How to Configure Network Settings on a Host by Applying a Logical Switch in System Center 2012 SP1

1. Open the Fabric workspace.

2. In the Fabric pane, expand Servers, expand All Hosts, and then locate and click the host group where the host resides.

3. In the Hosts pane, click the host that you want to configure.

4. On the Host tab, in the Properties group, click Properties.

5. In the Host Name Properties dialog box, click the Hardware tab.

6. Under Network Adapters, click the physical network adapter that you want to configure. If you want to use this network adapter for virtual machines, ensure that the Available for placement check box is selected. If you want to use this network adapter for communication between the host and the VMM management server, ensure that the Used by management check box is selected.

Important

Make sure that you have at least one network adapter that is available for communication between the host and the VMM management server, and that Used by management is selected for this network adapter. If you have already applied a logical switch and an uplink port profile to a network adapter, if you click Logical network connectivity, you can see the resulting connectivity. However, if you plan to apply a logical switch and an uplink port profile, do not make individual selections in Logical network connectivity. Instead, use the following procedure.

1. Open the Fabric workspace.

2. In the Fabric pane, expand Servers, expand All Hosts, and then locate and click the host group that contains the host.

3. In the Hosts pane, click the host that you want to configure.

4. On the Host tab, in the Properties group, click Properties.

5. In the Host Name Properties dialog box, click the Virtual Switches tab.

6. On the Virtual Switches tab, do the following:

   1. Select an existing logical switch from the list, or click New Virtual Switch and then click New Logical Switch.
      
      
   2. In the Logical switch list, select the logical switch that you want to use.
      
      
   3. Under Adapter, select the physical adapter that you want to apply the logical switch to.
      
      
   4. In the Uplink Port Profile list, select the uplink port profile that you want to apply. The list contains the uplink port profiles that have been added to the logical switch that you selected. If a profile seems to be missing, review the configuration of the logical switch and then return to this property tab.
      
      
   5. As needed, repeat the steps for creating a new logical switch.
      
      

      Important

      If you apply the same logical switch and uplink port profile to two or more adapters, the two adapters might be teamed, depending on a setting in the logical switch. To find out if they will be teamed, open the logical switch properties, click the Uplink tab, and view the Uplink mode setting. If the setting is Team, the adapters will be teamed. The specific mode in which they will be teamed is determined by a setting in the uplink port profile.

   6. When you have finished configuring settings, click OK.
      
      

      Caution
      While VMM creates the virtual switch, the host may temporarily lose network connectivity. This may have an adverse effect on other network operations in progress.

If certain network optimization capabilities are available on a host that is running Windows Server 2008 R2 or Windows Server 2012, VMM automatically detects the capabilities and displays a message. These capabilities are Virtual Machine Queue (VMQ) and TCP Chimney Offload. After VMM has detected that either or both of these capabilities are available, in the Host Properties dialog box, the Virtual switches tab will display the message Network optimization is available on this virtual switch. For information about these network optimization capabilities, see Using TCP Chimney Offload and Using Virtual Machine Queue. For information about these network optimization capabilities in the context of VMM, see the “Network Optimization Support” section in Configuring Virtual Networks in VMM (which describes the capabilities in an earlier version of VMM).

1. Open the Fabric workspace.

2. In the Fabric pane, expand Networking, and then click Logical Networks.

3. On the Home tab, in the Show group, click Hosts.

4. In the Logical Network Information for Hosts pane, expand the host, and then click a network adapter.

5. In the Network Compliance column, view the compliance status.

   • A value of Fully compliant indicates that the settings on the host are consistent with the configuration in VMM. For example, Fully compliant indicates that all IP subnets and VLANs that are included in the network site are assigned to the network adapter.
     
     
   • A value of Partially compliant indicates that there is only a partial match between the settings on the host and the configuration in VMM.
     
     In the details pane, the Logical network information section lists the assigned IP subnets and VLANs for the network adapter. If an adapter is partially compliant, you can view the reason in the Compliance errors section.
     
     
   • A value of Non compliant indicates that the settings on the host are missing from the configuration in VMM. For example, Non compliant indicates that none of the IP subnets and VLANs that are defined for the logical network are assigned to the physical adapter.
     
     

   Tip
   In addition to the compliance information, you can also view detailed information about the network adapter, such as the assigned IP address and MAC address, and the associated virtual networks.
