1.3.6.1.4.1.2011.5.25.165.2.2.1.1 Warning securityServiceOrMechanismViolation(10)

Parameters

Name Meaning
OID Indicates the ID of the MIB object.
Interface Indicates the access interface of the attacker.
SourceMAC Indicates the source MAC address of packets sent from the attacker.

InnerVlan

Indicates the inner VLAN ID of packets sent from the attacker.

OuterVlan

Indicates the outer VLAN ID of packets sent from the attacker.
EndTime Indicates the end time of the attack.
TotalPackets Indicates the number of packets received from the attacker.

Impact on the System

The CPU is busy processing attack packets. As a result, normal service packets cannot be processed in time or even discarded.

Possible Causes

The number of packets with the specified MAC address and VLAN ID sent to the CPU exceeded the alarm threshold.

Procedure

  1. Run the display auto-defend attack-source detail command to check the possible attack source and check whether the system is normal according to the protocol type and packet increase rate.
  2. If the user initiates the attack, add the user to the blacklist in the attack defense policy view to disable the user from sending packets to the CPU.
  3. If the fault cause is unknown, collect alarm, log, and configuration information, and contact technical support personnel.
