xStack DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch CLI Manual

Introduction

The DES-3800 series is a member of the D-Link xStack switch family. xStack is a complete family of

stackable devices that ranges from edge 10/100Mbps switches to core Gigabit switches. xStack provides

unsurpassed performance, fault tolerance, scalable flexibility, robust security, standard-based

interoperability and an impressive support for 10Gigabit technology to future-proof departmental and

enterprise network deployments with an easy migration path.

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 Manual.

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 o 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 −

DES-3800:4#.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 10.90.90.90. 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 zrepresents 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.

Figure 1-3. Assigning an IP Address

In the above example, the Switch was assigned an IP address of 10.41.44.254 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.

xStack DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch CLI Manual

Using the Console CLI

The Switch 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

• 9600 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:

Figure 2- 1. Initial Console Screen after logging in

Commands are entered at the command prompt, DES-3800:4#.

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

When you enter a command without its required parameters, the CLI will prompt you with a Next

possible completions: message.
