Displaying PXF Traffic Loads
The show pxf cpu context command provides the current and historical loads on the PXF. The following
example shows how busy the PXF forwarding process (FP) is with the current traffic load. The FP
context statistics section displays the number of contexts of each type that have entered the PXF engine
since it was last reloaded. If counters are idle, the PXF pipeline is hung.

Displaying Feedback Counts
The show pxf cpu feedback command provides the total number of feedbacks through the PXF by all
packets.
