Windows server 2016, 2 NIC ports, teamed with Microsoft Network Adapter Multiplexor Driver, no VMs, no VPNs, no load balancer. After rebooting, the MAC address keeps changing (based on IPCONFIG /all). Application software is based on MAC, so the application keeps failing after reboot.

Gets MAC addresses from the allow list or the deny list on the DHCP server service.

Syntax

Description

The Get-DhcpServerv4Filter cmdlet gets the list of all MAC addresses from the allow list or the deny list on the Dynamic Host Configuration Protocol (DHCP) server service.

If the List parameter is not specified, both allow and deny filters are returned.

Examples

Example 1: Get all MAC address for a computer

This example gets all of the MAC addresses in the allowed and denied lists configured on the DHCP server service on the computer named dhcpserver.contoso.com.

Parameters

Runs the cmdlet as a background job.Use this parameter to run commands that take a long time to complete.The cmdlet immediately returns an object that represents the job and then displays the command prompt.You can continue to work in the session while the job completes.To manage the job, use the *-Job cmdlets.To get the job results, use the Receive-Job cmdlet.For more information about Windows PowerShell速 background jobs, see about_Jobs.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False

Runs the cmdlet in a remote session or on a remote computer.Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet.The default is the current session on the local computer.

Type:CimSession[]
Aliases:Session
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False

Specifies the DNS name, or IPv4 or IPv6 address, of the target computer that runs the DHCP server service.

Type:String
Aliases:Cn
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False

Specifies the list from which one or more MAC addresses are to be retrieved.The acceptable values for this parameter are: Allow or Deny.

Type:String
Accepted values:Allow, Deny
Position:1
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False

Specifies the maximum number of concurrent operations that can be established to run the cmdlet.If this parameter is omitted or a value of 0 is entered, then Windows PowerShell速 calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer.The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Type:Int32

Default value:None
Accept pipeline input:False
Accept wildcard characters:False

Outputs

Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/DHCP/DhcpServerv4Filter[]

This article provides information about System Center - Virtual Machine Manager (VMM) default MAC addresses, and describes how to create and manage a custom MAC address pool. Microsoft visio mac reddit 2017.

VMM uses static MAC address pools to automatically generate and assign MAC address to VMs. This article describes default MAC address pools in the VMM fabric and explains how to create custom pools.

Default MAC address pool settings:

MAC pool nameEnvironmentDefault range
Default MAC address poolHyper-V00:1D:D8:B7:1C:00 – 00:1D:D8:F4:1F:FF
Default VMware MAC address poolESX/ESXi00:50:56:00:00:00 – 00:50:56:3F:FF:FF

Before you start

Before you create a custom MAC pool note that:

  • If you want to divide one of the default pools into smaller custom pools, you must first delete the default MAC address pool or the default VMware MAC address pool. You must delete the default pool to avoid duplicate MAC address assignments.
  • The first three octets of the beginning and ending MAC address must be the same.
  • You must enter a valid hexadecimal values between 00 and FF.
  • The ranges that you specify cannot overlap.
  • The address range must not have the multi-cast bit set to 1. For example, you cannot use addresses that start with X1, X3, X5, X7, X9, XB, XD, or XF, where X is any value.
  • To avoid conflicts with addresses reserved by Microsoft, VMware, and Citrix, do not use the following prefixes:
    • Reserved for Microsoft: 00:03:FF; 00:0D:3A; 00:12:5A; 00:15:5D; 00:17:FA; 00:50:F2; 00:1D:D8 (except for the 00:1D:D8:B7:1C:00 – 00:1D:D8:F4:1F:FF range that is reserved for VMM)
    • Reserved for VMware: 00:05:69; 00:0C:29; 00:1C:14; 00:50:56 (except for the 00:50:56:00:00:00 – 00:50:56:3F:FF:FF range that is the reserved as the default VMware static range)

Create a custom pool

  1. Click Fabric > Networking > MAC Address Pools > Home > Show > Fabric Resources > Create > Create MAC Pool.
  2. In Create MAC Address Pool Wizard > Name and Host Group specify a name and description. In Host Group select the host groups that should use the pool.
  3. In MAC Address Range specify the start and end addresses.
  4. In Summary review the settings and click Finish. When the job shows as Completed verify pool in MAC Pools.

Release IP addresses

In some circumstances you might want to remove addresses from the MAC pool. For example if a host that was assigned an IP address during bare metal deployment is removed from VMM management, or if a VM goes into a missing state because it was removed outside VMM.

  1. Click Fabric > Networking > MAC Address Pools > Home > Show > Fabric Resources.
  2. In MAC Pools click the pool you want to modify > Properties.
  3. In Inactive addresses select the addresses you want to release.
