Class CIM_PreambleFilter
extends CIM_FilterEntryBase

PreambleFilter allows the classification of packets using traffic-conditioning results (where the results are determined by a PreambleMarkerService and stored in a 'packet preamble'). This permits information about the treatment that a packet receives on an ingress interface to be communicated along with the packet to the egress interface. An instance of PreambleFilter selects packets based on a two-part string (type and value pair) identifying a specific entry in the preamble. The logic for this match is 'at least one.' That is, a packet with multiple entries/results in its preamble matches a filter if at least one of these matches the filter.

DescriptionstringTo foster interoperability, the basic format of the information captured by a PreambleMarker is specified. That information is contained in the FilterItemList property (an ordered, string array). Each entry in the array takes the form 'type,value'. When entries are added, they are appended to the end of the list. A limited set of standardized 'type's exist. They are: - ConformingFromMeter, NonConformingFromMeter and PartConformingFromMeter to convey metering results (where the 'value' is the name of the meter) - VlanId to describe the traffic's VLAN information (where the 'value' is the VLAN ID). An implementation is free to define and use other preamble 'types'. Note that a wildcard value of "any" is allowed to indicate that the preamble entry matches for any 'value' of the specified 'type'. For example, using the wildcard, an administrator can define a filter to select all packets that were found to be conforming ('type' = "ConformingFromMeter") without having to name each meter individually.
