Description: The MIB module for managing Cisco medianet flow metadata.
Metadata, in the simplest form, is data that qualifies 
other data. Flow metadata is data that describes a flow 
in the network. Metadata plays an important role in providing
a framework, that makes data from one component available to
another component on the same network element as well as 
across other network elements.

        MIB Table Overview:
        ===================
This MIB consists of two tables: 

  1) cfmMetadataFlowTable
  2) cfmMetadataFlowAttrTable

cfmMetadataFlowTable provides the details about the six tuple 
which can uniquely identify a network traffic flow. 

cfmMetadataFlowAttrTable will specify flow attributes  carried
in the metadata flow. Flow attribute values are 
represented in  'Type-Value' format.

cfmMetadataFlowAttrType - Represent the type of flow attribute.
cfmMetadataFlowAttrValue - Represent corresponding flow
                           attribute value.

cfmMetadataFlowTable and cfmMetadataFlowAttrTable are linked
together using flow ID which will map respective metadata flow
attributes with the corresponding flow key.
