Types of NDIS Ports

NDIS ports can be one of the following types:

NdisPortTypeUndefined
The default port type. Use this type for general port applications that do not fit into one of the following types.

NdisPortTypeBridge
Reserved for system use.

NdisPortTypeRasConnection
A Remote Access Service (RAS) connection.

NdisPortType8021xSupplicant
A remote wireless station that is associated with an access point on this host computer.

NdisPortTypeNdisImPlatform
Reserved for system use.

Note This value is supported only in NDIS 6.30 and later.

The characteristics of an NDIS port vary from one port application to another. For example, for a bridge interface, the miniport driver upper edge of an intermediate driver creates an NdisPortTypeBridge port when the protocol edge of the intermediate driver binds to a physical miniport adapter that requires a bridge at layer three.
