SECE/4/STORMCTRL_IF_ERROR_DOWN

SECE/4/STORMCTRL_IF_ERROR_DOWN

Message

SECE/4/STORMCTRL_IF_ERROR_DOWN:Interface [STRING] is error-down for storm-control.

Description

The storm control function was configured, and a broadcast storm occurred on the interface. As a result, the interface status became Error-Down.

Parameters

Parameter Name Parameter Meaning

[STRING]

Indicates the interface name.

Possible Causes

The storm control function was configured on the interface, and the storm control action was set to error-down. A broadcast storm occurred due to a loop, attack, or hardware fault, and the average rate of broadcast, multicast, or unknown unicast packets exceeded the upper threshold. As a result, the storm control action was performed and the interface status became Error-Down.

Procedure

  1. Check whether the broadcast storm is caused by a loop. If so, remove the loop. For the broadcast storm troubleshooting procedure, see MAC Address Flapping Occurs on a Layer 2 Network and STP Faults Occur in the Revelations of Troublesolving.
  2. Run shutdown and undo shutdown commands in sequence on the interface. If many interfaces are in Error-Down state, run the error-down auto-recovery cause storm-control interval interval-value command in the system view to enable these interfaces to go Up and set a recovery delay. Then run the display error-down recovery command to check whether there are still interfaces in Error-Down state.
