1. Introduction
This manual’s feature descriptions are based on the software release 1.16. The features listed here are the subset of
features that are supported by the DGS-3130 Series Switch.
Audience
This reference manual is intended for network administrators and other IT networking professionals responsible for
managing the Switch by using the Web User Interface (Web UI). The Web UI is the secondary management interface
to the DGS-3130 Series Switch, which will be generally be referred to simply as the “Switch” within this manual. This
manual is written in a way that assumes that you already have the experience and knowledge of Ethernet and modern
networking principles for Local Area Networks.
Other Documentation
The documents below are a further source of information in regards to configuring and troubleshooting the Switch. All
the documents are available either from the CD, bundled with this Switch, or from the D-Link website. Other
documents related to this Switch are:
•DGS-3130 Series Hardware Installation Guide
•DGS-3130 Series CLI Reference Guide
Conventions
Convention Description
Boldface Font Indicates a button, a toolbar icon, menu, or menu item. For example: Open the
File menu and choose Cancel. Used for emphasis. May also indicate system
messages or prompts appearing on screen. For example: You have mail. Bold
font is also used to represent filenames, program names and commands. For
example: use the copy command.
Initial capital letter Indicates a window name. Names of keys on the keyboard have initial capitals.
For example: Click Enter.
Menu Name > Menu Option Indicates the menu structure. Device > Port > Port Properties means the Port
Properties menu option under the Port menu option that is located under the
Device menu.
Blue Courier Font
This convention is used to represent an example of a screen console display
including example entries of CLI command input with the corresponding output.
Notes, Notices, and Cautions
Below are examples of the three types of indicators used in this manual. When administering your Switch using the
information in this document, you should pay special attention to these indicators. Each example below provides an
explanatory remark regarding each type of indicator.
NOTE: A note indicates important information that helps you make better use of your device.
NOTICE: A notice indicates either potential damage to hardware or loss of data and tells you how to
avoid the problem.

Web User Interface (Web UI)
Management Options
The Switch provides multiple access platforms that can be used to configure, manage, and monitor networking
features available on this Switch. Currently there are three management platforms available which are described
below.
Command Line Interface (CLI)
The Switch can be managed, out-of-band, by using the console port or the MGMT port on the front panel of the
Switch. Alternatively, the Switch can also be managed, in-band, by using a Telnet connection to any of the LAN ports
on the Switch. The command line interface provides complete access to all Switch management features.
For more detailed information about the CLI, refer to the DGS-3130 Series CLI Reference Guide.
SNMP-based Management
The Switch can be managed with an SNMP-compatible Network Management System (NMS). The Switch supports
SNMP v1/v2c/v3. The SNMP agent on the Switch decodes the incoming SNMP messages and responds to requests
with MIB objects stored in the database. The SNMP agent on the Switch updates the MIB objects to generate
statistics and counters.
Web User Interface (Web UI)
The Web UI can be accessed from any computer running web browsing software from its MGMT port or LAN port
when it is connected to any of the RJ45 or SFP/SFP+ ports. The Web UI on the Switch can also be accessed using an
HTTPS (SSL) connection.
This management interface is a more graphical representation of the features that can be viewed and configured on
the Switch. Most of the features available through the CLI can be accessed through the Web UI. Web browsers like
Microsoft Internet Explorer, Mozilla Firefox, or Google Chrome can be used.
NOTE: The Command Line Interface (CLI) provides the functionality of managing, configuring, and
monitoring all of the software features that are available on the Switch.
Logging into the Web UI
To access the Web UI open a standard web browser and enter the IP address of the Switch into the address bar of
the browser and press the ENTER key.
NOTE: The default IP address of the Switch is 10.90.90.90, with a subnet mask of 255.0.0.0.

After pressing the ENTER key, the following authentication window should appear, as shown below.
Figure 2-2 Web UI Login Window
When connecting to the Web UI of the Switch for the first time, leave the User Name and Password fields blank and
click Login since there are no login user accounts created by default on the Switch.
NOTE: After a user account was created, login credentials will be required to access the Web UI.
During the sending and receiving of the login password to and from the Switch, this
information will be protected using TLS/SSL to prevent attackers from snooping this
information to gain unauthorized access to the Switch.
Web User Interface (Web UI)
The Web UI provides access to various Switch configuration and management windows. It allows the user to view
performance statistics, and permits graphical monitoring of the system’s status.
Areas of the User Interface
The figure below shows the user interface. Four distinct areas that divide the user interface, as described in the table.
