SECE/4/STRACK_ERROR_DOWN: Interface's status is changed to error-down because an attack is detected. Interface=[OCTET].


An interface transitions to error-down state because an attack is detected on the interface.


Parameter Name Parameter Meaning
Interface Indicates the interface that receives attack packets.

Possible Causes

The attack tracing module detects an attack, and the attack defense action is set to error-down.


  1. Check whether the discarded packets are sent from an authorized user.
  2. If the sender is an authorized user, run the auto-defend whitelist whitelist-num { acl acl_number | interface interface-type interface-number } command to add the user to the whitelist. Then packets sent from this user are not discarded.
  3. If the sender is an attacker, you do not need to perform any operation.
