The value of this object specifies the type
of shared shaping that is to be performed when
shared shaping is enabled. Shared shaper types
are defined as follows:
'simple' indicates that Simple Shared Shaping is
performed regardless of the line cards capabilities.
'compound' indicates that Compound Shared Shaping is
to be performed. When compound is specified for a line
card that does not support Compound Shared Shaping, a
warning message is logged, and Simple Shared Shaping
is configured instead.
'auto' indicates that selection of the shared shaper
should be automatic such that compound shared shaping
is performed on line cards which support it and simple
shared shaping is performed on line cards that do not
support it.
