Considerations
TO file-spec
file-spec specifies the file to which tracing is to be initiated. The file may have
been previously created by you as an unstructured file with file code 0.
WRAP
causes the trace segment data to wrap instead of stopping the trace when it
reaches the end of file. The default is FALSE.
STOP
discontinues the trace currently in progress.
Considerations
•
Unless otherwise instructed by your HP representative, select all of the trace
record types. This is the default.
•
The PROCESS name of the network control process is always $NCP.
•
The keyword L0 applies to both LINE and PATH objects. When L0 is used with
LINE, all frames sent and received on that line are traced. When L0 is used with
PATH, all frames for which this system is either the source or the destination are
traced in the PATH trace.
•
The keyword ALL selects all mask bits.
•
Selecting a keyword that does not apply to the object type specified has no effect.
•
All keywords apply when the object is a single-line path. For keyword L0, it is
treated as a LINE object.
•
You can trace several objects with a single TRACE command by specifying
multiple objects using parentheses as follows:
PATH ( path-name , path-name [ , path-name ] ... )
LINE ( line-name , line-name [ , line-name ] ... )
Examples
The following SCF command initiates a trace of communications line interface
processor (CLIP) inbound and outbound frames for $LINE1. One-thousand trace
records are captured. The trace records are written to the file X1:
-> TRACE LINE $LINE1, TO X1,SELECT(CLIPDI,CLIPDO), COUNT 1000
The following SCF command terminates an existing trace of path $PATH1:
-> TRACE PATH $PATH1, STOP
The following SCF command initiates a trace of the network control process:
-> TRACE PROCESS $NCP, TO NCPTRC, SELECT ALL, RECSIZE 500, WRAP
