Nortel Secure Router 8000 Series
Configuration Guide - Basic Configuration
7.1 Introduction
This section provides an overview of configuration file concepts.
7.1.1 Configuration file
Configuration files are configuration items uploaded at the current startup or next startup of
the router.
The configuration file is a text file in the following format:
• It is saved in the command format.
• To save space, default parameters are not saved. For the default values of the
configuration parameters, see
Nortel Secure Router 8000 SeriesSeries Routers-
Commands Reference (NN46240-500).
• Commands are organized by command view. All commands of the same command view
are grouped into a section. Command sections are separated by one or several blank lines
or comment lines (beginning with #).
• The sequence of command sections is as follows: global configuration, physical interface
configuration, logical interface configuration, routing protocol configuration, and so on.
OQ NOTE
• The system can run commands with a maximum length of 255 characters, including commands in
the incomplete form.
• If a command is entered in the incomplete form, the command is saved in the complete form.
Therefore, the command length in the configuration file may exceed 255 characters. When the
system is restarted, these commands cannot be restored.
7.1.2 Configuration files and current configurations
Initial configuration: When the router is powered on, it retrieves the configuration files
from the default save path to initiate itself. If no configuration file exists in the default
save path, the router uses the default parameters.
Current configuration: Indicates the configuration of the currently running router.
You can modify the current router configuration through the command line interface
(CLI). When you use the save command to save the current configuration to the
configuration file of the default storage devices, the current configuration becomes the
initial configuration the next time the router is powered on.
7.2 Displaying the configuration of the router
After configuration, run the display command in any view to view the running information in
the configuration file.
