Configuring the Switch with the CLI-Based
Setup Program
This appendix provides a command-line interface (CLI)-based setup procedure for a standalone switch.
Before connecting the switch to a power source, review the safety warnings in Chapter 2, “Switch
Installation.”
For an unconfigured switch, you can access the CLI either through Express Setup or through the console
port. These sections describe each method:
• Accessing the CLI Through Express Setup, page D-1
• Accessing the CLI Through the Console Port, page D-2
Accessing the CLI Through Express Setup
Express Setup is supported on switches running Cisco IOS Release 12.1(14)EA1 or later. If you are
installing an unconfigured switch, see the Cisco IOS release label on the rear panel of the switch to
determine the software release.
Note For switches running releases earlier than Cisco IOS Release 12.1(14)EA1, go to the “Accessing the CLI
Through the Console Port” section on page D-2.
You can access the CLI on an unconfigured switch by placing the switch in Express Setup mode and then
by connecting a switch Ethernet port to the Ethernet port of your PC or workstation. To put the switch
into Express Setup mode, follow the steps described in the getting started guide for powering on the
switch and using Express Setup.
After the switch is in Express Setup mode, open a Telnet session to the switch by entering the IP address
10.0.0.1. Enter the setup user EXEC command. See these sections in this chapter to then configure the
switch by using the CLI:
• Entering the Initial Configuration Information, page D-4
• Completing the Setup Program, page D-5
After you have entered the configuration information for the switch, save it to Flash memory by using
the write memory privileged EXEC command.
