TSP Process
Record #117 shows the connection acceptance, indicating successful completion of the
session connection.
TSP Process
The TSP process provides reliable end-to-end data transfer. It acts as the provider for the
Session Layer, Presentation Layer, and ACSE (the TAPS process), and is the user of the
Network Layer (the NSP is either X25AM or TLAM or PAM. The TSP process has its
own trace capability.
Error codes, such as error 140, are returned when the TSP subdevice detects an error.
Common problems to look for are ER-TPDUs or RJ-TPDUs, and DR-TPDUs rejecting
CR-TPDUs.
SCF Commands
You can get an overall look at the transport service layer within a TSP process by using
the following command:
STATS SERVICE $TSP.#L4
The returned screen displays a count of the number of TPDUs sent and received, the
number of bytes of user data transferred, and the number of connect requests refused for
any reason. It also shows the number of transfer timeouts, if any, and any TPDU errors
that were detected.
The following command applies only to TSPs configured to use TLAM (on D-series
releases) or PAM (on G06 and above releases):
STATS SERVICE $TSP1.#L3
The returned screen displays the number of IPPDUs exchanged, the number of IPPDUs
discarded, and the reasons they were discarded.
Using the following command, you can get the service information for both #L3 and
#L4:
STATS SERVICE $TSP1.*
