This attribute specifies the bandwidth pool which is to be used to
support the non-real-time variable bit rate (nrt-VBR) service
category except for connections managed by a Vpt CA. The
percentage of link capacity reserved for the given bandwidth pool is
the maximum bandwidth that can be allocated to nrt-VBR traffic.
The percentage allocated to each bandwidth pool can be
provisioned through the bandwidthPool attribute under the CA.
