Abstract
A methodology is described for providing a dedicated interface-level oversubscription diagnostics queue that would store header data and timestamps for ingress frames which would otherwise be dropped due to the input FIFO queue being full. When the microburst is over, the data may be transmitted to the main CPU to analyze the cause of oversubscription as well as affected traffic.
