INTRODUCTION

The DGS-3024 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 terminal and a serial port configured as above is then connected to the Switch’s serial port via an RS-232 DB-9 cable.

With the serial port properly connected to a management computer, the following screen should be visible. If this screen does not appear, try pressing Ctrl+r to refresh the console screen.

Figure 1-1. Initial CLI screen

There is no initial username or password. Just press the Enter key twice to display the CLI input cursor − DGS-3024:4#. This is the command line where all commands are input.

DGS-3024 Layer 2 Switch CLI Reference Manual

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.

Figure 1-2. Boot Screen

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.

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.

2

DGS-3024 Layer 2 Switch CLI Reference Manual

Figure 1-3. Assigning an IP Address

In the above example, the Switch was assigned an IP address of 10.53.13.111 with a subnet mask of 255.0.0.0 (8 in CIDR from). 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.

USING THE CONSOLE CLI

The DGS-3024 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.

Note: Switch configuration settings are saved to non-volatile RAM using the 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:

•VT-100 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:

DGS-3024 Layer 2 Switch CLI Reference Manual

Figure 2-1. Console Screen after login

Commands are entered at the command prompt, DGS-3024:4#.

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.

Figure 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.

5

DGS-3024 Layer 2 Switch CLI Reference Manual

Figure 2-3. Example Command Parameter Help

In this case, the command show was entered without a parameter. The CLI will then prompt you to enter the next possible completions 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, you can see all of the next possible sub-commands, in sequential order, by repeatedly pressing the Tab key.

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

Figure 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.

6

DGS-3024 Layer 2 Switch CLI Reference Manual

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.

Figure 2-5. The Next Available Commands Prompt

The top-level commands consist of commands such as 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.

Figure 2-6. Next possible completions: show command

7

DGS-3024 Layer 2 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.

COMMAND SYNTAX

The following symbols are used to describe how command entries are made and values and arguments are specified in this manual. The online help contained in the CLI and available through the console interface uses the same syntax.

Note: All commands are case-sensitive. Be sure to disable Caps Lock or any other unwanted function that changes text case.

<angle brackets>

Purpose	Encloses a variable or value that must be specified.
Syntax	create ipif <ipif_name> vlan <vlan_name 32> ipaddress
	<network_address>
Description	In the above syntax example, you must supply an IP interface name in the
	<ipif_name> space, a VLAN name in the <vlan_name 32> space, and the
	network address in the <network_address> space. Do not type the angle
	brackets.
Example	create ipif Engineering vlan Design ipaddress 10.24.22.5/255.0.0.0
Command

DGS-3024 Layer 2 Switch CLI Reference Manual

{braces}

Purpose	Encloses an optional value or set of optional arguments.
Syntax	reset {[config | system]}
Description	In the above syntax example, you have the option to specify config or
	system. It is not necessary to specify either optional value, however the
	effect of the system reset is dependent on which, if any, value is specified.
	Therefore, with this example there are three possible outcomes of
	performing a system reset. See the chapter Basic Commands for more
	details about the reset command.
Example	reset config
command

Line Editing Key Usage

Delete	Deletes the character under the cursor and then shifts the remaining
	characters in the line to the left.
Backspace	Deletes the character to the left of the cursor and shifts the remaining
	characters in the line to the left.
Left Arrow	Moves the cursor to the left.
Right Arrow	Moves the cursor to the right.
Up Arrow	Repeat the previously entered command. Each time the up arrow is
	pressed, the command previous to that displayed appears. This way it is
	possible to review the command history for the current session. Use the
	down arrow to progress sequentially forward through the command history
	list.
Down Arrow	The down arrow will display the next command in the command history
	entered in the current session. This displays each command sequentially as
	it was entered. Use the up arrow to review previous commands.
Tab	Shifts the cursor to the next field to the left.

NETWORK MANAGEMENT (SNMP) COMMANDS

The network management commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.

The DGS-3024 supports the Simple Network Management Protocol (SNMP) versions 1, 2c, and 3. The user may specify which version of the SNMP to use to monitor and control the Switch. The three versions of SNMP vary in the level of security provided between the management station and the network device. The following table lists the security features of the three SNMP versions:

SNMP	Authentication Method	Description
Version
v1	Community String	Community String is used for authentication − NoAuthNoPriv
v2c	Community String	Community String is used for authentication − NoAuthNoPriv
v3	Username	Username is used for authentication − NoAuthNoPriv
v3	MD5 or SHA	Authentication is based on the HMAC-MD5 or HMAC-SHA algorithms
		− AuthNoPriv
v3	MD5 DES or SHA DES	Authentication is based on the HMAC-MD5 or HMAC-SHA algorithms
		− AuthPriv.
		DES 32-bit encryption is added based on the CBC-DES (DES-32)
		standard

Command	Parameters
create snmp user	<username 32> <groupname 32> {encrypted [by_password
	auth [md5 <auth_password 8-16> | sha <auth_password 8-
	20>] priv [none | des <priv_password 8-16>] | by_key auth

create snmp user

Purpose	Used to create a new SNMP user and adds the user to an SNMP
	group that is also created by this command.
Syntax	create snmp user <username 32> <groupname 32> {encrypted
	[by_password auth [md5 <auth_password 8-16> | sha
	<auth_password 8-20>] priv [none | des <priv_password 8-16>] |

create snmp user

that will identify the SNMP group the new SNMP user will be associated with.

encrypted – Allows the user to choose a type of authorization for authentication using SNMP. The user may choose:

•by_password – Requires the SNMP user to enter a password for authentication and privacy. The password is defined by specifying the auth_password below. This method is recommended.

•by_key – Requires the SNMP user to enter a encryption key for authentication and privacy. The key is defined by specifying the key in hex form below. This method is not recommended.

auth - The user may also choose the type of authentication algorithms used to authenticate the snmp user. The choices are:

•md5 − Specifies that the HMAC-MD5-96 authentication level will be used. md5 may be utilized by entering one of the following:

<auth password 8-16> - An alphanumeric sting of between 8 and 16 characters that will be used to authorize the agent to receive packets for the host.

<auth_key 32-32> - Enter an alphanumeric sting of exactly 32 characters, in hex form, to define the key that will be used to authorize the agent to receive packets for the host.

•sha − Specifies that the HMAC-SHA-96 authentication level will be used.

<auth password 8-20> - An alphanumeric sting of between 8 and 20 characters that will be used to authorize the agent to receive packets for the host.

<auth_key 40-40> - An alphanumeric sting of exactly 40 characters, in hex form, to define the key that will be used to authorize the agent to receive packets for the host.

priv – Adding the priv (privacy) parameter will allow for encryption in addition to the authentication algorithm for higher security. The user may choose:

•des – Adding this parameter will allow for a 56-bit encryption to be added using the DES-56 standard using:

<priv_password 8-16> - An alphanumeric string of between 8 and 16 characters that will be used to encrypt the contents of messages the host sends to the agent.

<priv_key 32-32> - An alphanumeric key string of exactly 32 characters, in hex form, that will be used to encrypt the contents of messages the host sends to
