PPID
is the primary process ID.
BPID
is the backup process ID.

LEVEL 2
shows the counts of the Layer 2 frames sent and received by this input-output
process (IOP) since statistics were last reset using the STATS RESET command
or since the line-handler process was started. The headings refer to 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 since 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 since the last time the
statistics were reset.
