Optivity®/Internetwork
, a comprehensive, SNMP-based network
management application for administering and troubleshooting large,
complex networks. The Optivity/Internetwork package includes Site
Manager, PathMan™, and RouterMan™ software.
Router Software
Before it can operate, the AN and ANH hardware must boot a
software image. The
software image is a group of executable files that operate the protocols the
network requires. The AN/ANH software image, called an.exe, comprises the
following executable startup files:
•A krnl_an.exe file 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 file until needed.
To bridge and route traffic, the AN/ANH 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.
Boot Configuration Options
This section summarizes your options for getting the AN/ANH software image
file and configuration files.
An AN/ANH boots using one of four configured startup options. The differences
among the four AN/ANH startup options are based on whether the router retrieves
boot and configuration files over the network or from local memory.
Getting a software image or configuration file over the network is called
Netbooting. Getting a file from the file system stored in local Flash memory is
called Local booting.
