Trace data processed by ACF/TAP
Table 1 lists the various trace types and the data that can be created using the trace facilities described in Trace facilities.
After the trace data has been created, the applicable output reports can be produced. For information about output report parameters and the output report contents, see Output report parameters.
| Trace type | Trace data description |
|---|---|
| BUFFER | VTAM® buffer trace records the contents of message buffers when data is sent by an application and when data is received from the network. |
| CSP | NCP line trace records the activity on a designated line attached to the communications controller. |
| CSS adapter | Gathers information from the 3746 Model 900 hardware. |
| CSS line | Records the data exchanged between NCP and the 3746 Model 900. |
| ENET | Ethernet subsystem line and scanner traces record information flowing between NCP and the Ethernet subsystem adapter on a designated line. |
| FRLY | Frame-relay line and scanner traces record the data flow on a designated frame-relay line. |
| GPT | NCP generalized PIU trace records the flow of PIUs exchanged between the NCP and its attached resources. |
| NETCTLR | Control unit trace for IBM® 3710 Network Controller traces SDLC, BSC, and S/S data link control frames sent or received by the controller. |
| NRF | Network Routing Facility records information about PIUs flowing in and out of NRF and the processing taking place on those PIUs. |
| NTO | Network Terminal Option FID0 maps the PIUs that flow between NTO and the NCP BSC/SS processor component on behalf of a specific NTO line. |
| NTO INT | Network Terminal Option internal trace records the processing of all control points as PIUs enter and leave NTO. |
| NTRI | NCP Token-Ring interconnection records the data
flow on a designated line in the token ring. Input/output halfword (IOH) trace records that are dedicated to a particular token-ring interface coupler (TIC) and the token-ring multiplexer that controls the TIC. |
| SIT | Scanner interface trace records the operating parameters of the line whenever the IBM 3720, 3725 or 3745 sends or receives data. Records outbound data after NCP processes it and inbound data before it is passed to NCP. |
| TG | NCP transmission group PIU trace records the activity on all lines contained in a transmission group as if it were a single line. |
| TIC | Token-ring interface coupler internal trace gathers information about the internal processes of the TIC and reports it to the host. |
| VIT | VTAM internal trace shows the sequence of internal events such as scheduling of processes, storage management and the flow of internal PIUs between VTAM components. |
| X.25 | NCP Packet Switching Interface (NPSI) traces (NPSI V2 and later) assist with NPSI/NCP communications problem determination specifies the physical circuit trace allows you to record the activity of a specific physical circuit that works with a communications scanner processor. |
| XI | X.25 SNA Interconnection trace records the activity on a physical circuit working with a communications scanner processor. |
