2.8.8 Managing the network control list
By using the network control list, you can control network access at the device level. You can also specify a time period during which a device is permitted to access the network. Newly discovered devices are automatically registered in the network control list, but an administrator can register devices manually when needed.
To control network access at the device level, add devices to the network control list.
You can change the network access of a specific device by editing its entry in the network control list.
Devices that were manually added to the network control list can be removed from the list.

By combining network monitor settings with the contents of the network control list, you can use a whitelist or blacklist approach to controlling network access.

When the Enable all automatic updates check box is selected in the Automatic Updates on Network Filter List dialog box: If you delete a device whose network access is set to Permit, the device is also deleted from the network control list. This prevents the information for the device from being misused in the future. Conversely, if you delete a device whose network access is set to Not Permit, the device remains in the network control list to ensure the Not Permit setting is maintained if the device is changed.
-
When the Enable all automatic updates check box is not selected in the Automatic Updates on Network Filter List dialog box (that is, automatic updating for only additions is enabled): If you delete a device, the entry for the device remains in the network control list regardless of whether Permit or Not Permit is set.

- Important note
-
When you use a MAC address to enter a device in the network control list, the MAC address is correlated with any device information JP1/IT Desktop management collects for the device. This means that the host name or other information will be displayed instead of the MAC address. After this occurs, you can no longer delete the device from the network control list window. To delete such a device, use the Settings module.
