Figure 21 Scope of X.25 diagnostic utilities
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.
NOTE: You should be familiar with X.25 data formats in order to understand diagnostic output.
x25check and x25server
These commands are used together to test the connection between a source node and a destination
node, up to and including X.25 programmatic access level. x25check is a major tool for debugging
the X.25 subsystem and for checking the configuration for that subsystem. x25server is a
