Using NMDUMP for the SNA Links
Using NMDUMP for the SNA Links
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 shows a partial example of the format of a tracing record for
SNA Transport.
NOTE All numeric values in the SNA Transport trace are given in
hexadecimal.
