What can I do if I receive an alarm indicating that the traffic rate exceeds the alarm threshold of a CE series switch

If you receive an alarm indicating that the traffic rate exceeds the alarm threshold of a CE series switch, perform the following steps to rectify the problem:

Determine the interface on which the traffic rate exceeds the alarm threshold:
1. In V100R002, an alarm indicating that the bandwidth exceeds the threshold does not display the interface name. The interface name is contained in EntityPhysicalIndex. Contact Huawei technical engineers to know the interface that generates the alarm.
2. In V100R003 and later versions, InterfaceName in an alarm message indicates the interface name.

Solution:
Run the display interface brief command and view the bandwidth usage of incoming and outgoing traffic on the interface in the last 300 seconds in the InUti/OutUti field. Perform the following operations based on actual situations:

1. If burst traffic exceeds the upper alarm threshold instantly and does not affect services, you are advised to run the trap-threshold { input-rate | outpu-rate } bandwidth-in-use [ resume-rate resume-threshold ] command in the interface view to increase the upper alarm threshold.
2. If the traffic rate on an interface remains high for a long time, you are advised to expand the link bandwidth. Determine the link bandwidth based on the traffic volume on your network to ensure that the bandwidth can be fully used and packet loss will not occur.
3. If you consider that the alarm severity is too high and want to mask this alarm, run the undo snmp-agent trap enable feature-name devm [ trap-name trap-name ] command in the system view to mask this type of alarms on all interfaces. After the alarms are masked, the switch will still record alarm messages, but does not display them.

Other related questions:
What is the alarm indicating that the number of lost I-frames in the sending direction exceeds the alarm threshold?
The alarm is generated based on the number of lost I-frames reported by the MCU. The alarm threshold is configured in the Nlogv2 configuration item in the SMC2.0 system configuration. When more than two I-frames in the sending direction are lost in 3 seconds, an alarm is generated by default.

The number of lost I-frames that are sent exceeded the alarm threshold. What can I do?
The packet loss alarm is generated based on the number of lost I-frames reported by the MCU. In the Nlogv2 configuration module on the SMC2.0 web interface, you can set the alarm threshold for the number of lost I-frames. The default alarm threshold is 2 frames/3s.

Traffic exceeds the threshold
The AR does not support query of excess traffic.

What does the alarm mean: the number of lost I-frames in the sending direction exceeds the threshold?
If an endpoint applies for two I-frames within 3s, a minor alarm is generated. If an endpoint applies for four I-frames within 3s, a major alarm is generated.
