Retrieving MAC Addresses

To send a Wake-on-LAN package to a remote Machine, Remote Shutdown firstly should be introduced to its MAC address. Although it is possible to provide a MAC address manually while editing Machine's properties, the program provides you with a techniques of retrieving the MAC address automatically.

Info

In case if the Wake-on-LAN operation is initiated for Machines that has no MAC address retrieved, Remote Shutdown will try to retrieve it automatically for each Machine before sending a magic packet. Only the Neighbor Discovery, IPv6 EUI-64 and DHCP methods for retrieving MAC addresses are used when getting the MAC address in a scope of the Wake-on-LAN operation, as the Machine should be turned on to be able to use the NetBIOS, WinAPI and WMI methods.

With Remote Shutdown, you can either retrieve MAC addresses for remote Machines immediately, or create a preconfigured task to run MAC addresses scan in the future, or schedule such tasks to be executed once or on a regular basis – this section will show you how to reach all these goals.

Performing MAC Address Scan

The MAC addresses are retrieved automatically for the Machines being added during the network enumeration process. If there is no access to DHCP server or the Machines retrieved are turned off, the MAC address is not retrieved, but you can retrieve it manually any time you want.

Retrieve MAC

Retrieve MAC

The Retrieve MAC Address button from the Administration Ribbon group on the Remote Actions page should be used to retrieve MAC addresses for the remote Machines.

To retrieve the MAC addresses that have not been retrieved or update the already retrieved addresses, use the Retrieve MAC Address button from the Administration Ribbon group on the Remote Actions page. If the Network or the All Machines view is active, the selected Machines and Collections are automatically added to the operation's Machine Queue. This action is also available from the Administration group from the Home Ribbon page and the corresponding group in pop-up menus and on toolbars of the Network and All Machines views. The wizard will appear on the screen and guide you through the operation configuration process Pic 1.

Configuring a MAC address scan operation

Pic 1. Configuring a MAC address scan operation

When configuring a MAC address scan operation you can override a set of methods used for fetching MAC addresses, if required, and define a set of Machines to be operated. To learn more about the MAC address scan methods, refer to the MAC Address Retrieving Methods section. For the information on configuring a scope of Machines, refer to the Defining Machines to Operate section of this document. Once you are done with configuring the scan, press Finish to proceed. The MAC address scan operation will start automatically, and as soon as it is completed, you will be able to see the execution results in the Execution Results view.

Creating a new Retrieve MAC Address Task

If you do not want to scan Machines for their MAC addresses right now, with Remote Shutdown you can create a preconfigured task to perform scan in future, any time you want. While creating a new task, you can override a set of methods used for fetching MAC addresses, if required. To create a new Retrieve MAC Address task for further execution, you should choose the New Task > Retrieve MAC Address item from the Tasks area pop-up menu. Alternatively you can use the New Task button from the Tasks area toolbar or the Regular Task button from the New Ribbon group on the Management contextual page from the Tasks and Schedule Tools category. The New Task wizard will appear on the screen and guide you through the process of creating a new task. Once you are done with configuring the task, press Create to create it. The newly created task will be added to the Tasks area. A created task can be executed manually any time using the Run menu item from the Tasks area or scheduled for automatic execution. Remote Shutdown will store the results for all runs of this task, and you can review all of them in the Execution Results view.

Performing a MAC address scan on schedule

As it has already been mentioned, with Remote Shutdown you can run a preconfigured Retrieve MAC Address task any time you want. However, manual task execution may not be convenient for you since in such a case you would always have to remember when you should perform this or that scan. The scheduling engine integrated into Remote Shutdown can always keep this in mind for you, so that you can concentrate on your other everyday tasks.

To schedule a new Retrieve MAC Address task, you should choose the Scheduled Task > Retrieve MAC Address item from the New Ribbon group on the Home page. This option is also available in the Scheduling area pop-up menu and on the toolbar. Alternatively, you can select the Machines you want to scan for their MAC addresses in the Network or the All Machines view and choose the New > Scheduled Retrieve MAC Address Task menu item from the pop-up menu to initialize the Machine Queue with the selected Machines.

When scheduling a task, you can override the MAC address scan options, if required, and specify a set of Machines to scan for MAC addresses. Once you are done with configuring the task, press Schedule for the task to be put on schedule. The scheduled task will be added to the Scheduling area. A scheduled task is executed automatically when its start time comes. Remote Shutdown stores the results for all runs of such a task, and you can review all of them in the Execution Results view.
