Microolap EtherSensor requires a connection to a network of network control and interception  interfaces.

The control interface is a standard network interface with a set TCP/IP address, subnet mask and the default router address, if required.

When setting up Microolap EtherSensor, it is recommended to specify DNS servers that support reverse name resolution (from IP address to the hostname) of the LAN hosts. This allows detection of names of the hosts participated in the connection, host TCP/IP addresses are assigned using DHCP.

Data received from DNS servers are cached, which decreases any added DNS server workload. Caching settings are set up using EtherSensor Configuration Editor utility (ethersensor_console.exe).

The control interface connection speed should be enough to pass all intercepted messages without accumulating them on the sensor. You can use 100/1000/10000 Mbit/s network interfaces.

When configuring the network control interface, account for Microolap EtherSensor special settings, which apply when filtering recognized data sent through the network control interface. For more information on these settings, refer to "EtherSensor EtherCAP Service" section.
