Use the PC to ping the NE40E. The delay is very short.
Change the interface and use the PC to ping the non-Huawei router. The delay ranges from 330 ms to 400 ms.
Change the slot and use the PC to ping the non-Huawei router. The delay ranges from 330 ms to 400 ms.
Check the interface configuration and the configuration is shown as follows.

The preceding configuration shows that the PIR of the traffic in the BE queue is 3%, that is, the peak information rate is 61.44 kbit/s (2.048 Mbit/s × 3%). When the PC pings the non-Huawei router by sending 3000-byte packets, the delay is about 3000 × 8/61440=390 ms.
Try to modify the PIR configuration and set the value to 100%. After the configuration, the delay of pinging is resumed. The configuration is as follows.
port-queue be wfq shaping cir percentage 2 pir percentage 100
Why is the delay normal when the NE40E pings 18.104.22.168 of the non-Huawei router?
The reason is that when the NE40E initiates the ping operation, the NE40E itself generates packets. These packets enter the CS7 queue for PQ scheduling. The bandwidth for traffic in the PQ queue is 2 Mbit/s. Therefore, the delay in this case is normal.
