CIM_Hdr8021Filter Superclass: CIM_FilterEntryBase
8021Filter allows 802.1.source and destination MAC addresses, as well as the 802.1 protocol ID, priority, and VLAN identifier fields, to be expressed in a single object to classify and identify traffic.
Qualifiers:Version ( "2.7.0" )
Parameters (local in grey)
OctetString
uint8 HdrDestMACAddr8021 [ 6 ] ;
This property is an OctetString of size 6, representing a 48-bit destination MAC address in canonical format. This value is compared to the DestinationAddress field in the MAC header, subject to the mask represented in the 8021HdrDestMACMask property. If a value for this property is not provided, then the filter does not consider 8021HdrDestMACAddr in selecting matching packets, i.e., 8021HdrDestMACAddr matches for all values.
OctetString
uint8 HdrSrcMACMask8021 [ 6 ] ;
This property is an OctetString of size 6, representing a 48-bit mask to be used in comparing the SourceAddress field in the MAC header with the value represented in the 8021HdrSrcMACAddr property. If a value for this property is not provided, then the filter does not consider 8021HdrSrcMACMask in selecting matching packets, i.e., the value of 8021HdrSrcMACAddr must match the source MAC address in the packet exactly.
uint16 HdrProtocolID8021 ;
This property is a 16-bit unsigned integer, representing an Ethernet protocol type. This value is compared to the Ethernet Type field in the 802.3 MAC header. If a value for this property is not provided, then the filter does not consider 8021HdrProtocolID in selecting matching packets, i.e., 8021HdrProtocolID matches for all values.
OctetString
uint8 HdrDestMACMask8021 [ 6 ] ;
This property is an OctetString of size 6, representing a 48-bit mask to be used in comparing the DestinationAddress field in the MAC header with the value represented in the 8021HdrDestMACAddr property. If a value for this property is not provided, then the filter does not consider 8021HdrDestMACMask in selecting matching packets, i.e., the value of 8021HdrDestMACAddr must match the destination MAC address in the packet exactly.
MinValue ( 0 )
MaxValue ( 4095 )
uint32 HdrVLANID8021 ;
This property is an 32-bit unsigned integer, representing an 802.1Q VLAN Identifier. This value is compared to the VLAN ID field in the 802.1Q header. Since the 802.1Q VLAN ID field consists of 12 bits, the values for this property are limited to the range 0..4095. If a value for this property is not provided, then the filter does not consider 8021HdrVLANID in selecting matching packets, i.e., 8021HdrVLANID matches for all values.
MinValue ( 0 )
MaxValue ( 7 )
uint8 HdrPriorityValue8021 ;
This property is an 8-bit unsigned integer, representing an 802.1Q priority. This value is compared to the Priority field in the 802.1Q header. Since the 802.1Q Priority field consists of 3 bits, the values for this property are limited to the range 0..7. If a value for this property is not provided, then the filter does not consider 8021HdrPriorityValue in selecting matching packets, i.e., 8021HdrPriorityValue matches for all values.
OctetString
uint8 HdrSrcMACAddr8021 [ 6 ] ;
This property is an OctetString of size 6, representing a 48-bit source MAC address in canonical format. This value is compared to the SourceAddress field in the MAC header, subject to the mask represented in the 8021HdrSrcMACMask property. If a value for this property is not provided, then the filter does not consider 8021HdrSrcMACAddr in selecting matching packets, i.e., 8021HdrSrcMACAddr matches for all values.
Propagated ( "CIM_ComputerSystem.Name" )
MaxLen ( 256 )
Key
string SystemName ;
The scoping ComputerSystem's Name.
boolean IsNegated ;
Boolean indicating that the match condition described in the properties of the FilterEntryBase subclass should be negated. This property is defined for ease of use when filtering on simple negations - for example, to select all source ports except 162. It is not recommended that this Boolean be set to True when filtering on multiple criteria, such as defining an IPHeadersFilter based on source/destination addresses, ports, and DiffServ Code Points.

