WakeOnLAN Parameter (Send-UDP Cmdlet)
Specifies the MAC address of the host.
Send-UDP -WakeOnLAN string
A "Wake-On-LAN" packet is sent to Server (which may also be a broadcast address). This has the effect of powering on the machine (if such functionality is supported by the network card on the remote machine).
The physical address of the remote host must be supplied in the WakeOnLAN parameter.
