SOC_1.3.6.1.4.1.2011.5.25.165.1.11.25 hwBaseNdVlanCarTrap

Trap Buffer Description

ND VLAN CAR became effective on an interface, which was probably due to an attack on the interface. (Protocol Type = [NdType], Logical Interface = [LogicalInterface], Physical Interface = [PhysicalInterface], Pe-Vlan = [PeVlan],Ce-Vlan = [CeVlan], Sample Rate = [SampleRate])

ND VLAN CAR took effect, indicating that an attack occurred on the interface.

Impact on the System

The system is attacked by ND packets, but the system automatically limits the attack traffic. Services are not affected.

Possible Causes

The rate of ND packets sent to the CPU exceeded the set threshold. The system was attacked by ND packets.
