Line trace detail reports

z/OS Communications Server: ACF/TAP Trace Analysis Handbook
GC27-3645-00

The selection parameter is LDPRT.

This topic contains line trace detail reports. See the following figures:

Table 1 describes the column headers and the trace data contained in this report type. To locate this information about the sample reports, reference the numbers (n) listed in this table to the corresponding numbers (n) shown in the sample reports.

Table 1. Line trace detail report
Reference number (n) Report column headers and the trace data
1 The page heading contains the report name, report parameter, and the date the report was printed or displayed.
2
RECORD NUMBER
The ACF/TAP-assigned sequence number of the physical line trace record that was being processed when this line was printed or displayed.
3
TYPE
Specifies the following trace data types of the record:
CSP
NCP line trace data
ENET
ESS line trace data
ESIT
ESS SIT data
FRLY
Frame-relay line trace data
FSIT
Frame-relay SIT data
NTRI
Line trace data from NTRI
SIT
Scanner interface trace data
X.25
X.25 trace data
4
LINE ADDR
The element address of the line that was being traced.
5
ELEMENT NUMBER
The sequence number of an NCP line trace element from the input trace file.
6
ID-COMMAND
The instruction (ID) or command that was being processed when the trace record was written. The COMMAND part of this field--only entered on STAT entries.
The ID information includes the following:
CHKPT
Checkpoint entry.
IOH
Input/output halfword data (see Note).
PARM
The parameter part of the PSA with no command entry.
RDATA
Receive data.
STAT
The status part of the PSA with a command entry.
XDATA
Transmit data.
Note: IOH consists of the tag address (TA) and the tag data (TD) fields of the IOH instruction sent to the scanner (for type of SIT).
The information for both ID and command includes the following:
COUNT
Get counter entry from the ESS line trace data.
NTRI IOH
NTRI I/O halfword.
NTRI LINE
Receive or transmit data from NTRI.
RCV CTRLWORD
Receive control word from the SIT data.
RDATA FRSE
Receive data from frame-relay switching equipment.
RDATA FRTE
Receive data from frame-relay terminal equipment.
RDATA LMI
Receive data from local management interface connection.
T-R IP ARP
Receive or transmit an ARP frame over an NTRI connection.
T-R IP LINE
Receive or transmit IP data over an NTRI connection.
XDATA FRSE
Transmit data from frame-relay switching equipment.
XDATA FRTE
Transmit data from frame-relay terminal equipment.
XDATA LMI
Transmit data from local management interface connection.
6 (Continued)
XMIT CTRLWORD
Transmit control word from the SIT data.
For a list of valid commands, see NCP and EP Reference Summary and Data Areas, LY43-0030.
7
ENTRY TYPE/SCANNER STATE
  • For STAT entries, this is the mode the scanner was in when the trace record data was recorded.
  • For NTRI line entries, this is the type of data.
8
TIME
The relative elapsed time (in hexadecimal) between the entries to the nearest 100 milliseconds. The time is measured from trace activation to the level 2 interrupt that is represented by each entry.
For SIT and NTRI, this field is blank.
9
TCC
The transmission correlation counter used to correlate SIT and NCP line trace entries for the same event.
For NTRI, this field is blank.
10
HEX
The hexadecimal trace entry from the PSA control block.
11
TRANSLATION
This is the EBCDIC equivalent of the hexadecimal trace data.

For more information about gathering data for these traces, see Gathering host-collected trace data.
