101 Populating the topology database
Adding nodes and objects
Be sure to delete the template (0.0.0.0/0) from the list.
Caution: You must replace the default entry (0.0.0.0/0) in the Networks tab
with valid monitored networks in CIDR format before starting a sensor on
the interface. If you fail to take this step, the database can fill with invalid
data and result in a loss of detection and alerting functionality.
7 Click OK to add the in-line pair object to the topology.
Note: Click Topology > Save Changes before quitting the Network Security
console. You will lose any unsaved changes when you exit.
See “Deleting objects” on page 81.
About router objects
Routers store data packets and forward them along the most expedient route
between hosts or networks. Symantec Network Security monitors this
connection. Add an object to the topology tree to represent each router that you
want Symantec Network Security to monitor.
If you plan to enable the TrackBack response action to read flow data exported
from routers, you must add router objects and corresponding interface objects
to the topology tree.
