I am having problems waking up systems using wake on lan. I am running a star topology, when the server is on the same hub as the system thats needs to be woken up it works fine. When the server is on another hub it wont work. The hubs are all connected into a backbone switch.

I am not sure what series switches you are using. However, if you enable portfast on the ports with computers or servers directly connected it will most likely solve the problem. With portfast disabled, items like DHCP etc. time out during the listen, learning, blocking, forwarding state.

Actually in this network I am not running Cisco switches. What I don't understand is that wake-on-lan works based on the hardware address. There are two ways to wake the machine, 1.) to send a broadcast to the segment where the machine is located 2.) to send the frames directly to the machine using the hardware address of the noc card on the machine. I have tried both with no luck.
