qos-mode-port
Syntax
[ no ] qos-mode-port [ low-cdv | low-latency ]
Release Information
Command introduced before JUNOSe Release 7.1.0.
Description
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.
Options
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.
