Properties

The MSFT_NetOffloadGlobalSetting class has these properties.

Caption
Data type: string
Access type: Read-only

Contains a short textual description of the object.

This property is inherited from CIM_ManagedElement.

Chimney
Data type: uint8
Access type: Read/write

Whether to turn on TCP chimney offload. For information on TCP chimney offload, see TCP Chimney Offload.

ValueMeaning
Disabled
0

TCP chimney offload is turned off.

Enabled
1

TCP chimney offload is turned on.

Automatic

Description
Data type: string
Access type: Read-only

Provides a textual description of the object.

This property is inherited from CIM_ManagedElement.

ElementName
Data type: string
Access type: Read-only
Qualifiers: Required, Override ("ElementName")

The user-friendly name for this instance. In addition, the user-friendly name can be used as an index property for a search or query. (Note: The name does not have to be unique within a namespace.)

This property is inherited from CIM_SettingData.

InstanceID
Data type: string
Access type: Read-only
Qualifiers: key, Override ("InstanceID")

Uniquely and opaquely identifies an instance of this class within the scope of the containing Namespace.

Important  In order to ensure uniqueness within the Namespace, the value of InstanceID should be constructed in the following pattern:

OrgID:LocalID

OrgID must include a copyrighted, trademarked or otherwise unique name that is owned by the business entity defining the InstanceID, or be a registered ID that is assigned by a recognized global authority. This is similar to the structure of Schema class names. In addition, to ensure uniqueness the first colon in InstanceID must be between the OrgID andLocalID. Therefor the OrgID must not contain a colon (':').

LocalID is chosen by the business entity and should not be re-used to identify different underlying real-world elements.

If the preceding pattern is not used, the defining entity must assure that the resultant InstanceID is not re-used across any InstanceIDs produced by this or other providers for this Namespace.

For Distributed Management Task Force (DMTF) defined instances, the pattern must be used with the OrgID set to CIM.

 

This property is inherited from CIM_SettingData.

NetworkDirect
Data type: uint8
Access type: Read/write

Whether to turn on NetworkDirect.

ValueMeaning
Disabled
0

NetworkDirect is turned off.

Enabled
1

NetworkDirect is turned on.

 

NetworkDirectAcrossIPSubnets
Data type: uint8
Access type: Read/write

Whether to allow NetworkDirect connectivity outside of the local IP subnet.

ValueMeaning
Blocked
0

NetworkDirect connectivity outside of the local IP subnet is not allowed.

Allowed
1

NetworkDirect connectivity outside of the local IP subnet is allowed.

 

PacketCoalescingFilter
Data type: uint8
Access type: Read/write

Whether to turn on packet coalescing filters. For information about packet coalescing, see NDIS Packet Coalescing.

ValueMeaning
Disabled
0

Packet coalescing filters are turned off.

Enabled
1

Packet coalescing filters are turned on.

 

ReceiveSegmentCoalescing
Data type: uint8
Access type: Read/write

Whether to turn on receive segment coalescing (RSC). For information about RSC, see Receive Segment Coalescing.

ValueMeaning
Disabled
0

RSC is turned off.

Enabled
1

RSC is turned on.

 

ReceiveSideScaling
Data type: uint8
Access type: Read/write

Whether to turn on receive side scaling (RSS). For more information about RSS, see Receive Side Scaling.

ValueMeaning
Disabled
0

RSS is turned off.

Enabled
1

RSS is turned on.

 

TaskOffload
Data type: uint8
Access type: Read/write

Whether to turn on TCP/IP task offload. For information about TCP/IP task offload, see TCP/IP Task Offload.

ValueMeaning
Disabled
0

TCP/IP task offload is turned off.

Enabled
1

TCP/IP task offload is turned on.
