Chapter 10 Configuration Tasks and Troubleshooting Information
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.
