Start the SME buffer trace with the MODIFY TRACE command. For more information about the MODIFY TRACE command, see z/OS Communications Server: SNA Operation.

Make sure that the GTF with the TRACE=USR or TRACE=USRP option is active before starting this trace. See Starting the generalized trace facility (GTF). To format and print the data recorded by the GTF, use IPCS and set USR(FF1) on the GTFTRACE option.

For more information on printing trace output, see Formatting and printing trace records.
