Microsoft SCVMM Networking 
This section introduces some Microsoft SCVMM concepts that are relevant to Cisco Nexus 1000V and its 
integration with Microsoft SCVMM. For detailed information about Microsoft SCVMM networking, please refer to 
the Microsoft documentation. 
Switch Extension Managers 
Microsoft SCVMM views third-party applications such as the Cisco Nexus 1000V VSM as configuration providers. 
Before the Cisco Nexus 1000V VSM is used as a forwarding extension in a Microsoft Hyper-V switch, the VSM 
must be registered with Microsoft SCVMM as a virtual switch extension manager (VSEM). After the VSM is 
registered as a VSEM, Microsoft SCVMM imports all configurations defined by the VSM administrator on the Cisco 
Nexus 1000V. 
A VSEM is created by connecting to the VSM management IP address and the switch administrator credentials. In 
Figure 3, a Cisco Nexus 1000V VSM is being added as a VSEM by connecting to the switch management IP 
address of 10.10.1.10 using HTTP. A RunAs account called VSM Admin has been created using the switch 
administrator credentials.
