This read-create boolean enables or disables the frame discard feature for this connection, applicable only on the master endpoint and only for VCC, not VPC, connections. An admin enables this so that, under congestion, the switch discards entire AAL5 frames rather than partial frames, preserving frame integrity for protocols where a partially delivered frame is worse than a dropped one. For example, on a VCC carrying frame-based data traffic prone to congestion, the admin would enable frame discard on the master endpoint to avoid sending corrupted partial frames downstream when cells must be dropped.
