Chapter 4: Using the Command Line Interface

4 Using the Command Line Interface
All configurable EL-500 parameters can be accessed with a Command Line Interface (CLI).
The CLI allows you to:
• Modify and verify all configuration parameters
• Save and restore device configurations
• Reboot the device
• Upgrade the firmware
4.1 Accessing the CLI
The EL-500’s command-line interface (CLI) is accessible through its network interfaces using
an SSH client. Any of the network interfaces can be used to establish the SSH connection to
the EL-500. However, connecting through the Ethernet port is required for devices that have
not previously been configured.
Windows XP does not include an SSH client application. You will need to
install a 3
rd
-party client such as SecureCRT from Van Dyke software
(http://www.vandyke.com/products/securecrt) or the free PuTTY SSH client
(http://www.putty.nl/) to connect to an EL-500 using SSH.
When you log in to the EL-500, the CLI will present a command prompt. The shell timeout is
displayed above the login prompt. The CLI will automatically log out a user if a session is
inactive for longer than the timeout period. Section 9.9 describes how to change the timeout
period.
Shell timeout: 3 minutes.
