Disabling Detection of a Sudden Broadcast Traffic Volume Change in the Inbound Direction of Interfaces

Disabling Detection of a Sudden Broadcast Traffic Volume Change in the Inbound Direction of Interfaces

Context

By default, a switch checks whether the broadcast traffic volume in the inbound direction of interfaces changes suddenly. If the switch detects a sudden broadcast traffic volume change in the inbound direction of interfaces and the broadcast traffic volume exceeds the upper threshold (20000 pps), an alarm is generated, which facilitates 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 disable the function.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run set flow-change-ratio input-broadcast-detect disable

    Detection of a sudden broadcast traffic volume change in the inbound direction of interfaces is disabled.

    By default, detection of a sudden broadcast traffic volume change in the inbound direction of interfaces is enabled.
