When monitoring the activity of devices in the industrial network, the application can automatically assign statuses to detected devices based on the obtained MAC- and/or IP addresses of devices. Statuses are assigned depending on the current asset management mode.
In learning mode, the application assigns a status of Authorized to all detected devices (this includes new devices as well as devices that were previously added to the devices table). If a status of Unauthorized was previously assigned to a detected device, its status is not changed.
In monitoring mode, the assigned status depends on whether the device that showed activity is known or unknown to the application. In this mode, statuses are assigned according to the following rules:
By default, if a device with a status of Authorized has not shown any activity in over 30 days and the device information has not changed during this time, a status of Archived is assigned to this device. You can disable automatic device status change to Archived when manually changing device status (for example, to prevent Authorized from automatically changing to Archived for rarely connected devices).
Cisco Switch connectors may automatically restrict network access for devices that have a status of Unauthorized. To avoid blocking necessary devices due to status changes, check the settings you defined for this connector type.
When devices with a status of Unauthorized appear in the devices table, you need to determine whether all of these devices are required for industrial process support. After making this determination, it is recommended to manually assign one of the following statuses to each device:
Instead of assigning a status of Archived, you can delete the device. However, all information specified for the device will also be deleted. If a deleted device is detected again, the application will provide only the information that has been received since the device was re-added to the devices table (the date and time of the first detection of the device is also updated).
