Description

Use this cmdlet to view duplicate hardware identifiers by network MAC address. Configuration Manager ignores these MAC addresses for PXE boot and client registration. For more information, see Manage duplicate hardware identifiers.

Note

Run Configuration Manager cmdlets from the Configuration Manager site drive, for example PS XYZ:\>. For more information, see getting started.

Examples

Example 1: View all MAC addresses

This example displays all duplicate addresses from the site.

Get-CMDuplicateHardwareIdMacAddress | Select-Object MACAddress

Example 2: Test for a specific MAC address

The following example script checks if a specific address is found, and then writes a message based on the result.

$mac = "01:23:45:67:89:AB"

if ( Get-CMDuplicateHardwareIdMacAddress -Id $mac ) {
  Write-Host $mac "exists in the site"
} else {
  Write-Host $mac "doesn't exist!"
}
