IBM SY44-5902-05 manual Select the Work with communications traces option, Format and print trace

You can select how much data is traced in a frame of data. The value that is entered is the amount that is saved as part of the trace. The minimum value that is allowed for both the beginning and the end value is 36 bytes. Those 36-byte minimum values include the protocol header. The configuration object you are tracing determines the maximum value that is allowed.

Notes:

1.The BSC protocol ignores the beginning and ending byte values.

2.The SDLC, high-level data link control (HDLC), X.25, frame relay, Ethernet, distributed data interface (DDI), ATM, and token-ring protocols ignore the ending byte value.

3.The minimum value that is allowed for the beginning byte value for local area network (LAN) protocols (including frame relay protocols and ATM protocols) is 72 bytes.

When all required options are complete, press the Enter key. The Work with Communications Trace display appears.

If the communications object being traced is in varied off status when you start the trace, the trace remains in waiting status until you vary the communications object on. If the object is varied on, the trace will immediately go to the active state, and the system will begin to collect trace data.

The trace remains active until one of the following occurs:

vYou select the option to stop the trace on the Work with Communications Traces display.

vYou vary off the configuration object being traced.

vThe configuration object being traced has an error.

vThe trace buffer is full, and the option to stop on buffer full was selected.

Note: You can exit the communications trace function to do other work while the trace is active.

Traces are not automatically deleted when you exit a communications trace function. To return to the communications trace:

1.Select the Start a service tool option from the service tools (SST or DST) display.

2.Select the Work with communications traces option.

3.From the Work with Communications Traces display, you can check the status of the trace or select to stop the trace.

Format and print trace

You must select the Stop Trace option before you format or print the trace. The Format and print trace option allows you to select various formatting options and prepare the trace data for printing. The options vary for each protocol. The following is an example of the Format Trace Data display:
