Configuration and Troubleshooting Commands

Utility with programmatic interface that allows users to get additional X.25 statistics.

x25ping

Checks if a remote host can be reached via the X.25 interface. See your man pages.

ping

Tests connectivity to a remote host up to the Internet

Protocol (IP) level (level 3). See your man pages.

route

Used to add a host or network to the network routing table. See your man pages.

proxy

The Probe proxy table is the NS equivalent of the Internet/Berkeley Services /etc/hosts file. See your man pages.

netstat

Displays network statistics and information about network connections. See your man pages.

x25trace

Protocol level tracing facility. See your man pages.

x25upload

Dumps the interface card memory into a file. See your man pages.

nettl

Creates a user-defined log file containing frame and packet trace information from X.25 packet and LAP-B levels. See your man pages for x25trace and the examples in Chapter 7, “Tracing and Logging Utilities.”

netfmt

Formats trace information contained in the user-defined log file that was generated with the nettl command. See your man pages for x25trace and the examples in Chapter 7, “Tracing and Logging Utilities.”
