when I found out that ether-wake only did raw ether packets, I notoced there's also a wol in the distro,  that broadcasts wake up packets using udp, that I can redirect on cisco equipment.  It's working now. thanks, Ron On 5/18/20 9:45 AM, Simon Matter via CentOS wrote: Actually you are

yeah I am wondering if that isn't the easiest route to go though if there already is one. I am waiting for an answer from Cisco. Cisco switches and routers can forward wol packets sent over udp. But etherwake doesn't do that apparently. So if I want to wake up machines from a central

Some switch hardware can generate the packets directly, negating the need for a box on every VLAN. Meraki hardware can do it, but you have to go through the dashboard so automating it isn't currently possible. Here is some documentation on forwarding WoL on catalyst 3750 switches from Cisco:

Ok,  I get that, found it before;  "typically sent as a UDP datagram to port 0, 7 or 9, or directly over Ethernet as EtherType 0x0842" The keyword being 'typically',   but what is it that ether-wake actually uses/does?  (I need to forward a WOL packet to a different vlan on some Cisco

The WoL magic packet is only scanned for the string above, and not actually parsed by a full protocol stack, it could be sent as any network- and transport-layer protocol, although it is typically sent as a UDP datagram
