10 . The uplink port profiles must be selected. Click the Add button and then select
Existing Uplink Port Profile (because you’ve already created the profile—but note
that it is also possible to create a new uplink port profile). Click OK. Multiple
uplink port profiles can be added as required. Click Next.
11 . Click Finish to create the logical switch.
CONFIGURING A HYPER-V HOST WITH A LOGICAL SWITCH
The final step is to configure Hyper-V hosts with the logical switch, which will trigger
SCVMM to create virtual switches on the Hyper-V host that matches the
configurations defined. It also sets up the environment for virtual machine and
service deployments, and all of the networking elements will be configured
automatically.
In my lab, my Hyper-V hosts have two 10Gbps network adapters that I wish to have
teamed (using SET) to use for my Hyper-V virtual switch. I also have a separate
network adapter for management actions such as RDP and file services and another
network adapter for cluster and Live Migration operations. I don’t use iSCSI or SMB in
this environment because it uses Fibre Channel to connect to a SAN. I’m noting this
so that you understand my choices in the following procedure. However, if you need
the virtual switch to use all of your network adapters, including your management
network adapter, SCVMM can take care of ensuring that you don’t lose connectivity,
which I cover in the following walk-through.
1 . Open Virtual Machine Manager.
2 . Open the Fabric workspace.
3 . Navigate to your Hyper-V hosts under Servers ➣ <host group>.
4 . Right-click a Hyper-V host and choose Properties.
5 . Click the Virtual Switches tab, and click the New Virtual Switch button. The option
to create a new logical switch or a new standard switch is displayed. Click the New
Logical Switch option.
6 . In this walk-through, only one logical switch was created, and that will be selected
automatically along with one network adapter. This network adapter can be
changed by using the drop-down, as can the uplink port profile it uses. Additional
network adapters can be added by using the Add button if you wish to create a
team.
In most environments, the uplink port profile needs to be the same for all network
adapters. SCVMM will perform a check and gray out the option to change the
uplink port profile for any additional network adapters, as shown in Figure 3.27.
Some third-party forwarder switch extensions do allow different connectivity for
different adapters in a team, which SCVMM would detect if configured for the
logical switch, and the option to set different virtual port profiles was enabled.
