Using NMDUMP for the SNA Links

SNA Transport Output Formats

For SNA Transport, NMDUMP formats tracing records and logging records. When NMDUMP displays the list of subsystems and IDs, and prompts you for the IDs you want to select, specify the ID for SNA Transport: 1. Then, proceed normally with NMDUMP. The format for each type of record is described below.

Tracing Records

Figure 5-1 “SNA Transport Trace Format Example ” shows a partial format of a tracing record for SNA Transport.

	NOTE: All numeric values in the SNA Transport trace are given in hexadecimal.

SDLC Link Output Formats

For the SDLC link, NMDUMP formats tracing records and logging records. When NMDUMP displays the list of subsystems and IDs, and prompts you for the IDs you want to select, specify the ID for SDLC Link: 27. Then, proceed normally with NMDUMP. The format of the tracing records is shown below.

X.25 Link Output Formats

For the X.25 link, NMDUMP formats tracing records. (Logging information is contained within the SNA Transport logging information.) When NMDUMP displays the list of subsystems and IDs, and prompts you for the IDs you want to select, specify the ID for X.25 Link: 38. Then, proceed normally with NMDUMP. The format of the tracing records is shown below.

Token Ring Link Output Formats

For the Token Ring link, NMDUMP formats tracing records and logging records. When NMDUMP displays the list of subsystems and IDs, and prompts you for the IDs you want to select, specify the ID for Token Ring Link: 61. Then, proceed normally with NMDUMP. The format of the tracing records is shown below.
