[ no ] qos-mode-port [ low-cdv | low-latency ]
Command introduced before JunosE Release 7.1.0.
Configures an ATM port for per-port queuing. The no version restores the default
integrated mode, removing per-port queuing from the ATM port; in this state, shaping
done by the SAR is controlled by ATM.
low-cdv—HRR scheduler and SAR scheduler operate in concert. The SAR runs with
more buffering than in low-latency mode, shaping rates are driven by QoS profiles, VC
backpressure is disabled, and lenient port backpressure is enabled.
low-latency—Shaping done by the SAR is controlled by QoS. The HRR scheduler
controls the traffic rate. The SAR runs with minimal buffering, VC backpressure is
disabled, and aggressive port backpressure is enabled. This is the behavior enforced
if you do not specify an option.
