Alarm ID Alarm Severity Alarm Type Warning securityServiceOrMechanismViolation(10)


Name Meaning
OID Indicates the ID of the MIB object.
Interface Indicates the access interface of the attacker.

Impact on the System

The interface in error-down state cannot work.

Possible Causes

The device received a large number of packets from the interface, and the number of received packets exceeded the threshold for identifying an attack. Therefore, the device identified the interface as an attack source.


  1. Run the display auto-defend attack-source detail command to check the detected attack source and check whether it is an authorized user.
  2. If the interface is attacked and it connects to only one user, you do not need to take any actions because the attack has been blocked. Go to step 5.
  3. If the interface is connected to multiple users and some users initiate attacks, you can configure the blacklist.
  4. If only entries exist on the interface or entries cannot be determined, collect alarm, log, and configuration information, and contact technical support personnel.
  5. End.
