Locally Administered Address

The Locally Administered Address overrides the initial MAC address with a user- assigned MAC address. To enter a new network address, type a 12-digit hexadecimal number in this box.

To change this setting in Intel® PROSet:

This setting is found on the Advanced tab of the device’s Device Manager property sheet or in the Adapter Settings panel in Intel® PROSet Adapter Configuration Utility (Intel® PROSet ACU).

To change this setting in Windows PowerShell*, use the Set-IntelNetAdapterSetting cmdlet. For example:

Set-IntelNetAdapterSetting -Name "<adapter_name>" -DisplayName "Locally
Administered Address" -DisplayValue "<desired address>"

Possible values for this setting are:

  • 0000 0000 0001 - FFFF FFFF FFFD

Note:

Exceptions:

  • Do not use a multicast address (Least Significant Bit of the high byte = 1). For example, in the address 0Y123456789A, Y cannot be an odd number. (Y must be 0, 2, 4, 6, 8, A, C, or E.)

  • Do not use all zeros or all Fs.

  • If you do not enter an address, the address is the original network address of the adapter. For example:

    Multicast: 0123 4567 8999 Broadcast: FFFF FFFF FFFF
    Unicast (legal): 0070 4567 8999
    
Note:

In a team, Intel PROSet uses either of the following:

  • The primary adapter’s permanent MAC address if the team does not have an LAA configured

  • The team’s LAA if the team has an LAA configured

Intel PROSet does not use an adapter’s LAA if the adapter is the primary adapter in a team and the team has an LAA.
