Cisco CMTS Debugging Commands

To enable debugging of the Parallel eXpress Forwarding (PXF) subsystems on the active Performance

Routing Engine (PRE1) module on the Cisco uBR10012 router, use the debug pxf command in

privileged EXEC mode. To disable debugging output, use the no form of the command.

Command History

Usage Guidelines

The debug pxf command enables debugging of the different subsystems that are active on the PXF

processors that are on the PRE1 modules in the Cisco uBR10012 router.

Also, by default the PRE1 modules automatically reload the microcode on the PXF processors in case

of a crash or fault. The debug pxf microcode command disables this automatic reloading of the

microcode, to allow further debugging. When you have finished debugging the PXF processor, you then

must manually reload the microcode on the PXF processor using the

debug pxf dma

The following example shows how to enable debugging of the DMA engine on the PXF processor, as

well as typically debugging messages that appear for the packets sent and received by the ping
