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.

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!"
}
