Assigning the Switch IP Address and Default
Gateway
Note This chapter describes how to create the initial switch configuration (for example, assigning the IP
address and default gateway information) for the Catalyst switch by using a variety of automatic and
manual methods. It also describes how to modify the switch startup configuration. For complete syntax
and usage information for the commands used in this chapter, see the command reference for this release
and the Cisco IOS IP Command Reference, Volume 1 of 3: Addressing and Services from Cisco.com

Understanding the Boot Process
To start your switch, you need to follow the procedures in the Getting Started Guide or the hardware
installation guide for installing and powering on the switch and for setting up the initial switch
configuration (IP address, subnet mask, default gateway, secret and Telnet passwords, and so forth).
The normal boot process involves the operation of the boot loader software, which performs these
activities:
• Performs low-level CPU initialization. It initializes the CPU registers, which control where physical
memory is mapped, its quantity, its speed, and so forth.
• Performs power-on self-test (POST) for the CPU subsystem. It tests the CPU DRAM and the portion
of the flash device that makes up the flash file system.
• Loads a default operating system software image into memory and boots up the switch.
The boot loader provides access to the flash file system before the operating system is loaded. Normally,
the boot loader is used only to load, uncompress, and launch the operating system. After the boot loader
gives the operating system control of the CPU, the boot loader is not active until the next system reset
or power-on.
