Alarm Information


Handling Process

The LPUB of the NE40E or NE80E of V300R002 has a special way to handle mirroring and traffic. Only a flag bit is reserved for mirroring or traffic sampling. When sampling is adopted, mirroring is unavailable. When mirroring is adopted, sampling is unavailable. The two functions are mutually exclusive. In later versions, the mirroring function is disabled and controlled through PAF. By default, PAF is disabled. If the mirroring function is needed, you must replace PAF or upgrade V300R003. In V300R001, the mirroring function can be configured. However, after you enable the mirroring function, the sampling function will be unavailable.
