Configuring Dynamic vNIC Connection Policies
Dynamic vNIC Connection Policy
Note | In an SR-IOV topology, such as a Hyper-V or KVM cluster, a Virtual Function (VF) takes the place of the dynamic vNIC. The VF is essentially a restricted version of the dynamic vNIC, in which all system communication and configuration of the VF is performed through the associated physical function (PF). |
The dynamic vNIC connection policy determines how the connectivity between VMs and dynamic vNICs is configured. This policy is required for Cisco UCS domains that include servers with VIC adapters on which you have installed VMs and configured dynamic vNICs.
Ethernet Adapter Policy
Each dynamic vNIC connection policy includes an Ethernet adapter policy and designates the number of vNICs that can be configured for any server associated with a service profile that includes the policy.
For KVM, use the predefined Ethernet adapter policy named Linux.
Server Migration
Note | If you migrate a server that is configured with dynamic vNICs, the dynamic interface used by the vNICs fails and notifies you of that failure. When the server comes back up, assigns new dynamic vNICs to the server. If you are monitoring traffic on the dynamic vNIC, you must reconfigure the monitoring source. |

Creating a Dynamic vNIC Connection Policy
Changing a Dynamic vNIC Connection Policy
Step 1 | In the Navigation pane, click LAN. | ||||||||||
Step 2 | Expand . | ||||||||||
Step 3 | Expand the node
for the organization that contains the policy that you want to change.
If the system does not include multitenancy, expand the root node. | ||||||||||
Step 4 | Expand the Dynamic vNIC Connection Policies node and click the policy that you want to change. | ||||||||||
Step 5 | In the Work pane, click the General tab. | ||||||||||
Step 6 | Change one or
more of the following fields:
You cannot change the other properties of the policy, such as the Name field. | ||||||||||
Step 7 | Click Save Changes. | ||||||||||
Step 8 | If a confirmation dialog box displays, click Yes. |
Deleting a Dynamic vNIC Connection Policy
You can delete a dynamic vNIC connection policy.
Viewing Dynamic vNIC Properties in a VM
You can view dynamic vNIC properties in a VM.
The VM must be operational.
Step 1 | In the Navigation pane, click VM. |
Step 2 | On the VM tab, expand . |
Step 3 | Expand Virtual Machines. |
Step 4 | Expand the virtual machine that contains the dynamic vNIC. |
Step 5 | Choose the dynamic vNIC. |
Step 6 | In the
Work pane, click the
General tab.
In the Properties area, the vNIC properties appear. |
