Assigning the Switch IP Address and Default
Gateway
This chapter describes how to create the initial switch configuration (for example, assigning the IP
address and default gateway information) by using a variety of automatic and manual methods. It also
describes how to modify the switch startup configuration. Unless otherwise noted, the term switch refers
to a switch and to a switch stack.
Note For complete syntax and usage information for the commands used in this chapter, see the command

This chapter consists of these sections:
• Understanding the Boot Process, page 3-1
• Assigning Switch Information, page 3-2
• Checking and Saving the Running Configuration, page 3-11
• Modifying the Startup Configuration, page 3-12
• Scheduling a Reload of the Software Image, page 3-17
Note Information in this chapter about configuring IP addresses and DHCP is specific to IP Version 4 (IPv4).
If you plan to enable IP Version 6 (IPv6) forwarding on your switch, see Chapter 39, “Configuring IPv6
Unicast Routing” for information specific to IPv6 address format and configuration. To enable IPv6, the
stack or switch must be running the advanced IP services feature set.
Understanding the Boot Process
To start your switch, you need to follow the procedures in the hardware installation guide for installing
and powering on the switch and setting up the initial switch configuration (IP address, subnet mask,
default gateway, secret and Telnet passwords, and so forth).
