cwaChanIdentifier

This number represents a RESOURCE at the switch that
has been assigned for this connection (identified
by ifIndex, cwaChanVpi and cwaChanVci). An example of this
resource could be the LCN/GLCN used by the switch. Another 
example could be a record number assigned for this connection 
in a database of records.
              
When a connection gets deleted, this resource gets 
released into a free pool. When a new endpoint is added
(different ifIndex, cwaChanVpi & cwaChanVci), the switch may
re-assign this resource.
              
Thus all connections in a switch would have an unique
cwaChanIdentifier. Since the number of resources in the
switch is a much lesser subset as compared to all possible
combinations of ifIndex, vpi and vci, this number serves as 
a quick reference index between the switch and the NMS.
              
This is especially useful during the configuration upload
of connections from the switch to the NMS.
