Manual:Tools/Wake on lan
This tool is introduced in RouterOS since v3.23 and can send the Wake on LAN MagicPacket to any MAC address of your choosing. If the target device supports WOL, it should wake from sleep. Secure WOL is not supported.
[admin@MikroTik] > tool wol mac=FF:FF:FF:FF:FF
The WOL tool will send a UDP MagicPacket to the Broadcast address with the MAC address embedded in it.
By default, the magic packet will be sent as an IP broadcast out the default gateway interface, but if you want, you can tell the command to use a specific interface:
[admin@MikroTik] > tool wol interface=ether1 mac=FF:FF:FF:FF:FF:FF
