How to Configure the Microsoft Network Adapter Multiplexor protocol?
-->Applies to: Windows Server (Semi-Annual Channel), Windows Server 2016
Jan 11, 2017 You can't use the windows driver for teaming because doesn't contain multiplexer protocol. Proposed as answer by Cartman Shen Microsoft contingent staff Wednesday, January 11, 2017 3:38 AM Friday, December 30, 2016 7:53 AM. Mar 05, 2020 Should I Enable the Microsoft Network Adapter Multiplexor Protocol? As I mentioned before, the Protocol only works when teaming or combining multiple Network Adapters. If you try to enable this option by selecting the option manually while the other items in the list are enabled, you will see this error.
In this topic, we provide you with instructions to deploy Converged NIC in a Teamed NIC configuration with Switch Embedded Teaming (SET).
The Multiplexor protocol is used for multiple network adapters, not multiple PFs within the same card. (PF=Physical function). I think what you want is 'NIC Teaming' and you can use the LBFO utility to configure when not in Hyper-V. Oct 14, 2018 For example, if there are two physical network adapters in a team, the Microsoft Network Adapter Multiplexor protocol will be disabled for these two physical network adapters and checked in the teamed adapter. This driver is used for two scenarios in teaming. Both of these scenarios require at least two connected network adapters on a single PC. I reinstalled windows server couple of times and each time the drivers are not being picked up. My motherboard is ASRock Z97 Extreme 4. I tried installing the drivers from manufacturers website and it wont let me install the network adapter driver. When I try to install intel LAN driver v20. It says no intel adpater found. Please share your wisdom.
The example configuration in this topic describes two Hyper-V hosts, Hyper-V Host 1 and Hyper-V Host 2. Both hosts have two network adapters. On each host, one adapter is connected to the 192.168.1.x/24 subnet, and one adapter is connected to the 192.168.2.x/24 subnet.
Step 1. Test the connectivity between source and destination
Ensure that the physical NIC can connect to the destination host. This test demonstrates connectivity by using Layer 3 (L3) - or the IP layer - as well as the Layer 2 (L2) virtual local area networks (VLAN).

Use a separate subnet, (xxx.xxx.2.xxx vs xxx.xxx.1.xxx), to facilitate sending from this adapter to the destination. Otherwise, if you locate both pNICs on the same subnet, the Windows TCP/IP stack load balances among the interfaces and simple validation becomes more complicated.
Step 2. Ensure that source and destination can communicate
In this step, we use the Test-NetConnection Windows PowerShell command, but if you can use the ping command if you prefer.
Verify bi-directional communication.

If you disable the firewall, keep security in mind and ensure that your configuration meets your organization's security requirements.
Disable all firewall profiles.
After disabling the firewall profiles, test the connection again.

Step 3. Configure the VLAN IDs for NICs installed in your Hyper-V hosts
Many network configurations make use of VLANs, and if you are planning to use VLANs in your network, you must repeat the previous test with VLANs configured.
For this step, the NICs are in ACCESS mode. However, when you create a Hyper-V Virtual Switch (vSwitch) later in this guide, the VLAN properties are applied at the vSwitch port level.
Because a switch can host multiple VLANs, it is necessary for the Top of Rack (ToR) physical switch to have the port that the host is connected to configured in Trunk mode.
Note
Consult your ToR switch documentation for instructions on how to configure Trunk mode on the switch.
The following image shows two Hyper-V hosts with two network adapters each that have VLAN 101 and VLAN 102 configured in network adapter properties.
Tip
According to the Institute of Electrical and Electronics Engineers (IEEE) networking standards, the Quality of Service (QoS) properties in the physical NIC act on the 802.1p header that is embedded within the 802.1Q (VLAN) header when you configure the VLAN ID.
Configure the VLAN ID on the first NIC, Test-40G-1.

It might take several seconds for the device to restart and become available on the network.
Verify the connectivity for the first NIC, Test-40G-1.
If connectivity fails, inspect the switch VLAN configuration or destination participation in the same VLAN.
Results:
Parameter Value ComputerName 192.168.1.5 RemoteAddress 192.168.1.5 InterfaceAlias Test-40G-1 SourceAddress 192.168.1.5 PingSucceeded True PingReplyDetails (RTT) 0 ms Verify the connectivity for the first NIC, Test-40G-2.
If connectivity fails, inspect the switch VLAN configuration or destination participation in the same VLAN.
Results:
Parameter Value ComputerName 192.168.2.5 RemoteAddress 192.168.2.5 InterfaceAlias Test-40G-2 SourceAddress 192.168.2.3 PingSucceeded True PingReplyDetails (RTT) 0 ms Important
It's not uncommon for a Test-NetConnection or ping failure to occur immediately after you perform Restart-NetAdapter. So wait for the network adapter to fully initialize, and then try again.
If the VLAN 101 connections work, but the VLAN 102 connections don't, the problem might be that the switch needs to be configured to allow port traffic on the desired VLAN. You can check for this by temporarily setting the failing adapters to VLAN 101, and repeating the connectivity test.

