Field Description
FP context statistics
feed_back Packets requiring additional passes through the pipeline. This
counter is incremented once for each additional pass.
new_work New packets input to the PXF pipeline. This counter
represents a snapshot of the amount of incoming traffic being
processed by the processor.
null_context An indication of unused forwarding bandwidth (idle time).
This counter is incremented for every context during which the
PXF pipeline is not processing traffic. This counter represents
the processor’s potential to handle additional traffic. As the
processor becomes more busy, the value for null decreases until
it becomes zero, at which point the processor has reached its
maximum usage.
FP average context/sec
feed_back Displays the rate, in terms of the number of contexts per
second (cps) for the feed_back counter for the last 1-minute,
5-minute, and 60-minute time periods.
new_work Displays the rate, in terms of the number of contexts per
second (cps) for the new_work counter for the last 1-minute,
5-minute, and 60-minute time periods.
null_context Displays the rate, in terms of the number of contexts per
second (cps) for the null_counter for the last 1-minute,
5-minute, and 60-minute time periods.
FP context utilization
Actual Displays the actual percentage of processor usage per second,
compared to the theoretical maximum, for the last 1-minute,
5-minute, and 60-minute time periods.
Theoretical Displays the percentage of processor usage compared to the
ideal theoretical capacities for the last 1-minute, 5-minute,
and 60-minute time periods. The theoretical maximum for the
PXF processors is 3,125,000 contexts per second (cps).
Maximum Displays the actual maximum percentage of processor usage
that has occurred for the last 1-minute, 5-minute, and
60-minute time periods.
Command Description
