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.
