SmartSwitch Router User Reference Manual 3
Chapter 1
Introduction
This chapter provides information that you need to know before configuring the
SmartSwitch Router (SSR). If you have not yet installed the SSR, use the instructions in the
SmartSwitch Router Getting Started Guide to install the chassis and perform basic setup
tasks, then return to this manual for more detailed configuration information.
Configuration Files
The SmartSwitch Router Getting Started Guide introduced the following configuration files
used by the SSR:
• Startup – The configuration file that the SSR uses to configure itself when the system
is powered on. The Startup configuration remains even when the system is rebooted.
• Active – The commands from the Startup configuration file and any configuration
commands that you have made active from the scratchpad. The active configuration
remains in effect until you power down or reboot the system.
• Scratchpad – The configuration commands you have entered during a CLI session.
These commands are temporary and do not become active until you explicitly make
them part of the active configuration.
Note:
Because some commands depend on other commands for successful execution,
the SSR scratchpad simplifies system configuration by allowing you to enter
configuration commands in any order, even when dependencies exist. When you
activate the commands in the scratchpad, the SSR sorts out the dependencies and
executes the command in the proper sequence.
Entering commands and saving configuration files are discussed in more detail in the
following section.
