Introduction 9 1 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:

10 Introduction 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

Introduction 11 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.

12 Introduction 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.

Using the Console CLI 13 2 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 non- volatile 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:

14 Using the Console CLI • 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.

Using the Console CLI 15 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 . The CLI will then prompt you to enter the with the message, Next possible completions:. Every command in the CLI has this feature, and complex commands have several layers of parameter prompting.

16 Using the Console CLI 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 , the CLI returned the Next possible completions: 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 top- level commands will be displayed under the Available commands: prompt.

Using the Console CLI 17 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

18 Using the Console CLI 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 19 3 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. Purpose Encloses a variable or value that must be specified. Syntax create ipif vlan ipaddress Description In the above syntax example, you must supply an IP interface name in the space, a VLAN name in the space, and the network address in the space. Do not type the angle brackets. Example Command create ipif Engineering vlan Design ipaddress 10.24.22.5/255.0.0.0

20 Command Syntax [square brackets] Purpose Encloses a required value or set of required arguments. One or more values or arguments can be specified. Syntax create account [admin/user] Description In the above syntax example, you must specify either an admin or a user level account to be created. Do not type the square brackets. Example Command create account admin / slash Purpose Separates two or more mutually exclusive items in a list − one of which must be entered. Syntax show snmp [community/trap receiver/detail] Description In the above syntax example, you must specify either community, trap receiver, or detail. Do not type the backslash. Example Command show snmp community

Command Syntax 21 / slash Command {braces} Purpose Encloses an optional value or set of optional arguments. Syntax config igmp [/all] {version /query_interval /max_response_time / robustness_variable /last_member_query_interval /state [enabled/disabled]} Description In the above syntax example, you must choose to enter an IP interface name in the space or all, but version , query_interval , max_response_time , robustness_variable , last_member_query_interval , and state [enabled/disabled] are all optional arguments. You can specify any or all of the arguments contained by braces. Do not type the braces. Example command config igmp all version 2

22 Command Syntax Line Editing Key Usage Delete In certain formats, deletes highlighted characters 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. Insert Can be toggled on or off. When toggled on, inserts text at the current cursor position and shifts the remainder of the line to the left. Left Arrow Moves the cursor to the left. Right Arrow Moves the cursor to the right. Tab Shifts the cursor to the next field to the left. Multiple Page Display Control Keys Space Displays the next page. CTRL+c Stops the display of remaining pages when multiple pages are to be displayed. ESC Stops the display of remaining pages when multiple pages are to be displayed. n Displays the next page.
