Configuring Storm Control

Configuring Storm Control


To limit the rate of excess broadcast, multicast or unknown unicast packets, configure storm control on the interface that receives these packets.

Pre-configuration Tasks

Before configuring the storm control function, complete the following tasks:

Configure link layer protocol parameters for interfaces to ensure that the link protocol status on the interfaces is Up.


  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. Run storm-control { broadcast | multicast | unicast } min-rate min-rate-value max-rate max-rate-value

    Storm control is performed on broadcast packets, multicast packets, or unknown unicast packets on the interface.

    By default, storm control is disabled on the interface.

  4. Run storm-control action { block | error-down }

    The storm control action is configured.

    By default, no storm control action is configured.

  5. (Optional) Run storm-control enable { log | trap }

    The function of recording logs or reporting traps during storm control is enabled.

    By default, the device is disabled from recording logs or reporting traps.

  6. (Optional) Run storm-control interval interval-value

    The storm detection interval is configured.

    By default, the storm detection interval is 5s.

Verifying the Configuration

Run the display storm-control [ interface interface-type interface-number ] command to check the storm control configuration on an interface.

Follow-up Procedure

If an interface is in Error-Down state, you are advised to determine the cause first.

An interface in Error-Down state can be recovered using either of the following methods:
  • Manual recovery (after an Error-Down event occurs):

    If a few interfaces need to be recovered, run the shutdown and undo shutdown commands in the interface view. Alternatively, run the restart command in the interface view to restart the interfaces.

  • Automatic recovery (before an Error-Down event occurs):

    If a large number of interfaces need to be recovered, manual recovery is time consuming and some interfaces may be omitted. To avoid this problem, run the error-down auto-recovery cause storm-control interval interval-value command in the system view to enable automatic interface recovery and set the recovery delay time. Run the display error-down recovery command to view information about automatic interface recovery.


    This method does not take effect on interfaces that are already in Error-Down state. It is effective only on interfaces that enter the Error-Down state after this configuration is complete.
