Abstract
In one embodiment, the internal path traversed by packets between two user visible interface, selected by a user, is displayed. The path displayed includes internal interfaces traversed by the packets. First and second count values showing the packets traversing each displayed internal interface at the beginning and end of a selected time period are also displayed. A delta, being the difference between the first and second count values for each internal interface indicates the number of packets traversing the interface during the time period and can be analyzed to determine the identity of a packet processing hardware logic block where packets might be getting dropped.
