Use this article to learn about and set up uplink port profiles and virtual network adapter port profiles in the System Center Virtual Machine Manager (VMM) networking fabric.
It directs packets to MAC addresses. It handles VLAN tagging. It can even perform some Quality of Service (QoS) tasks. It’s also responsible for isolating network traffic to the virtual adapter that is supposed to be receiving it. When visualized, the Hyper-V network switch should be thought of in the same way as a standard switch. Aug 24, 2018 Create a VM and connect to a tenant virtual network or VLAN.; 4 minutes to read; In this article. Applies to: Windows Server (Semi-Annual Channel), Windows Server 2016. In this topic, you create a tenant VM and connect it to either a virtual network that you created with Hyper-V Network Virtualization or to a virtual Local Area.
Define uplink port profiles
Some guidelines for creating uplink port profiles:
![]() Create an uplink port profile
After you create an uplink port profile, the next step is to add it to a logical switch, which places it in a list of profiles that are available through that logical switch. When you apply the logical switch to a network adapter in a host, the uplink port profile is available in the list of profiles, but it is not applied to that network adapter until you select it from the list. This helps you to create consistency in the configurations of network adapters across multiple hosts, but also enables you to configure each network adapter according to your specific requirements.
Create a virtual network adapter port profile
After creating a port profile you can create a port classification.

Everyone knows the physical address (MAC address) of a network adapter must be unique, this condition is also true for virtual network adapters, if two or more virtual machines have the same MAC address, you are going to see Event ID 28, Source: VMSMP often appears in event view of the Hyper-V host. This is a real problem because one of the machines lose network connectivity affecting services.
Microsoft has ownership of the MAC addresses that begin by 00-15-5D. This address scope is reserved for Hyper-V. If you run the command IPCONFIG /ALL in a virtual machine and the MAC address starts with 00-15-5D know that this virtual machine is running on Hyper-V. Did you know that? For you to see which address scope Mac Address, open Hyper-V, right click the server name and select Virtual Switch Manager, then select MAC Address Range in the category Global Network Manager. I did this on my server and look down the start and end addresses.
There are a range of initial and final that known as minimum and maximum respectively address. Note that both the minimum and maximum address 00-15-5D begin with and the last address begins with 00 and ends with FF. Let's convert the address 00 and FF hex to decimal.

00 hexadecimal = 00 decimal
FF hexadecimal = 255 decimal Shazam for mac free download.
That means we have 254 available MAC addresses on Hyper-V, the first virtual machine created will have the MAC address 00-15-5D-00-03-01, the second one 00-15-5D-00-03-02 and so on until you reach the 00-15-5D-00-03-254 address. But as the addresses 00-03 were created? If you run the command ipconfig on the host Hyper-V you will have the answer. The third and the fourth octet of the IP address 172.16.0.3 were converted from decimal to hexadecimal
00 decimal = 00 hexadecimal
03 decimal = 03 hexadecimal
Gilson you're saying that the range of MAC address of Hyper-V physical server is created based on the IP address of the server? Yes, that's right, it uses the third and fourth IP address. This information is stored in the following registry key
HKLMSOFTWAREMicrosoftWindows NTCurrentCurrentVersionVirtualization
When you change the IP of the server and restarts the service of Hyper-V the range of MAC address does not change. Have you noticed that if another Hyper-V server has even temporarily the 172.16.0.3 IP address, it will have the same range of MAC address and the virtual machines have the same MAC address that a conflict will occur? Carefully before installing the Hyper-V in Windows make sure that the IP address used was never used on another Hyper-V server before, because there is a possibility of generating a conflict problem in the environment.
If you have two or more Hyper-V servers with the same range of MAC address, you have a problem, you must remove the two registry keys on one of the Hyper-V servers, remove the MaximumMacAddress and MinimumMacAddress keys and restart the service Hyper-V (no need to restart the server), In my lab I changed the address of the Hyper-V 172.16.0.3 to 172.16.0.4. After that, restart the service below:
Observe that MAC address range on Hyper-V was changed from 00-03 to 00-04
https://newho614.weebly.com/java-70-for-mac.html. And the virtual machines that already had the old MAC address 00-03 with conflict? they will be dynamically changed to 00-04? The answer is no, only new virtual machines created. To solve the existing MAC addresses on virtual machines 00-03 to 00-04, you need to remove the virtual network and add a new one.
After all this, take a look at the new MAC virtual machine and make sure that the address was changed to the 00-04 range, making these changes the IP address is lost, you need to configure it again.
For finished this post, don’t forget that System Center Virtual Machine Manager 2008/2012 takes a different approach when managing virtual machines and MAC addresses by using static MAC addresses from a defined pool. This pool is used across all hosts. By default the pool is in the range of 00-1D-D8-B7-1C-00 to 00-1D-D8-F4-1F-FF for 3,998,719 available MAC addresses Google earth for macbook air.
