Release Notes for the Catalyst 3750 Switch Cisco IOS Release 12.1(14)EA1

OL-4215-01

Installation Notes

You can assign IP information to your switch by using these methods:

• The Express Setup program (See the procedure that follows).

• The setup program (Refer to the Catalyst 3750 Switch Hardware Installation Guide.)

• The Dynamic Host Configuration Protocol (DHCP)-based autoconfiguration (Refer to the

Catalyst 3750 Switch Software Configuration Guide.)

• Manually assigning an IP address (Refer to the Catalyst 3750 Switch Software Configuration

Guide.)

Note If you are upgrading a switch that uses the 802.1X feature, you must re-enable 802.1X after upgrading

the software. For more information, see the “Cisco IOS Notes” section on page 20.

Using Express Setup to Configure a Switch

Express Setup is a browser-based program that you can use to set up and configure the switch. You assign

the IP information so that the switch can connect to local routers and the Internet. The IP address is also

required if you plan to further configure the switch.

You do not create a username with Express Setup. Express Setup provides the minimum configuration

to configure a switch. To create a username for the switch, use the Cluster Management Suite (CMS) or

the command-line interface (CLI).

Note To use Express Setup, you must have Cisco IOS Release 12.1(14)EA1 or later running on your switch.

This section provides a quick step-by-step setup procedure for a standalone switch and includes these

steps:

• Starting Express Setup, page 8

• Configuring the Switch Settings, page 10

• Clearing the Switch IP Address and Configuration, page 13

• Where to Go Next, page 13

Caution Do not start Express Setup when there are any devices connected to the switch or connect a switch that

is already in Express Setup mode to any device other than the PC or workstation that is being used to

configure it. The switch acts as a DHCP server during the Express Setup procedure, and only the PC or

workstation connected to the switch after Express Startup is started should receive a DHCP address from

the switch.

Before using Express Setup to configure a switch, refer to the switch hardware installation guide for this

information:

• Removing the switch and AC power cord from the shipping container

• Getting an Ethernet (Category 5) straight-through cable to connect the switch to your PC or

workstation

• Powering on the switch
