Obsolete scalar object returns the index of the next available row in
the usdTrafficShapeProfileTable. This object returns a value of zero
when it is the lexicographic successor of a varbind presented in an SNMP
GETNEXT or GETBULK request, for which circumstance it is assumed that
index allocation is unintended. This object became obsolete when the
policy shaper capability was moved into the quality of service
component.
