Network traffic interception doesn't require setting up the TCP/IP protocol stack and other protocols. This network interface captures packets to analyze their content. The traffic may come to this interface from a router mirror port, a hub or a network tap.

For normal work, it is required that the traffic on the interception interface contain all network packets, both from the server (RX) and the client (TX).

Warning!
For Microolap EtherSensor it doesn't matter whether traffic has VLAN tags or not. The network adapter driver removes these tags either way.

The interception interface bandwidth should exceed the incoming stream by at least 20%. This guarantees that the packets won't drop when captured on the network hardware, and that interception quality remains high.

The sensor can handle more than one interception interface on one server. The maximum number of these interfaces in the Microolap EtherSensor runtime environment is not limited; however, it depends on the performance of network interfaces and on the overall performance of the Microolap EtherSensor runtime environment (e.g., RAM size and CPU characteristics, etc.).
