The following example displays PXF L2TP packet statistics.
Note For L2TP Access Concentrator (LAC) operation, all statistics are applicable. For L2TP Network Server
(LNS) operation, only the PPP Control Packets, PPP Data Packets, and PPP Station Packets statistics are
meaningful.

dbg_frag_drop Count of invalid multilink PPP (MLP) fragment handles.
dbg_bndl_sem Count of semaphone collision (used for MLP).
context_inhibit Number of times multilink transmit fragment processing was
inhibited due to a lack of DMA resources.
bfifo_enq_fail Count of bundle FIFO (BFIFO) enqueue failures.
Column 7 Rescheduling State Counters by Rows:
High Next Time Current next send time for the high priority wheel.
Low Next Time Current next send time for the low priority wheel.
High Wheel Slot Current high priority slot number.
Low Wheel Slot Current low priority slot number.
DEQ_WHEEL Count of successful dequeues from the timing wheel.
DQ-lock Fails Count of timing wheel dequeue failures (both queue empty
and race conditions).
TW ENG Fails Timing wheel enqueue failures.
Q_SCHED Count of queues scheduled/rescheduled onto the timing
wheel.
FAST_SCHED Count of queues fast scheduled/rescheduled onto the timing
wheel.
Q_DEACT Count of queue deactivations.
Q_ACTIVATE Count of queue activations (activate state).
Q_CHANGE Count of queue changes; for example, Route Processor (RP)
inspired rates changes.
