Last week, my colleague Claudia and I have ported a HP ProVision configuration to HP Comware. Unexpectedly, it wasn’t routing or VLANs or OSPF that caused headaches, it was a Wake-on-LAN (WoL). Depending on the used tool, the magic packet (which wakes up the computer) is a broadcast (255.255.255.255) or a subnet-directed broadcast (e.g. 192.168.200.255). So it was important to know what tool the customer used.
This is how HP ProVision implements subnet-directed broadcasts:
ip address 192.168.200.254 255.255.255.0
ip forward-protocol udp 10.0.0.255 9
ip address 10.0.0.254 255.255.255.0
