sensors share flow information under normal conditions

and also fail over as required.

In Figure Failover Pair creation, we have specified the Sensor model in question (I-4010),

named the Failover Pair, FO-Pair-4010, and selected the two intended Sensors:

Figure 15: Creating a Failover pair

Again, the one important consideration is that the current configuration of “primary” Sensor

will be copied over that of the “secondary” Sensor during the Pair creation process.

Note: The creation of a failover pair happens in real time. There is no need to

explicitly update the configuration.

When it comes to scanning roles, however, you can safely ignore the terms Primary

Sensor and Secondary Sensor here. Remember that both Sensors are always scanning

actively.
