This chapter describes how to configure the Catalyst 4840G processor so it can be accessed by other devices. For further information about the commands used in this chapter, see Appendix A, “Command Reference.”

This chapter includes the following sections:

Before Starting Up the Catalyst 4840G, page 3-1

Configuring the Management Port, page 3-3

Displaying the Operating Configuration, page 3-4

Enabling Fast Ethernet Client, page 3-4

Configuring a Host Name, page 3-5

Using Flash PC Cards, page 3-5

Note You are at Step 2 in the suggested procedure for configuring your Catalyst 4840G switch. See the“Switch Configuration Steps” section on page 2-1.

Before Starting Up the Catalyst 4840G

Before starting up the Catalyst 4840G switch, you should verify the following:

The cables are connected to the switch.

A console terminal is connected to the switch.

For instructions, refer to the Catalyst 4840G Chassis Installation Guide.

When you start up the switch, the CLI prompts you whether to enter the initial configuration dialog. Answer no to this prompt:

Would you like to enter the initial dialog? [yes]: no

You see the following user EXEC prompt:

Chapter 3 Configuring the Catalyst 4840G Processor

Before Starting Up the Catalyst 4840G

Using the Console Port or a Management Port

You can configure the Catalyst 4840G switch from a direct console connection to the console port or remotely through its management port.

If you are using a direct console connection, configure your terminal emulation program for 9600 baud, 8 data bits, no parity, and 1 stop bit.

If you are using an Ethernet interface as a management port interface, you must assign an IP address to the interface.

For interface configuration instructions, see the “Configuring the Management Port” section on page 3-3.

For further details on configuring ports and lines for management access, refer to the Cisco IOS

Configuration Fundamentals Configuration Guide.

Connecting a Modem

You can connect a modem to the console port on the Catalyst 4840G SLB switch. The following settings on the modem are required:

Enable auto answer mode

Suppress result codes

You can configure your modem by setting the DIP switches on the modem or by connecting the modem to terminal equipment. Refer to the user manual provided with your modem for the correct configuration information.

Note Because there are no hardware flow control signals available on the console port, the console port terminal characteristics should match the modem settings.

For further details on configuring ports and modems for management access, refer to the Cisco IOS

Configuration Fundamentals Configuration Guide and Dial Solutions Configuration Guide.

Using Passwords

You can configure both an enable password and an enable secret password. For maximum security, the enable password should be different from the enable secret password.

The enable password

The enable password is a nonencrypted password. It can contain any number of uppercase and lowercase alphanumeric characters. Give the enable password only to users permitted to make configuration changes to the SLB switch.

The enable secret password

The enable secret password is a secure, encrypted password. On systems running Cisco IOS software, you must type in the enable secret password before you can access global configuration mode. You must type in the enable secret password to access boot ROM software.

An enable secret password can contain from 1 to 25 uppercase and lowercase alphanumeric characters. The first character cannot be a number. Spaces are valid password characters. Leading spaces are ignored; trailing spaces are recognized.
