Troubleshooting Example
plus the subdevice port number) is 408333111102. The length of the facility field is 03
bytes. The facility field is 430202; this is the negotiated window size.
Record #60 shows that a clear packet was received with reason code 81, in response to
the call request packet. This reason code means that no subdevice on the remote side
was able to accept the connection.
Record #68 shows that X25AM correctly responded to the clear packet with a clear
confirm packet.
Step 6: Correct the Problem
Now that you know what the problem is, you need to correct it. Since you know that the
remote DTE can be reached by the address 408333222202, you need to alter the
X25DESTADDR by using the following SCF commands:
stop su $tsp1.#z000022
alter su $tsp1.#z000022, x25destaddr "408333222202"
You might also want to use one of the following SCF commands to verify the new
remote DTE address:
INFO SU $TSP1.#Z000022
INFO LINE $X25, DETAIL
The X25 process should now accept the connect request; you might take another trace to
confirm this. First, stop the application and then start the trace by using the SCF
command:
trace line $x251,to trx
While the trace is running, rerun the application. Stop the trace using the following SCF
command:
trace line $x251,stop
Use PTrace to analyze the trace. This time you need to look only at Layer 3. The SCF
command
