Troubleshooting Example
Pressing the N key continues the search and displays the following:
This screen shows that record #147 of the trace is the connect SPDU as it was received
by the TAPS process. Notice the value of the called SSEL field (this is important later).
Pressing the N key continues the search and displays the following:
This screen shows that record #169 of the trace is the response from the TAPS provider.
The connect request is refused with an RF-SPDU. The reason code describes the
problem: %H81 means that the SSEL value received in the CN-SPDU was unknown.
(Reason codes are described in the Session Layer standards.) In other words, there was
no local entity configured with that SSEL ready to accept the connect request.
Looking back at the ATTACH primitive in record #47, you can see that it was enabled
against SSEL 5555 01. But the remote entity in record #147 is requesting a connection
with SSEL 5555 03. Record #169 shows the TAPS process responding correctly by
sending an RF-SPDU, with the reason code %H81. The application never received a
notification because the ATTACH request was posted with an indefinite time limit, and
no connect was received to match the local SSEL field.
