This read-create RowStatus column creates or deletes a row in the bandwidth availability parameters table, and requires the traffic class, delta bandwidth, and both operational and administrative idleSlope objects to already be set before the row can be made active(1); once active, the traffic class value itself can no longer be changed. Admins use it when provisioning credit-based shaper support for a new traffic class on a port, following the required set-then-activate sequence. For example, an admin adding shaper support for a new traffic class would first set the traffic class and bandwidth values in the same row, then set this object to active(1) to bring the row into effect.
