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.

The DES-3528/DES-3552 Series Layer 2 stackable Fast Ethernet Switch Series are members of the D-Link xStack family. Ranging from 10/100Mbps edge Switches to core gigabit Switches, the xStack Switch family has been futureproof designed to provide a stacking architecture with fault tolerance, flexibility, port density, robust security and maximum throughput with a user-friendly management interface for the networking professional.

This manual provides a reference for all of the commands contained in the CLI for the xStack 3528P, DES-3528DC, DE S-3552 and DES-3552P series of Switches. Configuration and management of the Switch via the Web-based management agent is discussed in the User’s Guide.

NOTE: For the remainder of this manual, all versions of the DES-3528, DES-3528P, DES-3528DC, DES-3552 and DES-3552P Switches will be referred to as simply the Switch or the DES-3528/52 Series.

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 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.

Command Line Interface

Firmware: Build 3.00.012

UserName:

There is no initial username or password. Just press the Enter key twice to display the CLI input cursor − DES- 3528:admin# . 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. Users 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.

The Switch’s MAC addres s 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 Sw itch must be set before it can be managed w ith the Web-based manager. The S witch IP address can be autom aticall y set using BOOTP or D HCP pro tocols, in which cas e the actua l address as signed t o 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 repres ent the IP address to be as signed to the IP interf ace named System and the y’s represent the corresponding subnet mask.

2. Alternativel y, users c an enter config ipif S ystem ipaddress xx x.xxx.xxx.xxx/z . Where the x’s re present the IP address to be assig ned t o the IP i nterf ace n am ed System an d the z represents the c orres pondi ng num ber of subnets in CIDR notation.

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

Command: config ipif System ipaddress 10.24.73.21/8

Success.

In the above exam ple, the Switch w as assigned an IP address of 10.24 .73.21 with a sub net 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, S NMP MIB bro wser and the CLI or via th e Web-based management agent using t he above IP address to connect to the Switch.

Using the Console CLI

The DES-3528/52 Series 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 re loa ded when the S witc h 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 term inal or a computer running an ordinary terminal em ulator program (e.g., the HyperTerminal program included with the W indows operating s ystem) using an RS-232C serial cable. Your terminal parameters will need to be set to:

• VT-100 compatible

• 115200 baud

• 8 data bits

• No parity

• One stop bit

• No flow control

Users can also access the same functions over a Telnet interface. Once users have set an IP address for your Switch, users 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 users have logged in, the console looks like this:

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

In addition, after typing an y given com mand plus one space, user s can see all of the next poss ible sub-commands, in sequential order, by repeatedly pressing the Tab key.

To re-enter the previo us command at the comm and prompt, press the up arr ow cursor key. The pre vious command will appear at the command prompt.

The up arrow cursor c ontrol ke y was pressed to re-enter the previous com mand (config account) at the command prompt. Now the appropriat e 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.

This command creates a new SNMP user and adds the user to an SNMP group that is also created by this command. SNMP ensures:

Message integrity − Ensures that packets have not been tampered with during transit. Authentication − Determines if an SNMP message is from a valid source. Encryption − Scrambles the contents of messages to prevent it from being viewed by an

<user_name 32> − An alphanumeric name of up to 32 characters that will identify the new SNMP user.

<groupname 32> − An alphanumeric name of up to 32 characters 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 string 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 string 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 string of between 8 and 20 characters that

will be used to authorize the agent to receive packets for the host.

• <auth_key 40-40> - Enter an alphanumeric string 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> - Enter 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 the agent.

none – Adding this parameter will add no encryption.
