Troubleshooting Example
After recording the problem, be sure to stop the trace. The following SCF command
stops the trace:
trace process $tsp2, stop
Step 5: Analyze the Trace Using PTrace
The SCF command
ptrace from tr1
starts the PTrace trace formatter on the trace in TR1 and displays the following:
You should next set up the select mask and the filters for the trace. Since you already
know that the incoming connect TPDU was refused within TSP, you only need to focus
on the Layer 4 activity. Use the following PTrace commands to select all the appropriate
trace records:
select l4; filter l4sm; filter l4services
record all
The first trace record found is displayed as follows:
Record #30 indicates that the T-CONNECT attach has enabled the Transport Layer to
accept an incoming CR-TPDU.
Records #32 and #38 indicate that the state machine has enabled the Network Layer to
establish a connection.
Trace of: \MARS.$TSP2, Type (55,4).
