xStack® DGS-3120 Series Layer 3 Managed Gigabit Ethernet Switch CLI Reference Guide

Chapter 1 Using Command Line

Interface

The Switch can be managed through the Switch’s serial port, Telnet, SNMP 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. Every command will be introduced in terms of purpose, format, description, parameters, and examples. Configuration and management of the Switch via the Web-based management agent are discussed in the Web UI Reference Guide. For detailed information on installing hardware please also refer to the Hardware Installation Guide.

1-1 Accessing the Switch via the Serial Port

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

•115200 baud

•no parity

•8 data bits

•1 stop bit

A computer running a terminal emulation program capable of emulating a VT-100 terminal and a serial port configured as above are then connected to the Switch’s Console port via an included RS-232 to RJ-45 convertor cable.

With the serial port properly connected to a management computer, the following screen should be visible.

There is no initial username or password. Just press the Enter key twice to display the CLI input cursor − DGS-3120-24TC:admin# . This is the command line where all commands are input.

NOTE: When Switches with different modes or different firmware versions are stacked together, the following warning message will appear after the initial login:

1-2 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 10.90.90.90. You can change the default Switch IP address to meet the specification of 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 on the initial boot console screen – shown below.

Boot Procedure

V3.00.501

-------------------------------------------------------------------------------

Power On Self	Test ........................................	100	%
MAC Address	: 10-BF-48-D0-E0-E0
H/W Version	: B1
Please Wait, Loading V4.00.015 Runtime Image ..............		100	%
UART init .................................................		100	%
Starting runtime image
Device Discovery ..........................................			|

The Switch’s MAC address can also be found in 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.

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.

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.

2

xStack® DGS-3120 Series Layer 3 Managed Gigabit Ethernet Switch CLI Reference Guide

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.

DGS-3120-24TC:admin# config ipif System ipaddress 10.24.22.100/255.0.0.0

Command: config ipif System ipaddress 10.24.22.100/8

Success.

DGS-3120-24TC:admin#

In the above example, the Switch was assigned an IP address of 10.24.22.100 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, SNMP MIB browser and the CLI or via the Web-based management agent using the above IP address to connect to the Switch.

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.

DGS-3120-24TC:admin#?

When entering a command without its required parameters, the CLI will prompt you with a Next possible completions: message.

xStack® DGS-3120 Series Layer 3 Managed Gigabit Ethernet Switch CLI Reference Guide

DGS-3120-24TC:admin#config account

Command: config account Next possible completions: <username 15>

DGS-3120-24TC:admin#

In this case, the command config account was entered with the parameter <username 15>. The CLI will then prompt to enter the <username 15> with the message, Next possible completions:. Every command in the CLI has this feature, and complex commands have several layers of parameter prompting.

In addition, after typing any given command plus one space, users 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.

DGS-3120-24TC:admin#config account

Command: config account Next possible completions: <username 15>

DGS-3120-24TC:admin#config account

In the above example, the command config account was entered without the required parameter

<username 15>, the CLI returned the Next possible completions: <username 15> prompt. The up arrow cursor control key was pressed to re-enter the previous command (config account) at the command prompt. Now the appropriate username 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 top-level commands will be displayed under the Available commands: prompt.
