BPID
is the backup process ID.
Resettime
is the last timestamp that the statistics counters were reinitialized.
Sampletime
is the last timestamp that the statistics were collected.
LEVEL 2
shows the counts of the Layer 2 frames sent and received by this input-output
process (IOP) because statistics were last reset using the STATS RESET
command or because the line-handler process was started. The headings see the
Expand frame types, which are based on High-Level Data-Link Control (HDLC)
protocol definitions.
I-Frames
are information frames. This number is the total of the Information Frames
(I-FRM) and Information Frame with Poll Bit (I-FRM(P)) frame counts in the
LEVEL 2 DETAIL set of statistics in this display.
S-Frames
are supervisory frames. This number is the total of the Receive Ready (RR),
Receive Not Ready (RNR), Reject (REJ), and Selective Reject (SREJ) frames
transmitted because the last time the statistics were reset. SREJ frames apply
only to satellite-connect lines.
U-Frames
are unnumbered (nonsequenced) frames. This number is the total of the Set
Asynchronous Balanced Mode (SABM), Disconnect (DISC), and Unnumbered
Acknowledgment (UA) frame counts in the LEVEL 2 DETAIL set of statistics
in this display. The Disconnect Mode (DM) and Command Reject (CMDR)
frame counts are not included in the U-frames count because the last time the
statistics were reset.
LEVEL 2 DETAIL
is the number of Expand frames sent and received through this input-output
process (IOP), shown by frame type. If your system receives a large number of
SABM
, DISC, RR, or I-FRM(P) frames relative to the total number of information
frames (I-Frames), your system might have a noisy line. For more information on
troubleshooting Layer 2 problems, see Section
20, Troubleshooting.
