WoL Relay
61.1 WoL Relay Overview
Wake On LAN is a feature to remotely turn on a device on the LAN network. A device is turned on by
receiving a magic packet. To use this feature the remote hardware (for example the network adapter
on a computer) must support Wake On LAN using the “Magic Packet” method.
A magic packet is a UDP broadcast packet. The device that you want to turn on is off, so it cannot
respond to a TCP packet. Therefore, It has to be a UDP broadcast packet to turn on a device.
Broadcast packets are generally not routed. A magic packet cannot be routed. This prevents DDoS
attacks, but also prohibits you from sending magic packets to other devices in different subnets. The
Switch’s Wake On LAN relay feature allows you to send magic packets to devices across different
subnets.