Step 4. Configure Quality of Service (QoS)
Note
You must perform all of the following DCB and QoS configuration steps on all hosts that are intended to communicate with each other.
Install Data Center Bridging (DCB) on each of your Hyper-V hosts.
- Optional for network configurations that use iWarp.
- Required for network configurations that use RoCE (any version) for RDMA services.

Download the Test-RDMA PowerShell script to a test folder on your local drive, for example, C:TEST.
Run the Test-Rdma.ps1 PowerShell script to pass the ifIndex value to the script, along with the IP address of the first remote adapter on the same VLAN.
In this example, the script passes the ifIndex value of 14 on the remote network adapter IP address 192.168.1.5.
Results:
Note
If the RDMA traffic fails, for the RoCE case specifically, consult your ToR Switch configuration for proper PFC/ETS settings that should match the Host settings. Refer to the QoS section in this document for reference values.
Run the Test-Rdma.ps1 PowerShell script to pass the ifIndex value to the script, along with the IP address of the second remote adapter on the same VLAN.
In this example, the script passes the ifIndex value of 13 on the remote network adapter IP address 192.168.2.5.

Step 6. Create a Hyper-V vSwitch on your Hyper-V hosts
The following image shows Hyper-V Host 1 with a vSwitch.
Create a vSwitch in SET mode on Hyper-V host 1.

Results:
Step 7. Remove the Access VLAN setting
In this step, you remove the ACCESS VLAN setting from the physical NIC and to set the VLANID using the vSwitch.
You must remove the ACCESS VLAN setting to prevent both auto-tagging the egress traffic with the incorrect VLAN ID and from filtering ingress traffic which doesn't match the ACCESS VLAN ID.
Remove the setting.
Set the VLAN ID.
Results:
Test the network connection.
Results:
IMPORTANT If your results are not similar to the example results and ping fails with the message 'WARNING: Ping to 192.168.1.5 failed -- Status: DestinationHostUnreachable,' confirm that the “vEthernet (VMSTEST)” has the proper IP address.
If the IP address is not set, correct the issue.
Rename the Management NIC.

Step 8. Test Hyper-V vSwitch RDMA
The following image shows the current state of your Hyper-V hosts, including the vSwitch on Hyper-V Host 1.
Set the priority tagging on the Host vNIC to complement the previous VLAN settings.
Results:
Name : MGTIeeePriorityTag : On
Create two host vNICs for RDMA and connect them to the vSwitch VMSTEST.
View the Management NIC properties.

Step 9. Assign an IP address to the SMB Host vNICs vEthernet (SMB1) and vEthernet (SMB2)
The TEST-40G-1 and TEST-40G-2 physical adapters still have an ACCESS VLAN of 101 and 102 configured. Because of this, the adapters tag the traffic - and ping succeeds. Previously, you configured both pNIC VLAN IDs to zero, then set the VMSTEST vSwitch to VLAN 101. After that, you were still able to ping the remote VLAN 101 adapter by using the MGT vNIC, but there are currently no VLAN 102 members.
Remove the ACCESS VLAN setting from the physical NIC to prevent it from both auto-tagging the egress traffic with the incorrect VLAN ID and to prevent it from filtering ingress traffic that doesn't match the ACCESS VLAN ID.
Results:
Test the remote VLAN 102 adapter.
Results:
Add a new IP address for interface vEthernet (SMB2).
Results:
Test the connection again.
Place the RDMA Host vNICs on the pre-existing VLAN 102.
Results:
Inspect the mapping of SMB1 and SMB2 to the underlying physical NICs under the vSwitch SET Team.
The association of Host vNIC to Physical NICs is random and subject to rebalancing during creation and destruction. In this circumstance, you can use an indirect mechanism to check the current association. The MAC addresses of SMB1 and SMB2 are associated with the NIC Team member TEST-40G-2. This is not ideal because Test-40G-1 does not have an associated SMB Host vNIC, and will not allow for utilization of RDMA traffic over the link until an SMB Host vNIC is mapped to it.

View the VM network adapter properties.
Results:
View the network adapter team mapping.
The results should not return information because you have not yet performed mapping.
Map SMB1 and SMB2 to separate physical NIC team members, and to view the results of your actions.
Important
Ensure that you complete this step before proceeding, or your implementation fails.
Results:
Confirm the MAC associations created previously.
Results:
Test the connection from the remote system because both Host vNICs reside on the same subnet and have the same VLAN ID (102).

Results:
Set the name, switch name, and priority tags.
Results:

Results:
Enable the vEthernet network adapters.
Results:
Step 10. Validate the RDMA functionality
You want to validate the RDMA functionality from the remote system to the local system, which has a vSwitch, to both members of the vSwitch SET team.
Because both Host vNICs (SMB1 and SMB2) are assigned to VLAN 102, you can select the VLAN 102 adapter on the remote system.
In this example, the NIC Test-40G-2 does RDMA to SMB1 (192.168.2.111) and SMB2 (192.168.2.222).
