Manage Network Segments
Manage network segments in IoT Security to properly learn devices and attributes
that use overlapping IP addresses.
In some instances, you may need to update or delete network segments for
IoT Security to properly learn about
devices with overlapping IP addresses.
For example, if you redeploy firewalls or add firewalls to a new site, update your
network segments to ensure that the traffic maps to the correct devices.
Whenever you change the firewalls assigned to a network segment, or change the
network segment's site assignment, reset the network segment. If you don't reset the
network segment, device attributes and behaviors learned from new traffic may be
associated with different devices previously learned through the network segment.
When you no longer need a network segment, delete the network segment to ensure that
attributes and behaviors get associated with the correct devices.
When you reset or delete a network segment, all devices and attributes learned
through the network segment assignment are deleted from the assets inventory.
Devices and attributes must be relearned from traffic through the updated
network segments.
Follow these procedures to manage network segments:
Update the Assigned Firewalls
- Navigate to .Click on the name of the network segment that you want to update to bring up the Edit Network Segment dialog box.In the Firewall field, add or remove firewalls.You can search by a firewall's serial number and name, or use the drop-down selector. The drop-down selector shows if firewalls are assigned to a network segment or not, including the network segment you're editing. If you select a firewall that is assigned to a different network segment, it's removed from its existing network segment after saving the configuration. There must be at least one firewall assigned to the network segment.

- Navigate to .Click on the name of the network segment that you want to update to bring up the Edit Network Segment dialog box.In the Assigned to Site (optional) field, select or create the new site that you want to assign the network segment to.Select or creating a new site replaces the existing site assignment in the Assigned to Site (optional) field.
