JUNOS Enterprise Switching

Chapter 3. Initial Configuration and Maintenance

Now that we have introduced you to JUNOS, it is time to get started with initial switch configuration. This chapter walks through the configuration and hardware status checks typically performed when installing a brand-new EX switch. A new switch is set to a factory-default configuration, and the goal of this chapter is to teach you how to configure the switch with the most common settings needed to get the chassis up and running with network management and user accounts. The topics covered include:

• Factory-default configuration and EZSetup

• Initial configuration using the command-line interface (CLI)

• Secondary configuration using the CLI

• EX interfaces

• Chassis monitoring and network tools

JUNOS is a flexible operating system and there are several ways to skin the initial configuration cat, which is not to say that any animals were harmed during production of this material. We begin with a quick overview of the EZSetup Wizard, but the focus rapidly shifts to the CLI, where the real work can be quickly done.

This chapter walks you through the addition of a new Juniper Networks EX4200 switch, in this case named Tequila, using both EZSetup and the CLI, and demonstrates chassis status monitoring and validation of initial configuration services and operation. The new switch is being integrated into a legacy switched network that comprises two Cisco Catalyst 3550 switches named Whiskey and Gin. Figure 3-1 shows the planned topology expansion.
