Automatically rediscovering your network and updating devices that use DHCP

Your network probably has devices that connect and disconnect to it rather frequently, such as laptops or other mobile devices. You can automatically discover these devices and add them to your group by scheduling a network discovery.

For devices in your device group that use DHCP, you may want to periodically rediscover them so that Observer Infrastructure has current address information. This can be done manually or automatically.

To automatically find changes and add devices to your group:

1.	In the Device Groups/Routes list, right-click a device group and choose Device Group Properties.

2.	Click the Poll tab.

3.	Enable autopolling.

Enable “Periodically Rediscover devices every __ minutes” and choose how frequently Observer Infrastructure should query your network for changes to existing devices (like DHCP addresses) and new devices that have come online.

Any changes to existing devices are automatically reflected in the device. Any new devices are added to the map, but are not connected to any other devices. You can manually add connecting lines if desirable.
