What is Switch Embedded Teaming?
SET is basically a new and better version of NIC teams. The advantage of using a SET is that it provides better data transfer performance as the NICs to no have to send the data they send and receive via the CPU of the server, instead the data accesses the servers memory directly and passes straight through to the other NIC. These NICs can be made into Hyper-V switches to be used with virtual machines.
To enable Switch embedded teaming you need to have Remote Direct Memory Access enabled network cards. To see if you have RDMA enabled NICs run this cmdlet in PowerShell.
If you have RDMA enabled NICs you can create a Hyper-V switch with them with this command:
New-VMSwitch -Name SETvSwitch -NetAdapterName "NIC1","NIC2" -EnableEmbeddedTeaming $True
Once complete, you'll be able to select this new vSwitch as an adapter in Hyper-V. This will provide failover and load balencing at a higher performance than NIC Teaming.

1. Identify the Interface Index of the NIC you want to configure.
2. Set the IP address on the desired interface
New-NetIPAddress -InterfaceIndex 4 -IPAddress 10.0.0.120 –PrefixLength 24 -DefaultGateway 10.0.0.245
3. Finally, set the DNS addresses
Set-DnsClientServerAddress -InterfaceIndex 4 -ServerAddresses ("10.0.0.115","22.214.171.124")
How do we know this worked?

This guide will demonstrate how to migrate a role from one server to another; for this example we will migrate DHCP but this method can be amended to suit other roles. You should always follow Microsoft's guides and checklists when migrating roles.On source machine
Create a shared folder on the source machine called "Mig"On destination machine
Next if not already, intsall Windows Server Migration ToolsImport-Module ServerManager
smigdeploy.exe /package /architecture amd64 /os WS08 /path \\sourceserver\MigOn source machine
cd c:\Mig\<folder-name of your deployment>
Make sure the role being migrated is Installed on the destination server.
Make a note of the source NIC MAC address = getmac
Stop Service on Destinartion serverStop-Serve DHCP
Check with that it stopped with:Get-Service DHCP
Export-SmigServerSetting -FeatureID DHCP -Group -IPConfig -path C:\StorageMig -verbose
Prompted with a password.
Remove DHCP from ADnetsh DHCP delete server.domain.local 10.10.10.10On Destination server
We must import the snapin before we can use the Import-SmigServerSetting cmdlet.Add-PSSnapin Microsoft.windows.servermanager.migration
Import-Smigserversetting -FeatureID DHCP -IPConfig ALL -SourcePhysicalAddress <M-A-C-A-D-D-R-E-S-S> -TargetPhysicalAddress <M-A-C-A-D-D-R-E-S-S> -Path \\sourceserver\c$\StorageMig -VerboseStart-Service DHCP

etworks with VOIP might require SIP ALG (Session Initiation Protocol (SIP) Application Layer Gateway (ALG)) disabling on a Draytek router to prevent disruption VOIP functionality.
1) Logon to the Draytek via it’s web interface, under ‘Management’ ensure that ‘Telnet’ is enabled.
2) Use Telnet via the Windows Command Prompt. (if Telnet Client is not installed you can follow this guide
3) Issue the following commands:
sys sip_alg ?
Checks if SIP ALG is enabled or not, if it is:
sys sip_alg 0

If a draytek router has more than one connection to the internet, you will want to set a Load-Balance Policy
. This will ensure that the router uses the single connection so that only one IP address is used. It also provides fail-over if the main connection dies.
Here we have connected a new connection to WAN2 which is now to be the default connection.
