Is the upper or lower threshold for the traffic shaping rate in the adaptive traffic profile used by default

1

The upper threshold for the traffic shaping rate is used by default. The system then dynamically adjust traffic shaping parameters based on the NQA result.

Why the interval at which the traffic shaping rate increases can be set in an adaptive traffic profile of an AR, but the interval at which the traffic shaping rate decreases cannot be set
An adaptive traffic profile on an AR does not support the configuration of the interval at which the traffic shaping rate decreases. When an NQA test instance detects that the packet loss rate is greater than the upper limit configured in the adaptive traffic profile, the traffic shaping rate of the interface needs to be reduced immediately. This ensures that the traffic shaping rate is rapidly adapted to the network in order to prevent data loss.

What is the operating temperature of boards and what are the upper and lower temperature thresholds
You can use the display temperature command to view the current card temperature and temperature alarm thresholds. In the command output, the Temperature.(C) field shows the current card temperature, the Upper field shows the upper temperature alarm threshold , and the Lower field shows the lower temperature alarm threshold. In a poorly ventilated environment, temperature alarms may be generated frequently because the card temperature is high and the upper temperature alarm threshold is small. To avoid this problem, clean the air filter of the device or increase the upper temperature alarm threshold. NOTE: The temperature thresholds are preset and you do not need to change them. If you have special requirements on the temperature, contact Huawei engineers.

Can the adaptive traffic profile be bound to an NQA test instance
The adaptive traffic profile can be bound to an NQA test instance. The upstream device uses the upper threshold for the traffic shaping rate in the adaptive traffic profile if the adaptive traffic profile is not bound to the NQA test instance.

What Are Differences Between the Outbound Traffic Policing and Traffic Shaping
Both outbound traffic policing (TP) and traffic shaping (TS) limit the rate of outgoing traffic on an interface. Traffic policing and traffic shaping have the following differences: -Traffic policing directly discards packets with rates that are greater than the traffic policing rate. Traffic shaping, however, buffers packets with rates that are greater than the traffic shaping rate and sends the buffered packets at an even rate. -Traffic shaping increases the delay, whereas traffic policing does not.

The interval at which the traffic shaping rate increases can be set, but the interval at which the traffic shaping rate decreases cannot be set. Why
When the NQA test instance detects that the packet loss ratio is greater than the upper threshold in the adaptive traffic profile, the upstream device reduces the traffic shaping rate. This ensures that the traffic shaping rate rapidly adapt to the network and prevents data loss.
