Configuring Remote Access

• A firmware diagnostics monitor with a command-line interface. You use the
AN/ANH/ARN monitor to configure the router’s boot configuration.
This manual describes how to configure the router’s boot configuration using the
Diagnostic Monitor and Technician Interface, and how to connect remote access
systems to a managed network using Site Manager.
Router Software
Before it can operate, the AN, ANH, or ARN hardware must boot a software
image. The software image is a group of executable files that operate the protocols
that the network requires. The AN/ANH software image is called an.exe. The
ARN software image is called arn.exe. The software image comprises the
following executable startup files:
•A krnl_an.exe file (for the AN/ANH) or krnl_arn.exe (for the ARN) that
contains the operating system kernel.
• Application files -- executable files needed to perform the functions specified
in the configuration file. All application files have .exe filename extensions.
(For example, the router needs an ipx.exe executable file to run IPX.)
• String files -- compressed ASCII files needed when you use the Technician
Interface to display the event log or management information base (MIB)
object names. Groups of string files remain in compressed format within the
an.exe or arn.exe file until needed.
To bridge and route traffic, the AN, ANH, or ARN also needs a configuration file
that is tailored to your network. A configuration file is a binary system file that
contains hardware and software configuration data. The default configuration file
is named config.
