Managing Virtual Ports

This section describes the requirements and guidelines for managing the virtual ports (VPorts) on a NIC switch. This switch is provided by a network adapter that supports single root I/O virtualization (SR-IOV).

This section includes the following topics:

Creating a Virtual Port

Deleting a Virtual Port

Enumerating Virtual Ports on a Network Adapter

Querying the Parameters of a Virtual Port

Setting the Parameters of a Virtual Port

Managing the Receive Filters for a Virtual Port

Symmetric and Asymmetric Assignment of Queue Pairs

Packet Flow over a Virtual Port

Nondefault Virtual Ports and VMQ

For more information on VPorts, see Virtual Ports (VPorts).

For more information on NIC switches, see NIC Switches.

Note  Only the miniport driver for the PCI Express (PCIe) Physical Function (PF) can configure the network adapter's hardware resources, such as the VPorts. The miniport driver for the PCIe Virtual Function (VF) cannot directly access most of the SR-IOV adapter's hardware resources. For more information, see Writing SR-IOV VF Miniport Drivers.
