This read-write TruthValue specifies whether the shaper bandwidth on an Ethernet Network Port operates independently (rather than sharing/aggregating bandwidth with related shapers). Admins toggle this depending on whether they want each shaper instance to enforce its own separate cap or to jointly share a pooled bandwidth allowance with sibling shapers. For example, when provisioning multiple per-COS shapers on the same port that should each strictly enforce their own configured rate without borrowing from each other, an admin would enable cmEthernetNetPortIndependentShaperBW.
