UTILIZATION OF VISIBILITY FEATURE TO OBTAIN AND INCORPORATE DROP REASONS INTO MIRROR ON DROP REPORTS

Abstract: systems and methods in which a network switch detects a dropped packet and automatically generates a report with information on the dropped packet. additionally, a visibility packet that includes the dropped packet and one or more additional headers is generated. the headers are used to route the visibility packet to the pipeline of the network switch that originally processed the dropped packet. the headers also include a visibility indicator that causes the pipeline to store visibility data. as the visibility packet is processed by the pipeline, information (visibility data) generated during the processing of the packet is stored in a visibility memory. the visibility data is retrieved from the visibility memory and added to the generated report prior to transmitting the report to an external collector for analysis of the packet drop.
