About 7100 Series interfaces Each Symantec Network Security 7100 Series interface is a point of contact between the 7100 Series node and a network device. The node accesses traffic on the network device via the interface. There are three interface types available on a 7100 Series node: ■ Monitoring interface ■ Interface group ■ In-line pair A single interface that monitors network traffic copied to it from a network device. Also known as a passive mode interface. Monitoring interface objects are automatically generated when a node object is added. Two to four passive mode interfaces sharing a single sensor. Used in an asymmetrically routed environment. Two interfaces cabled into the actual network traffic path, and configured for in-line mode. Allows blocking of malicious traffic.
