PXF Troubleshooting Information
The PXF has 16 processors, only one of which is in use at a time when there is a low traffic rate. Even
though only one of the processors is working, all of the PXF processors are slightly slowed. At higher
traffic rates many of the PXF processors are working at the same time, but there is no additional slow
down.
High Route Processor CPU Usage
High RP CPU usage may result from punting of packets from the PXF processors to the RP. Enter the
show
pxf accounting summary command to view the number and cause of punts.
