What is the LLQ queue on an AR
A low latency queuing (LLQ) queue is a special EF queue. Compared with EF, LLQ provides shorter delay, which provides good QoS assurance for delay-sensitive services such as VoIP services. An EF queue has the highest priority. You can put one or more types of packets into EF queues and set different bandwidth for different types of packets. During packet scheduling, packets in the EF queues are scheduled first to ensure low latency. When traffic is congested on an interface, packets in the EF queues are sent first. To ensure scheduling for low-priority queues (such as AF or BE queues), rate limiting is configured for EF queues. When traffic is not congested on the interface, EF queues can use the idle bandwidth of AF or BE queues. Therefore, packets in EF queues can obtain idle bandwidth, and does not occupy the bandwidth that exceeds the specifications.

What does shaping active in the Enqueue field mean
If Shaping Active is in the Enqueue field, traffic shaping is configured in the traffic policy.
  • -The value Shaping Active:NO indicates that traffic does not exceed the traffic shaping threshold. Traffic shaping is not performed.
  • -The value Shaping Active:YES indicates that traffic has exceeded the traffic shaping threshold. Traffic shaping has been performed.

Do CE series switches support collection of queue-based multicast traffic statistics
Currently, CE12800 series switches do not support collection of queue-based multicast traffic statistics. CE8800&7800&6800&5800 series switches support collection of queue-based multicast traffic statistics. Currently, CE12800 series switches support collection of only queue-based unicast traffic statistics. You can run the display qos queue statistics interface interface-type interface-number command in any view to view queue-based unicast traffic statistics on an interface.
