Topology Database 49 About the network topology ■ Routers: Objects that represent devices that store data packets and forward them along the most expedient route. Symantec Network Security monitors this connection between hosts or networks. ■ Interfaces: Objects that represent boundaries across which separate elements can communicate. Interfaces provide the point of contact between Symantec Network Security and routers. ■ Smart Agents: Objects that represent the entry point for event data from Symantec Decoy Server, Symantec Network Security Smart Agents, and other third-party sensors. ■ Managed network segments: Objects that represent subnets in which the network devices and interfaces reside. The Network Security console automatically creates a network segment object for each unique subnet. ■ Interfaces: Objects that represent boundaries across which separate elements can communicate. Interfaces provide the point of contact between Symantec Network Security and your network devices. ■ Monitoring interfaces: Objects that represent dedicated ports that mirror incoming or outgoing traffic on a software or appliance node. ■ In-line pairs: Objects that represent pairs of interfaces on a 7100 Series appliance node that are directly in the network traffic path. For a given flow, one interface connects to inbound traffic and the other to outbound traffic. Only in-line pairs can be configured to block malicious traffic. ■ Interface groups: Objects that represent groups of two to four interfaces on a 7100 Series appliance node that share a common sensor. Interface groups are used to monitor asymmetrically routed network environments, and are configurable only on 7100 Series nodes. Viewing node status The Network Security console displays an object in the topology tree representing devices and interfaces in the network. When a software or appliance node experiences a process failure of any kind, the Network Security console displays the node with a red X, called the Node Status Indicator. This signifies that Network Security processes or connectivity to the network has failed. To view node status ◆ See the Node Status Indicator for the software or appliance node.

Viewing node status
The Network Security console displays an object in the topology tree
representing devices and interfaces in the network. When a software or
appliance node experiences a process failure of any kind, the Network Security
console displays the node with a red X, called the Node Status Indicator. This
signifies that Network Security processes or connectivity to the network has
failed.
