![]() Changes made with SET will remain only for the duration of the current CMD session. set - Display, set, or remove CMD environment variables.parameters - A command line argument (or parameter) is any value passed into a batch script.getmac - Display the Media Access Control (MAC) address and list of network protocols associated with each address for all network cards in each computer, either locally or across a network.for /f - Loop command against the results of another command.find - Search for a text string in a file & display all the lines where it is found.An A-Z Index of the Windows CMD command line - An excellent reference for all things Windows cmd line related.Note in a batch file every % must be replaced by %%. %~a is used to remove the quotes from the string, leaving: F0-BF-97-62-95-5Dįinally variable MAC is set to F0-BF-97-62-95-5D: set MAC=%~a Returns the 3rd token (value) from the comma delimited string as follows: "F0-BF-97-62-95-5D" The string is passed to the for command (by using the ` (backquote) character together with usebackq: for /f "usebackq tokens=3 delims=," %a in (`string`) do Now we use the for command to extract just the MAC address from the above string. The third (comma delimited) value is the MAC address. "Connection Name","Network Adapter","Physical Address","Transport Name" Output: (using getmac /fo csv /v and wifi hotspot OFF) So, how can I collect only the address corresponding to Ethernet via command prompt? Also there are some virtual MAC addresses-like Microsoft Virtual Wi-Fi hotspot NIC-which shows only when wifi hotspot is on. Type in the MAC address of your host laptop.I use ipconfig /all or getmac /v to get all NIC physical addresses.īut the problem is, generally a computer has more than one NIC card. Go to Configure and click the Advanced tab and then Network address. Locate the Network Interface Controller (NIC) for your Dock (typically Realtek GBE Ethernet) and right-click it and select Properties from the menu that appears. If the MAC Pass-Through is already enabled in the BIOS, but this is not reflected inside the operating system? You must update the BIOS and the Dock Network driver (Realtek Gigabit Ethernet (GBE).) Install the latest update revisions available from the Dell Support site for your laptop. Save your changes and restart the laptop. Go to System Configuration and locate: MAC address Pass-Through: System Unique MAC Address Steps to enable MAC Pass-Through in the BIOS: Use this method to obtain the MAC Address of your local computer as well as query remotely by computer name or IP Address. ![]() You can find it under System Information. The Physical Address is listed, that is the MAC Address of your network card. Start the laptop and tap rapidly on the F2 or F12 key at the Dell Splash screen to enter the BIOS. Without the USB-C Dock or network adapter, attached: With the USB-C Dock or network adapter, attached:įrom a command-line prompt run either of the following commands: Steps to determine the passthrough MAC address This ensures that the docked Static IP laptops are manageable on the network. (This is due to the dock running the default Dynamic Host Configuration Protocol (DHCP) IP Address configuration.)Īssigning and configuring a Static IP address on the dock ensures that the MAC Address pass-through functions properly. It prevents your IT from managing the laptop on the network when the laptop is on a docking station. However, when a docked laptop is configured with a Static Internet Protocol (IP) Address, the dock can block any MAC Address pass-through communication. Unique hardware MAC Addresses are used to identify and manage individual assets on a network. This ensures that these assets comply with the availability and discoverability requirements of the managing IT group. Laptops that are joined to a managed network often rely on Static IP Addresses. It overrides the dock or dongle MAC address every time that it connects to the network. It is entered in the Basic Input Output System (BIOS). ![]() It uses a MAC address that is unique to the laptop. This is a feature that Dell named MAC Address Override or MAC Address Pass-Through. Pass-Through Media Access Control (MAC) address is also known as the Virtual MAC address, or the Auxiliary MAC address. (For example: Adding it to the approved list.) However, this article assumes that you have a valid reason. ![]() Note: There are many different reasons why you must know this information.
