Wake-on-LAN is an industry standard protocol that, given that the device has access to a power source, allows for compatible devices to be turned on or awakened remotely. It typically only works for laptops that are connected to the main supply. The Wake-on-LAN functionality can be especially useful when maintenance tasks, such as backups or installation of software upgrades need to be performed on a device after business hours.
If the device is in sleep mode or turned off but has access to a power source, it will continue to scan data coming in from the network. If configured, it will be able to look for a special data sequence called Magic Packet to wake up the device.
NOTE Magic Packets are usually sent over the entirety of a network and contain the subnet information, network broadcast address and MAC address of the target computer’s network card, whether Ethernet or wireless.
In Datto RMM, Wake-on-LAN requires an online Agent in the same site and subnet as the device you wish to wake up. The remote device also needs to be properly configured as detailed below.
Requirements for Wake-on-LAN in Datto RMM
In Datto RMM an Agent can send a Magic Packet to wake up a remote device if:
- The Agent is in the same site and subnet as the device you would like to wake up
- UDP Ports 7 and 9 are enabled on the remote device
- The remote device's network adapter is enabled to allow a Magic Packet to wake the device
- Log into the Agent Browser. Refer to Log into the Agent Browser.
- Connect to a device in the same site and subnet as the device you wish to wake. Refer to Connect to a device.
- Click Tools > Wake Up or click the Wake up remote devices icon .
- The Wake Up tab will open on the right of the window and will show a list of all the offline devices that are in the same site and subnet as your connected device.
- Select the device(s) that you wish to wake up and click Wake Up.
- This will send a Magic Packet to the remote device(s) so that you can perform further actions on them. To learn about the remote tools that you have at your disposal, refer to Agent Browser tools.
Datto RMM supports Wake-on-LAN requests in Patch Management policies to wake the targeted devices before the policy is due to start. You must, however, have a Network Node device in the same site as your targeted devices to use this feature. (Local Caches can also be nominated as Network Nodes.)
For further information, refer to Nominate a device as a Network Node, and the POWER section in Create a Patch Management policy.
