HVN(4)                  NetBSD Kernel Interfaces Manual                 HVN(4)


NAME

     hvn -- Hyper-V networking interface


SYNOPSIS

     hvn* at vmbus?


DESCRIPTION

     The hvn driver provides support for a Network Virtual Service Client
     (NetVSC), a virtual networking interface that relays device requests to
     the Virtual Service Provider (VSP) in the management operating system via
     the VMBus.

     NetVSC emulates an RNDIS 1.0 compliant device on top of a custom NVS pro-
     tocol operating over the VMBus channel ring.

     Individual networking interfaces can be renamed by issuing a
     Rename-VMNetworkAdapter PowerShell command in the management domain.  In
     order to enable sending and receiving of IEEE 802.1q (VLAN) frames, the
     virtual port needs to be put into Trunk mode with the
     Set-VMNetworkAdapterVlan command.
