The NMS utility NMDUMP can be used to format tracing and logging records for the SNA links. Described below are the tracing and logging formats produced for the SNA links by NMDUMP. Note that NMDUMP is described in more detail in Using the Node Management Services Utilities. If you are not familiar with NMDUMP, you should read that manual before running NMDUMP.

As stated earlier in this chapter, link trace logging information is written to the system log file, which your Hewlett-Packard support contact formats by using the DUI. So, no description of that file's format is given below.

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.

As stated earlier in this chapter, X.25 link logging information is contained within the SNA Transport logging information.

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.
