This attribute allows the link rate to be overridden for this interface.
This allows the user to specify a value other than the actual physical
link rate computed when a Framer component is provisioned. In
the absence of a Framer component, or when a VirtualFramer
component is provisioned, this value needs to be explictly set to
provide an equivalent link rate.
This attribute provides control on the amount of bandwidth
available for performing CAC. This attribute also provides the
requested amount of bandwidth that is negotiated across an ATM
network for traffic conversion polices 3 and 4, since these policies
are a function of the access rate.
