Description

SECE/4/STRACKUSER: OID=[OID] Attack occurred.(Interface=[STRING], SourceMAC=[STRING], CVLAN=[ULONG], PVLAN=[ULONG], EndTime=[STRING], TotalPackets=[ULONG])

The system detects an attack.

Attribute

Alarm ID	Alarm Severity	Alarm Type
303046936	Warning	securityServiceOrMechanismViolation

Parameters

Name	Meaning
OID	Indicates the MIB object ID of the alarm.
Interface	Indicates the access interface of the attacker.
SourceMAC	Indicates the Source MAC address of packets sent from the attacker.
BCVLAN	Indicates the maximum rate of broadcast packets.
PVLAN	Indicates the inner 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 rate of packets with the specified MAC address and VLAN ID sent to the CPU exceeds the alarm threshold.

Procedure

If the user initiates the attack, you can set the action taken on attack packets to deny, or configure a traffic policy to discard attack packets.
If the fault cause is unknown, collect device configurations, alarms, and logs, and then contact technical support personnel.
End.
