Displaying the Operational State of the Interfaces
Question How do I display the state of an interface (for example, up, down,
disabled)?
Answer
1. Access the OPCON prompt ( * ). (See “Accessing the OPCON
Command Line Interface” on page A-3)
2. Type talk 5 and press Enter to reach the + (monitoring) prompt. If
the + prompt does not appear, press Enter again.
3. Type configuration.
4. Press Ctrl-p to return to the OPCON (*) prompt.
Verifying IP Connectivity

Answer
1. Access the command line interface (the * prompt).
2. Type talk 5 and press Enter twice to reach the
+
prompt.
3. Type protocol and press Enter.
4. Type ip and press Enter. The prompt changes to

Managing Operational Code and Configuration Files
To help you manage operational software upgrades and configurations, the IBM
2212 has a software change management feature. This utility enables you to
determine which operational software file and configuration file are active while the
IBM 2212 is running. It also has a service recovery interface that enables you to
perform many of the same tasks.
Reconfiguring
You might find it difficult to detect problems caused by configuration errors. A
configuration error can initially appear to be a hardware problem because the 2212
will not start or data will not flow through a port. In addition, problems with
configuration may not result in an error initially; an error may occur only when
specific conditions are encountered or when heavy network traffic occurs.
If you cannot resolve a problem after making a few changes to your configuration
or after restoring the active configuration file, it is recommended that you generate
a new configuration. Too many changes to a configuration often compound the
problem, whereas you can usually generate and test a new configuration within a
few hours.
