Using NMDUMP for the SNA Links
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.
Tracing Records
Figure 5-3 is a partial example of the format of a tracing record for the
SDLC link.
