The value of vRtrRsvpDSTETeClassClassType indicates the class
type (CT) associated with the TE class. Both
vRtrRsvpDSTETeClassClassType and vRtrRsvpDSTETeClassPriority need
to be set in the same PDU for a row to be created. A value of -1
indicates that the CT for this TE class is invalid and hence the
TE class is considered as not configured.
