Wake on LAN

SD-WAN Edge supports subnet directed broadcasts on virtual interfaces, which are used primarily to enable Wake on LAN-type packets.

Wake on LAN (WOL) is a combination of hardware and software technologies to wake up sleeping computers. It allows the administrator to remotely power up all sleeping machines so that they can receive updates. WOL is based on the principle that when the host shuts down, the NIC still receives power, and keeps listening on the network for the required packet to arrive.

To allow WOL packets to traverse your SD-WAN Network, the SD-WAN devices must be configured to allow directed broadcasts.
