This address is the sublayer of Data-link, can actively participate in the network connections of a device. By implementing this method, there is no possibility of having two same MAC addresses because the number of combinations present in forming a 12-digit address is usually in hundreds of trillions. This format uses base-16 to identify individual numbers of the address. In technical terms, a MAC address is defined as a long address consisting of 48 bits, and it follows a hexadecimal format. This article will be different aspects of MAC addresses and see how we can change it across different platforms. If it is easy to identify and establish contact, then communication between two systems becomes more stable and reliable in any situation.
These addresses or identifiers are unique because they can be recognized in a network that combines many devices. The hardware component that carries this address is stored in the network card. The Media Access Control address works as a data link layer. This address is also responsible for establishing communication between two desktop-based computers. When the system components are being manufactured, the company assigns a unique number to the device to be identified at any point in time. Some also called this the hardware address of a system. Still, another component called MAC address is associated with physical routers and network adapters. Why should you change your MAC address?Īn IP address is not the only thing important when it comes to the network interface and communication. Thus I created the procedure detailed above, where essentially I get around the vSphere GUI.List of content you will read in this article: I just need to be able to retain it when replacing the virtual NIC, such as in the example of going from a "Flexible" NIC to a VMXNET2 NIC. My problem is not the fact that you can't assign just any old MAC - I'm quite alright using the VMware assigned MAC. Same thing there - you can change the MAC address with the ifconfig command but when I tried it, the app wouldn't acknowledge it. In addition to that 2 of the apps I'm working with are Linux based. I've tried it, and one of the apps was smart enough to "sniff out" the MAC assigned by VMware. Sorry, guys, changing the MAC from inside the guest OS does not work for all apps.
However I do plan on putting that in place later this year, and that's where I'm not sure it my little procedure will come up to surprise me at that point. I am currently running a "vanilla" network setup - no distributed vSwitches. The question is: Will this cause any problems down the road? So far it has worked for me just fine on two test servers. vmx file and replace the automatically assigned MAC address with the old MAC address
So, here's the procedure I'm using to keep the MAC address:Ĥ) Edit the. Since I didn't plan ahead far enough to manually put in those MAC addresses, now I have no choice but to find some way to keep them until the vendors can regen the licensences. And yes, now I have to change virtual NICs on several VMs from either Flexible or E1000 to VMXNET2.Ĭurrently running vSphere 4.1, ESX build 320092 across the board.

I have several apps that generate their license based on a server's MAC. I'm pretty sure it wasn't mentioned in the class, either. Somehow I think that should have been written in big, bold letters before I started virtualizing a couple of years ago.

I think we are all familiar with the manual MAC address issue - some software depends on the MAC for licensing, and in VMware you need to stick to a certain range of Ethernet addresses if you want to be able to manually put in your own MAC address.
