A technique for ensuring that a node that carries high-priority protocol data units and low-priority protocol data units is properly configured to accord the high-level protocol data units priority treatment is described. In accordance with the illustrative embodiment, two streams of protocol data units are transmitted through a node to be tested. One stream comprises high-priority protocol data units, and the second stream comprises low-priority protocol data units. The processing capabilities of the node are then burdened by increasing the frequency of protocol data units transmitted to it, so that the node is compelled to treat the two streams differently, if, in fact, it is properly configured to treat them differently. If the node treats the two streams differently and accords the high-priority stream higher priority, then the node is properly configured. Otherwise, the node is re-configured to accord the high-priority stream higher priority.
