Statistics for PM sessions are held in on-chip RAM that can be read at any time through the
32-bit general purpose microprocessor port.
Paced insertion of PM cells is provided.
PM block size generation and termination is per-session programmable ranging from 128 –
32768 cells.
Each of the 512 PM sessions can be configured to be a source, sink or non-intrusive
monitoring point of PM cells.
PM processes support the aggregation of F5 flows into F4 flows, and the termination of F4
flows into its constituent F5 flows.
2.3
Cell Counting
Counts maintained on a per-VC basis include total low or high priority user cells, OAM cells,
RM cells, and invalid cells, cells violating the traffic contract, and total AAL5 frames.
Aggregate counts are also provided when aggregating or terminating VPCs.
Counts maintained on a per-PHY basis include: number of CLP0 cells received, number of
CLP1 cells received, number of OAM cells received, number of RM cells received, number
of errored OAM cells, number of errored RM cells, number of cells with unassigned,
unprovisioned, or invalid VPI/VCI/PTI, the number of inserted OAM cells timed-out to avoid
head-of-line blocking, and the number of cells received with a non-zero GFC and/or with
EFCI indicated in their PTI fields.
The Per-VC Non-Compliant and Per-PHY Non-Compliant counts can be used to count total
frames, whether or not policing is enabled.
