Now you can check the service statistics for that TSP process.
The SCF command
stats service $tsp2.#l4
displays the following:
This screen shows that one TPDU was sent and two TPDUs were received. You can also
see in the last two lines that no transport connection was ever established.
From this information, you can narrow the problem down to the Transport Layer. The
Session Layer is waiting for the Transport Layer to establish a connection, but the
Transport Layer is unable to do so. The fact that TPDUs have been exchanged indicates
that the Network Layer must be intact. (Remember that no TPDUs can be exchanged
until the Network Layer has established a connection and has moved into the data
transfer phase.)
