Displaying PXF Traffic Loads
The
show pxf cpu context
command provides the current and historical loads on the PXF.
Note
Enter the
show pxf cpu context
command twice in quick succession to obtain valid traffic load output.
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.
Router#
