Description

SECE/4/STRACKPORT:OID [oid] An attack occurred.(Interface=[OCTET], InnerVlan=[INTEGER], OuterVlan=[INTEGER], EndTime=[OCTET], TotalPackets=[INTEGER])

The system detected an attack on an interface.

Attribute

Alarm ID Alarm Severity Alarm Type
1.3.6.1.4.1.2011.5.25.165.2.2.1.2 Warning securityServiceOrMechanismViolation(10)

Parameters

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

InnerVlan

Indicates the inner VLAN ID of 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 interface 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 on an interface and check whether the interface is normal according to the packet increase rate in entries.
  2. If an attack is initiated by a user and the user is the only one connected to the interface, shut down the interface and check whether the interface is normal.
  3. If the interface is connected to multiple users and some users initiate attacks, configure attack source tracing and set the action taken on attack packets to deny, or configure a traffic policy to discard attack packets.
  4. If only entries exist on the interface or entries cannot be determined, collect alarm, log, and configuration information, and contact technical support personnel.
