Diagnostic Utilities

Before Using the Diagnostic Utilities

NOTE

Before Using the Diagnostic Utilities

Some of the diagnostic utilities request or display information about the X.25 interface card using one or more of the naming conventions described below. Keep these conventions in mind when using the diagnostic utilities:

•the name of the device file, uses the format x25_npx, where n represents the card instance number (0 to 15). For systems with multi-port cards only, the p is a mandatory place holder and x represents the port (interface) number (either 1 or 4).

•the programmatic access name (for example, interfacenpx)

•the X.25 interface name used by netstat uses the format

x25_npx, where n represents the card instance number (0 to 15). For systems with multi-port cards only, the p is a mandatory place holder and the x represents the port (interface) number (either 1 or 4).

The interrupt signal is often used to terminate diagnostic utilities. This chapter assumes you have designated the Break key as your interrupt character by setting the stty flags, brkint and -ignbrk. See the man page for stty for details.

You should be familiar with X.25 data formats in order to understand diagnostic output.
