Network Segmentation Manager
This chapter describes how to identify and resolve problems with Network Segmentation Manager (NSM).
Information About Network Segmentation Manager
For information on the Network Segmentation Manager, see the Cisco Nexus 1000V for Hyper-V Network Segmentation Manager Configuration Guide.
Updating VM Fails
This problem usually occurs when you are trying to attach a vEth port to the Cisco Nexus 1000V and Microsoft SCVMM server.
Step 1 Launch the Microsoft SCVMM UI.
Step 2 Verify the sytem flags on the network segment and port profile on the Virtual Supervisor Module (VSM) by entering the following commands:
- show run port-profile port-profile-name
- show nsm network segment name name
Step 3 Repair the VM from the Microsoft SCVMM by running the repair option followed by ignore.
Step 4 Once the operation is complete, refresh the VM.
Step 5 Move the vEth port to the Not Connected state from the Microsoft SCVMM.
Step 6 Attach the vEth port to the Microsoft SCVMM using one of the following combinations:
- Choose System Network Segment > System Port Profile
- Chose System Network Segment > Non System Port Profile
Choose Non System Network Segment > Non System Port Profile
Network Segment Not Visible on the Microsoft SCVMM
When creating a VM network on a Microsoft SCVMM using a network segment from a Cisco Nexus 1000V device, the network segment cannot be found. This problem can occur due to one of the following reasons:
- The network segment is in the unpublished state.
- A Switch Extension Manager refresh was not performed after creating the network segment.
Step 1 Launch the Microsoft SCVMM UI.
Step 2 From theVSM, verify the network segment configuration by entering the show nsm network segment name command:
Step 3 Verify that the network segment has a publish-name.
Step 4 After completing Step 3, choose Fabric > Switch Extension Manager/Network Service > Extension, and choose Refresh to update the Microsoft SCVMM with the latest VSM configuration.

Network Segment Is Not Available on the Microsoft SCVMM
When you apply a VM network on a Microsoft SCVMM to a Cisco Nexus 1000V vNIC, a network error is displayed.
Step 1 On the Microsoft SCVMM, identify the network segment used to create the VM network.
Step 2 On the VSM, identify the network segment pool to which the network segment is associated.
Step 3 Identify the uplink networks that allow the network segment pool identified in Step 2.
Step 4 On the Microsoft SCVMM, verify that the logical switch on that host is using the uplink networks identified in Step 3.
Step 5 If the links do not agree, change the appropriate uplink networks as needed.
