DES-3326SR Layer 3 Fast Ethernet Switch CLI Reference Manual

INTRODUCTION

The switch can be managed through the switch’s serial port, Telnet, or the Web-based management agent. The Command Line Interface (CLI) can be used to configure and manage the switch via the serial port or Telnet interfaces.

This manual provides a reference for all of the commands contained in the CLI. Configuration and management of the switch via the Web-based management agent is discussed in the User’s Guide.

Accessing the Switch via the Serial Port

The switch’s serial port’s default settings are as follows:

• 9600 baud

• no parity

• 8 data bits

• 1 stop bit

A computer running a terminal emulation program capable of emulating a VT-100/ANSI terminal and a serial port configured as above is then connected to the switch’s serial port via an RS-232 DB-9 cable.

You will initially encounter a blank screen; hit Enter twice and the following screen will appear:

Introduction 9

DES-3326SR Layer 3 Fast Ethernet Switch CLI Reference Manual

Fig. 1- 1. Initial Console screen.

There is no initial username or password. Just press the Enter key twice to display the CLI input cursor − DES-3326SR:4#. This is the command line where all commands are input.

Setting the Switch’s IP Address

Each Switch must be assigned its own IP Address, which is used for communication with an SNMP network manager or other TCP/IP application (for example BOOTP, TFTP). The switch’s default IP address is 10.1.1.80. You can change the default Switch IP address to fit your networking address scheme.

The switch is also assigned a unique MAC address by the factory. This MAC address cannot be changed, and can be found by typing the command reboot.

Fig. 1- 2. Reboot command

Fig. 1- 3. Boot Screen

10 Introduction

DES-3326SR Layer 3 Fast Ethernet Switch CLI Reference Manual

The switch’s MAC address can also be found from the Web management program on the Switch Information (Basic Settings) window on the Configuration menu.

The IP address for the switch must be set before it can be managed with the Web-based manager. The switch IP address can be automatically set using BOOTP or DHCP protocols, in which case the actual address assigned to the switch must be known.

The IP address may be set using the Command Line Interface (CLI) over the console serial port as follows:

1. Starting at the command line prompt, enter the commands config ipif System ipaddress xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy. Where the x’s represent the IP address to be assigned to the IP interface named System and the y’s represent the corresponding subnet mask.

2. Alternatively, you can enter config ipif System ipaddress xxx.xxx.xxx.xxx/z. Where the x’s represent the IP address to be assigned to the IP interface named System and the z represents the corresponding number of subnets in CIDR notation.

The IP interface named System on the switch can be assigned an IP address and subnet mask which can then be used to connect a management station to the switch’s Telnet or Web-based management agent.

Introduction 11

DES-3326SR Layer 3 Fast Ethernet Switch CLI Reference Manual

Fig. 1- 4. Assigning the Switch an IP Address

In the above example, the switch was assigned an IP address of

10.52.19.7 with a subnet mask of 255.0.0.0. The system message Success indicates that the command was executed successfully. The switch can now be configured and managed via Telnet and the CLI or via the Web-based management agent using the above IP address to connect to the switch.

12 Introduction

DES-3326SR Layer 3 Fast Ethernet Switch CLI Reference Manual

USING THE CONSOLE CLI

The DES-3326SR supports a console management interface that allows the user to connect to the switch’s management agent via a serial port and a terminal or a computer running a terminal emulation program. The console can also be used over the network using the TCP/IP Telnet protocol. The console program can be used to configure the switch to use an SNMP-based network management software over the network.

This chapter describes how to use the console interface to access the switch, change its settings, and monitor its operation.

Switch configuration settings are saved to nonvolatile RAM using save command. The current configuration will then be retained in the switch’s NV-RAM, and reloaded when the switch is rebooted. If the switch is rebooted without using the save command, the last configuration saved to NV-RAM will be loaded.

Connecting to the Switch

The console interface is used by connecting the Switch to a VT100-compatible terminal or a computer running an ordinary terminal emulator program (e.g., the HyperTerminal program included with the Windows operating system) using an RS-232C serial cable. Your terminal parameters will need to be set to:

Using the Console CLI 13

DES-3326SR Layer 3 Fast Ethernet Switch CLI Reference Manual

• VT-100/ANSI compatible

• 9,600 baud

• 8 data bits

• No parity

• One stop bit

• No flow control

You can also access the same functions over a Telnet interface. Once you have set an IP address for your Switch, you can use a Telnet program (in VT-100 compatible terminal mode) to access and control the Switch. All of the screens are identical, whether accessed from the console port or from a Telnet interface.

After the switch reboots and you have logged in, the console looks like this:

Fig. 2- 1. Initial Console Screen

Commands are entered at the command prompt, DES-3326SR:4#. There are a number of helpful features included in the CLI.

Entering the ? command will display a list of all of the top-level commands.

14 Using the Console CLI

DES-3326SR Layer 3 Fast Ethernet Switch CLI Reference Manual

Fig. 2- 2. The ? Command

The dir command has the same function as the ? command. When you enter a command without its required parameters, the

CLI will prompt you with a Next possible completions: message.

Fig. 2- 3. Example Command Parameter Help

In this case, the command config account was entered without the parameter <username>. The CLI will then prompt you to enter the <username> with the message, Next possible completions:. Every command in the CLI has this feature, and complex commands have several layers of parameter prompting.

Using the Console CLI 15

DES-3326SR Layer 3 Fast Ethernet Switch CLI Reference Manual

In addition, after typing any given command plus one space, you can see all of the next possible sub-commands, in sequential order, by repeatedly pressing the Tab key.

To re-enter the previous command at the command prompt, press the up arrow cursor key. The previous command will appear at the command prompt.

Fig. 2- 4. Using the Up Arrow to Re-enter a Command

In the above example, the command config account was entered without the required parameter <username>, the CLI returned the Next possible completions: <username> prompt. The up arrow cursor control key was pressed to re-enter the previous command (config account) at the command prompt. Now the appropriate User name can be entered and the config account command re-executed.

All commands in the CLI function in this way. In addition, the syntax of the help prompts are the same as presented in this manual − angle brackets < > indicate a numerical value or character string, braces { } indicate optional parameters or a choice of parameters, and brackets [ ] indicate required parameters.

If a command is entered that is unrecognized by the CLI, the toplevel commands will be displayed under the Available commands: prompt.

16 Using the Console CLI

DES-3326SR Layer 3 Fast Ethernet Switch CLI Reference Manual

Fig. 2- 5. The Next Available Commands Prompt

The top-level commands consist of commands like show or config. Most of these commands require one or more parameters to narrow the top-level command. This is equivalent to show what? or config what? Where the what? is the next parameter.

For example, if you enter the show command with no additional parameters, the CLI will then display all of the possible next parameters.

Fig. 2- 6. Next possible completions: Show Command

Using the Console CLI 17

DES-3326SR Layer 3 Fast Ethernet Switch CLI Reference Manual

In the above example, all of the possible next parameters for the show command are displayed. At the next command prompt, the up arrow was used to re-enter the show command, followed by the account parameter. The CLI then displays the user accounts configured on the switch.
