sFlow now supports buffer drop and forward-drop streaming, enhancing its capability to capture packets dropped by the Traffic Management (TM) buffer when full. This feature allows streaming of mirrored copies of these packets using SPAN, ensuring effective traffic monitoring even during process restarts or network failovers. Additionally, it mirrors forward-drop packets to capture and analyze packets dropped at router ingress, aiding in understanding blocked traffic types, identifying potential security threats, and optimizing network performance.
