Phenomenon:
Wake-on-lan does not work. When capture a traffic package, we will find the WOL magic packet was sent to different IP address instead of the real IP address of the client.
Root Cause:
If customer used to use multiple NIC cards, these multiple NIC cards information will be stored in the Inventory information. Wake-on-lan will send the magic packets to the very first NIC card IP address among the NIC cards list. So if that first NIC card has been decommissioned and still remains in the inventory information, the WOL magic packet will still be sent to it and causing the target device cannot recevie the WOL magic packet and then cannot be booted up.
We can check this out by going into the "Inventory","Network","TCPIP" and see if there are multiple NIC card information stored there and see if the first one has been decomissioned already (which is not currently being used by the client).
Resolution:
We will need to refresh the NIC card information by delete the entry of the client from the console and then re-run the inventory scan from the client side to refresh the inventory data.
