This read-write TruthValue enables or disables cut-through switching for a given priority on a given interface, serving as the general per-interface, per-priority control described alongside the specific rlIfCutPriorityZero through Seven objects. It matters as the parameterized mechanism admins would use to configure cut-through per priority across many interfaces without eight separate scalar objects per port. For example, an SNMP management application would use this indexed object to programmatically toggle cut-through for a specific priority on a specific interface in a single set operation.
