qos micro-burst detection enable
Function
The qos micro-burst detection enable command enables microburst detection.
The undo qos micro-burst detection enable command disables microburst detection.
By default, microburst detection is disabled on a switch and interfaces.

Usage Guidelines
Usage Scenario
To detect microbursts on an outbound interface, you must enable microburst detection on a switch and interfaces. This helps locate packet loss caused by microbursts.
In default microburst detection mode, the packet sampling interval is 5 ms. In enhanced microburst detection mode, the packet sampling interval is 1 ms.
Precautions
Before enabling microburst detection on an interface, you must enable this function on the slot where the interface resides.
In default microburst detection mode, microburst detection can be enabled on multiple interfaces on a switch. In enhanced microburst detection mode, microburst detection can be enabled on only one interface on a switch.
To change the mode of microburst detection, you must delete the existing microburst detection configuration from the switch.
