This object configures the congestion loss priority (CLP) threshold for Cell Loss Priority class 0 and 1 combined traffic on non-real-time variable bit rate (nrt-VBR) virtual circuits in shared memory, controlling how much buffer space is allocated before tail-drop discarding begins. The value must be a multiple of 16 bytes and must exceed the separate CLP=1 threshold but not exceed 4080 bytes. Network administrators tune this to balance throughput and latency for streaming or bursty VBR traffic.
