Setting the Locally Administered Address for a Team or VLAN

The Locally Administered Address (LAA), a persistent MAC address, must be set for each Ethernet team and VLAN to ensure that the MAC address will not change when you reboot the system or temporarily remove an I/O module.

If you initially create teams with the LBFO teaming script, it automatically sets the LAA for each team; however, you may need to manually set the LAA if you:

• Remove or replace an adapter in an existing team.

• Add more than one VLAN interface to a team.

• Initially create teams with the NIC teaming utility instead of the LBFO teaming script.

Typically, a team's LAA is the same as the MAC address of the primary adapter in the team. If you replace the primary adapter, the team continues to use the LAA that matches the MAC address of the original primary adapter unless you manually update the LAA to match the MAC address of the new primary adapter. If you have configured multiple VLAN interfaces for the team, you must also update the LAA for each VLAN interface to the new primary MAC address.

To set the LAA for a team or VLAN

1. Use the LBFO teaming script list operation to display the adapter name and MAC address with each Ethernet PCIe adapter and team as shown in II. Displaying the Current Configuration of Ethernet PCIe Adapters.

2. In the NIC Teaming utility, under ADAPTERS AND INTERFACES, click the Team Interfaces tab.

3. On the Team Interfaces tab, expand the target team, click the team interface (or the first interface if more than one is present), and select Properties.

4. Under General information, make note of the Description and Permanent address of the team interface. The description should be similar to Microsoft Network Adapter Multiplexor Driver #n and the permanent address should match the MAC address of one of the adapters currently in the team, which you collected in step 1.

   Note: Although the NIC teaming utility displays the Permanent address for the team, the address is not persistent until you complete this procedure, which preserves the team's MAC address in the system registry.

5. Open Device Manager and expand Network adapters.

6. Locate the team interface, which is listed in Device Manager by the Description you collected in step 4. Because each team has a similar description, ensure that you select the correct entry.

7. Right-click the team interface and select Properties.

8. In the Properties dialog box, click the Advanced tab.

9. Locate and click the MAC Address property. Under Value, carefully type the MAC address for the team (or Permanent address), which you confirmed in step 4.

   When typing the address, do not include any dashes (-), colons (:), or spaces. For example, if the address is A0-36-9F-5A-BA-C0, type A0369F5ABAC0.

10. Click OK to set the address and close the dialog box.

11. If the team has multiple interfaces (including VLANs), repeat steps 3-10.

After setting the LAA, confirm the setting by using one of the following procedures.

To confirm the LAA is set for a team or VLANs with Windows PowerShell

You can verify that the LAA has been set by executing a command similar to the following in Windows PowerShell, where team-name is the name of the default team interface or VLAN interface:

PS> (Get-netadapterAdvancedProperty -Name team-name* -RegistryKeyWord NetworkAddress).DisplayValue

Inserting the wildcard (*) with the team-name* displays information for all interfaces associated with the team (including VLANs, if present), as follows:

> (Get-NetAdapterAdvancedProperty -Name Embedded-* -RegistryKeyword NetworkAddress)
Name          DisplayName   DisplayValue   RegistryKeyword  RegistryValue
----          -----------   ------------   ---------------  -------------
EMBEDDED-2    MAC Address   0004FCF82F12   NetworkAddress   {0004FCF82F12}
EMBEDDED-1    MAC Address   0004FCF82F13   NetworkAddress   {0004FCF82F13}

The preceding example shows that the LAA has been set for both embedded teams and that no further action is needed.
