Guaranteed service type

Specifies an alternate link layer (Layer-2) priority value for packets with the Guaranteed service type (ServiceTypeGuaranteed). The Packet Scheduler inserts the corresponding priority value in the Layer-2 header of the packets.

If you enable this setting, you can change the default priority value associated with the Guaranteed service type.

If you disable this setting, the system uses the default priority value of 0.

Important: If the Layer-2 priority value for this service type is specified in the registry for a particular network adapter, this setting is ignored when configuring that network adapter.

Supported on: At least Windows Server 2003 operating systems or Windows XP Professional
