The DGS-3400 Layer 2 stackable Gigabit 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 future-proof 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® DGS-3426, DGS-3427,

DGS-3450 and DGS-3426P 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 DGS-3426, DGS-3427, DGS-3450, and

DGS-3426P switches will be referred to as simply the Switch or the DGS-3450.

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 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.

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 in 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.

DGS-3450:admin#config ipif System ipaddress 10.24.22.200/255.0.0.0

Command: config ipif System ipaddress 10.24.22.200/8

Success.

DGS-3450:admin#

Figure 1-3. Assigning an IP Address

In the above example, the Switch was assigned an IP address of 10.24.22.200 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.

SING THE

ONSOLE

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 SNMPbased 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

• 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 an IP address has been set for the 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 you have logged in, the console looks like this:

802.1X

OMMANDS

The Switch implements the server-side of the IEEE 802.1X Port-based and MAC-based Network Access Control. This mechanism is intended to allow only authorized users, or other network devices, access to network resources by establishing criteria for each port on the Switch that a user or network device must meet before allowing that port to forward or receive frames.

The 802.1X commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.

OMMANDS

The TACACS / XTACACS / TACACS+ / RADIUS commands allow users to secure access to the Switch using the

TACACS / XTACACS / TACACS+ / RADIUS protocols. When a user logs in to the Switch or tries to access the administrator level privilege, he or she is prompted for a password. If TACACS / XTACACS / TACACS+ / RADIUS authentication is enabled on the Switch, it will contact a TACACS / XTACACS / TACACS+ / RADIUS server to verify the user. If the user is verified, he or she is granted access to the Switch.

There are currently three versions of the TACACS security protocol, each a separate entity. The Switch’s software supports the following versions of TACACS:

• TACACS (Terminal Access Controller Access Control System) —Provides password checking and authentication, and notification of user actions for security purposes utilizing via one or more centralized TACACS servers, utilizing the UDP protocol for packet transmission.

• Extended TACACS (XTACACS) — An extension of the TACACS protocol with the ability to provide more types of authentication requests and more types of response codes than TACACS. This protocol also uses UDP to transmit packets.

• TACACS+ (Terminal Access Controller Access Control System plus) — Provides detailed access control for authentication for network devices. TACACS+ is facilitated through Authentication commands via one or more centralized servers. The TACACS+ protocol encrypts all traffic between the Switch and the TACACS+ daemon, using the TCP protocol to ensure reliable delivery.

The Switch also supports the RADIUS protocol for authentication using the Access Authentication Control commands.

RADIUS or Remote Authentication Dial In User Server also uses a remote server for authentication and can be responsible for receiving user connection requests, authenticating the user and returning all configuration information necessary for the client to deliver service through the user. RADIUS may be facilitated on this Switch using the commands listed in this section.

In order for the TACACS / XTACACS / TACACS+ / RADIUS security function to work properly, a TACACS / XTACACS /

TACACS+ / RADIUS server must be configured on a device other than the Switch, called a server host and it must include usernames and passwords for authentication. When the user is prompted by the Switch to enter usernames and passwords for authentication, the Switch contacts the TACACS / XTACACS / TACACS+ / RADIUS server to verify, and the server will respond with one of three messages: a. The server verifies the username and password, and the user is granted normal user privileges on the Switch. b. The server will not accept the username and password and the user is denied access to the Switch. c. The server doesn’t respond to the verification query. At this point, the Switch receives the timeout from the server and then moves to the next method of verification configured in the method list.

The Switch has four built-in server groups, one for each of the TACACS, XTACACS, TACACS+ and RADIUS protocols.

These built-in server groups are used to authenticate users trying to access the Switch. The users will set server hosts in a preferable order in the built-in server group and when a user tries to gain access to the Switch, the Switch will ask the first server host for authentication. If no authentication is made, the second server host in the list will be queried, and so on. The built-in server group can only have hosts that are running the specified protocol. For example, the TACACS server group can only have TACACS server hosts.

The administrator for the Switch may set up five different authentication techniques per user-defined method list

(TACACS / XTACACS / TACACS+ / RADIUS / local / none) for authentication. These techniques will be listed in an order preferable, and defined by the user for normal user authentication on the Switch, and may contain up to eight authentication techniques. When a user attempts to access the Switch, the Switch will select the first technique listed for authentication. If the first technique goes through its server hosts and no authentication is returned, the Switch will then go to the next technique listed in the server group for authentication, until the authentication has been verified or denied, or the list is exhausted.

xStack

DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch CLI Manual

Please note that user granted access to the Switch will be granted normal user privileges on the Switch. To gain access to admin level privileges, the user must enter the enable admin command and then enter a password, which was previously configured by the administrator of the Switch.

NOTE: TACACS, XTACACS and TACACS+ are separate entities and are not compatible. The Switch and the server must be configured exactly the same, using the same protocol. (For example, if the

Switch is set up for TACACS authentication, so must be the host server.)

The Access Authentication Control commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.

DGS-3450:admin# create authen_login method_list_name login_list_1

Command: create authen_login method_list_name login_list_1

Success.

DGS-3450:admin#

config authen_login

Purpose

Syntax

Description

Parameters

Restrictions

This command is used to configure a user-defined or default method list of authentication methods for users attempting to log in to the Switch.

config authen_login [default | method_list_name <string 15>] method {tacacs | xtacacs

| tacacs+ | radius | server_group <string 15> | local | none}

Configures a user-defined or default method list of authentication methods for users attempting to log in to the Switch. The method sequence will affect the authentication result.

For example, if the user specifies tacacs+ first, then tacacs and local, when the user tries to log in, the authentication request will be sent to the first server host in the tacacs+ built-in server group. If the first server host in the tacacs+ group is missing, the authentication request will be sent to the second server host in the tacacs+ group, and so on. If all server hosts in the tacacs+ group are missing, the authentication request will be sent to the first server host in the tacacs group. If all server hosts in the tacacs group are missing, the local account database in the device will be used to authenticate the user. When a user logs in to the device successfully, using either the tacacs/xtacacs/tacacs+/radius built-in, user-defined server groups methods, or none, only the “user” privilege level will be assigned. If the user wants to access admin privilege level, the user must use the “enable admin” command to promote the privilege level. However, when the local method is used, the privilege level will depend on the account privilege level stored in the local device.

default - Specify the default method list of authentication methods.

method_list_name - Specify the user-defined method list of authentication methods.

tacacs - Specify authentication by the built-in server group “tacacs”.

xtacacs - Specify authentication by the built-in server group “xtacacs”.

radius - Specify authentication by the built-in server group “radius”.

server_group - Specify authentication by the user-defined server group.

local - Specify authentication by the local user account database in the device.

none - Specify no authentication.

Only Administrator can issue this command.
