This attribute is HISTORICAL. Please refer to the attribute of the
same name in the group AtmTmOper.
This attribute shows the amount by which the bandwidth has been
reduced for this connection. This value is non-zero only for
connections which have bandwidthElastic displayed as yes, and
which are also operating in a reduced bandwidth mode. This is
typically be the case for selected connections running over an IMA
link. This attribute takes a value from 0 (no reduction) up to the
ECR. All connections which are running at their full allocated
bandwidth, bwReduction have the value 0. Connections which have
been reduced in allocated bandwidth have a positive number for this
attribute. The bwReduction may be subtracted from the ECR (which
is displayed as txTrafficDescParm 5) to determine the actual
bandwidth allocated to this connection.
