COMMON DEFINITIONS
Extensible Structured Tokens
ZS-FRAMES-SENT contains the total number of S-frames sent.
ZS-FRAMES-RECV contains the total number of S-frames received.
ZU-FRAMES-SENT contains the total number of U-frames sent.
ZU-FRAMES-RECV contains the total number of U-frames received.
The following fields of ZEXP-MAP-STATS-LINE-CSM (fields ZBCC-ERRS
through ZFRAMES-ERR) relate to the numbers of errors in received
frames. These error counts apply only to the link between the
I/O process and the CLIP (that is, to the CIU-to-LIU Bus, or
CLB).
ZBCC-ERRS contains the total number of BCC/VRC errors and FCS
errors detected in driver frames received by a bit-synchronous or
byte-synchronous controller.
ZALLOC-ERRS contains the total number of buffer-allocation
failures.
ZQUAL-ERRS contains the total number of line-quality errors.
ZFRAMES-TOTAL contains the total number of frames handled.
ZFRAMES-ERR contains the total number of received frames that had
errors. The count of error frames is incremented each time one
or more of the following errors occurs while receiving a frame:
• A BCC/VRC error or an FCS error on a frame received by a bit-
synchronous or byte-synchronous controller
• An overrun error due to unavailability of resources
• A one-byte frame (for LAPX protocol only)
The count is also incremented each time a level-2 timeout occurs
while level 2 is waiting for an acknowledgment of an information
frame.
The following fields of ZEXP-MAP-STATS-LINE-CSM (fields ZL2-I-
FRAMES-SENT through ZL2-SREJ-FRAMES-RECV) contain a more detailed
breakdown of the numbers of level-2 frames sent and received.
ZL2-I-FRAMES-SENT contains the total number of I-frames without
the poll bit set that have been sent.
ZL2-I-FRAMES-SENT-P contains the total number of I-frames with
the poll bit set that have been sent.