ArrayType ( "Indexed" )
string StatusDescriptions [ ] ;
Strings describing the various OperationalStatus array values. For example, if 'Stopping' is the value assigned to OperationalStatus, then this property may contain an explanation as to why an object is being stopped. Note that entries in this array are correlated with those at the same array index in OperationalStatus.

uint16 OperationalStatus [ ] ;
Indicates the current status(es) of the element. Various health and operational statuses are defined. Many of the enumeration's values are self- explanatory. However, a few are not and are described in more detail.
'Stressed' indicates that the element is functioning, but needs attention. Examples of 'Stressed' states are overload, overheated, etc.
'Predictive Failure' indicates that an element is functioning nominally but predicting a failure in the near future.
'In Service' describes an element being configured, maintained, cleaned, or otherwise administered.
'No Contact' indicates that the monitoring system has knowledge of this element, but has never been able to establish communications with it.
'Lost Communication' indicates that the ManagedSystem Element is known to exist and has been contacted successfully in the past, but is currently unreachable.
'Stopped' and 'Aborted' are similar, although the former implies a clean and orderly stop, while the latter implies an abrupt stop where the element's state and configuration may need to be updated.
'Dormant' indicates that the element is inactive or quiesced.
'Supporting Entity in Error' describes that this element may be 'OK' but that another element, on which it is dependent, is in error. An example is a network service or endpoint that cannot function due to lower layer networking problems.
'Completed' indicates the element has completed its operation. This value should be combined with either OK, Error, or Degraded so that a client can till if the complete operation passed (Completed with OK), and failure (Completed with Error). Completed with Degraded would imply the operation finished, but did not complete OK or report an error.
'Power Mode' indicates the element has additional power model information contained in the Associated PowerManagementService association.
OperationalStatus replaces the Status property on ManagedSystemElement to provide a consistent approach to enumerations, to address implementation needs for an array property, and to provide a migration path from today's environment to the future. This change was not made earlier since it required the DEPRECATED qualifier. Due to the widespread use of the existing Status property in management applications, it is strongly RECOMMENDED that providers/instrumentation provide BOTH the Status and OperationalStatus properties. Further, the first value of OperationalStatus SHOULD contain the primary status for the element. When instrumented, Status (since it is single-valued) SHOULD also provide the primary status of the element.
MappingStrings { "MIF.DMTF|ComponentID|001.5" }
datetime InstallDate ;
A datetime value indicating when the object was installed. A lack of a value does not indicate that the object is not installed.

string Status ;
A string indicating the current status of the object. Various operational and non-operational statuses are defined. This property is deprecated in lieu of OperationalStatus, which includes the same semantics in its enumeration. This change is made for 3 reasons: 1) Status is more correctly defined as an array. This overcomes the limitation of describing status via a single value, when it is really a multi-valued property (for example, an element may be OK AND Stopped. 2) A MaxLen of 10 is too restrictive and leads to unclear enumerated values. And, 3) The change to a uint16 data type was discussed when CIM V2.0 was defined. However, existing V1.0 implementations used the string property and did not want to modify their code. Therefore, Status was grandfathered into the Schema. Use of the Deprecated qualifier allows the maintenance of the existing property, but also permits an improved definition using OperationalStatus.
MaxLen ( 64 )
string Caption ;
The Caption property is a short textual description (one- line string) of the object.
string Description ;
The Description property provides a textual description of the object.
string ElementName ;
A user-friendly name for the object. This property allows each instance to define a user-friendly name in addition to its key properties, identity data, and description information.
Note that the Name property of ManagedSystemElement is also defined as a user-friendly name. But, it is often subclassed to be a Key. It is not reasonable that the same property can convey both identity and a user-friendly name, without inconsistencies. Where Name exists and is not a Key (such as for instances of LogicalDevice), the same information can be present in both the Name and ElementName properties.
