The set flow-change-ratio input-broadcast-detect disable command disables detection of a sudden broadcast traffic volume change in the inbound direction of interfaces.
The undo set flow-change-ratio input-broadcast-detect disable command enables detection of a sudden broadcast traffic volume change in the inbound direction of interfaces.
By default, detection of a sudden broadcast traffic volume change in the inbound direction of interfaces is enabled.
set flow-change-ratio input-broadcast-detect disable
undo set flow-change-ratio input-broadcast-detect disable
Usage Scenario
By default, the switch checks whether the volume of broadcast traffic in the inbound direction of interfaces changes suddenly, and generates a trap after detecting a sudden change, facilitating network maintenance.
If the switch has many interfaces, detection of a sudden broadcast traffic volume change in the inbound direction of interfaces consumes some CPU and memory resources. You can run the set flow-change-ratio input-broadcast-detect disable command to disable the function.
Precautions
If the system software is upgraded from V200R009C00 or an earlier version to V200R010C00 or a later version, detection of a sudden broadcast traffic volume change in the inbound direction of interfaces is disabled by default.
