The interface status changed.

Status of the interface can be :
  • block: When the rate of receiving packets is greater than the value of MaxRate and the storm control action is block, the interface status is block.
  • normal: Packets are normally forwarded.
  • error-down: When the rate of receiving packets is greater than the value of MaxRate and the storm control action is error-down, the interface status is error-down.

Impact on the System

Storms may occur if the threshold is exceeded. Services are affected.

Possible Causes

The interface traffic volume was greater than the upper threshold or less than the lower threshold.


  1. Run the display storm-control interface command to check the storm control configuration on the interface.
  2. If the interface status is error-down, check whether the interface can be enabled according to the application scenario.

    • If so, run the shutdown and undo shutdown commands manually. No further action is required.

    • If not, go to step 3.

  3. Collect alarm, log, and configuration information, and contact technical support personnel.
