Usage Guidelines

Usage Scenario

In default microburst detection mode, the packet sampling interval is 5 ms. In enhanced microburst detection mode, the packet sampling interval is 1 ms.

The microburst detection period is 5 minutes. That is, key performance indicators of an interface are collected every 5 minutes and related entries are generated. You can run the display qos micro-burst statistics interface interface-type interface-number command to view statistics collected within 300 minutes after microburst detection is enabled on an interface, including the average rate of burst traffic, maximum rate of burst traffic, number of discarded packets, average buffer usage on the interface, peak buffer usage on the interface, and entry generation time.

Prerequisites

The microburst detection function has been enabled on the switch by running the qos micro-burst detection [ enhanced ] enable slot slot-id command in the system view.
The microburst detection function has been enabled on an interface by running the qos micro-burst detection enable command in the interface view.

Example

# In default microburst detection mode, display microburst detection statistics on GE0/0/1.
