Starting the ARN
This chapter describes how to start the Passport ARN router, as follows:
Understanding the Startup Process
To operate, the ARN requires two files: a software image and a configuration file.
Each time you start the ARN, it completes a process to load these files.
•
The
software image
contains a group of executable files that support the
protocols that the network requires. The ARN uses the software image called
arn.exe
. The process of obtaining and using this image is called
booting
.
•
To bridge and route traffic, the ARN also needs a configuration file that is
tailored to the network. A
configuration file
is a binary system file that
contains hardware and software configuration data. The default configuration
file is named
config
.
Nortel Networks ships the executable and default configuration files on a
PCMCIA flash card, but the ARN can also obtain them over the network. Getting
a file over the network is called network booting, or
netbooting
. Getting a file
from the router file system, stored in flash memory, is
local booting
.
