show pxf cpu
Context
The following example shows a typical display for the
context
option, which displays performance
statistics for the PXF processors over the past 1-minute, 5-minute, and 60-minute periods:

Note
The
show pxf cpu context
command displays more useful information on the processor’s performance
than the
show processor cpu command
that is used on other platforms.
This display shows statistics that are based on three counters on the PXF processors:
•
feed_back—Incremented each time the processor requires another processor cycle to process a
packet. Each PXF processor contains 8 columns that perform different packet header processing
tasks, such as ACL processing or QoS processing. A typical IP packet passes through all 8 columns
Parent
Parent of this prefix’s leaf or node entry in the adjacency table.
FP CEF/MFIB/TFIB XCM Type usage—The following fields display the memory usage of the shadow forwarding
information base (FIB).
Type
Level number of this particular memory block.
Name
Identifier for this particular memory block.
Total
Total number of nodes available on each level and changes to other data
structures.
Alloc
Number of nodes currently allocated.
Start, End
Starting and ending addresses for the memory block.
Error
Number of errors discovered in the memory block.
