Chapter 1 Web-based Switch Configuration
Introduction
Login to the Web Manager
Web-based User Interface
Web Pages
Introduction
All software functions of the DES-3200 Series switches can be managed, configured and monitored via the
embedded web-based (HTML) interface. Manage the Switch from remote stations anywhere on the network
through a standard browser. The browser acts as a universal access tool and can communicate directly with the
Switch using the HTTP protocol.
The Web-based management module and the Console program (and Telnet) are different ways to access the
same internal switching software and configure it. Thus, all settings encountered in web-based management are
the same as those found in the console program.
Login to the Web Manager
To begin managing the Switch, simply run the browser installed on your computer and point it to the IP address you
have defined for the device. The URL in the address bar should read something like: http://123.123.123.123, where
the numbers 123 represent the IP address of the Switch.
NOTE: The factory default IP address is 10.90.90.90.
This opens the management module's user authentication window, as seen below.
Figure 1-1 Enter Network Password window
Leave both the User Name field and the Password field blank and click OK. This will open the Web-based user
interface. The Switch management features available in the web-based manager are explained below.

Device Information
This window contains the main settings for all the major functions for the Switch. It appears automatically when you
log on to the Switch. To return to the Device Information window after viewing other windows, click the DES-3200
Series link.
The Device Information window shows the Switch’s MAC Address (assigned by the factory and unchangeable), the
Boot PROM Version, Firmware Version, Hardware Version, and many other important types of information. This is
helpful to keep track of PROM and firmware updates and to obtain the Switch’s MAC address for entry into another
network device’s address table, if necessary. In addition, this window displays the status of functions on the Switch
to quickly assess their current global status.
Many functions are hyper-linked for easy access to enable quick configuration from this window.

Figure 2-3 Port Settings window
To configure switch ports:
1. Choose the port or sequential range of ports using the From Port and To Port drop-down menus.
2. Use the remaining drop-down menus to configure the parameters described below:
The fields that can be configured are described below:
Parameter Description
From Port / To Port
Select the appropriate port range used for the configuration here.
State
Toggle the State field to either enable or disable a given port or group of ports.
Speed/Duplex Toggle the Speed/Duplex field to select the speed and full-duplex/half-duplex state of the
port. Auto denotes auto-negotiation among 10, 100 and 1000 Mbps devices, in full- or
half-duplex (except 1000 Mbps which is always full duplex). The Auto setting allows the
port to automatically determine the fastest settings the device the port is connected to
can handle, and then to use those settings. The other options are 10M Half, 10M Full,
100M Half, 100M Full, 1000M Full_Master, and 1000M Full_Slave. There is no automatic
adjustment of port settings with any option other than Auto.
The Switch allows the user to configure three types of gigabit connections; 1000M
Full_Master, and 1000M Full_Slave. Gigabit connections only support full duplex
connections and take on certain characteristics that are different from the other choices
listed.
The 1000M Full_Master and 1000M Full_Slave parameters refer to connections running
a 1000BASE-T cable for connection between the Switch port and other device capable

xStack® DES-3200 Series Layer 2 Managed Fast Ethernet Switch
8
of a gigabit connection. The master setting (1000M Full_Master) will allow the port to
advertise capabilities related to duplex, speed and physical layer type. The master
setting will also determine the master and slave relationship between the two connected
physical layers. This relationship is necessary for establishing the timing control between
the two physical layers. The timing control is set on a master physical layer by a local
source. The slave setting (1000M Full_Slave) uses loop timing, where the timing comes
from a data stream received from the master. If one connection is set for 1000M
Full_Master, the other side of the connection must be set for 1000M Full_Slave. Any
other configuration will result in a link down status for both ports.
Flow Control Displays the flow control scheme used for the various port configurations. Ports
configured for full-duplex use 802.3x flow control, half-duplex ports use backpressure
flow control, and Auto ports use an automatic selection of the two. The default is
Disabled.
Address Learning Enable or disable MAC address learning for the selected ports. When Enabled,
destination and source MAC addresses are automatically listed in the forwarding table.
When address learning is Disabled, MAC addresses must be manually entered into the
forwarding table. This is sometimes done for reasons of security or efficiency. See the
section on Forwarding/Filtering for information on entering MAC addresses into the
forwarding table. The default setting is Enabled.
MDIX Auto - Select auto for auto sensing of the optimal type of cabling.
Normal - Select normal for normal cabling. If set to normal state, the port is in MDI mode
and can be connected to a PC NIC using a straight-through cable or a port (in MDI
mode) on another switch through a cross-over cable.
Cross - Select cross for cross cabling. If set to cross state, the port is in MDIX mode, and
can be connected to a port (in MDI mode) on another switch through a straight cable.
Medium Type
If configuring the Combo ports, this defines the type of transport medium to be used.
Click the Apply button to implement changes made.
Click the Refresh button to refresh the display section of this page.

PoE
The DES-3200-28P and DES-3200-52P switches support Power over Ethernet (PoE) as defined by the IEEE
802.3af and 802.3at standard. Ports 1 to 24 for DES-3200-28P and ports 1 to 48 for DES-3200-52P can supply
about 48 VDC power to Powered Devices (PDs) over Category 5 or Category 3 UTP Ethernet cables.
The Switch follows the standard Power Sourcing Equipment (PSE) pinout Alternative A, whereby power is sent out
over pins 1, 2, 3 and 6. The Switches work with all D-Link 802.3af capable devices.

The Switch includes the following PoE features:
1. Auto-discovery recognizes the connection of a Powered Device (PD) and automatically sends power to it.
2. The Auto-disable function will activate when the port current value exceeds 350mA or when a short
happens.
For 802.3af capable devices, evaluate the table below, containing the correct power level per class and their
respective usage options.

PoE System Settings
This window is used to assign a power limit and power disconnect method for the whole PoE system. When the
total consumed power exceeds the power limit configured in this window, the PoE controller (located in the PSE)
disconnects the power to prevent overloading the power supply.
To view the following window, click System Configuration > PoE > PoE System Settings, as show below:

Figure 2-7 PoE System Settings window
The following parameters can be configured:
Parameter Description
Power Limit Sets the limit of power to be used from the Switch’s power source to PoE ports. The user
may configure a Power Limit between 37W and 188W for the DES-3200-28P, and
between 37W and 370W for DES-3200-52P.
Power Disconnect
Method The PoE controller uses either Deny Next Port or Deny Low Priority Port to offset the
power limit being exceeded and keeps the Switch’s power at a usable level. Use the drop
down menu to select a Power Disconnect Method. The default Power Disconnect
Method is Deny Next Port. Both Power Disconnection Methods are described below:
Deny Next Port – After the power limit has been exceeded, the next port attempting to
power up is denied, regardless of its priority. If Power Disconnection Method is set to
Deny Next Port, the system cannot utilize out of its maximum power capacity. The
maximum unused watt is 19W.
Deny Low Priority Port – After the power limit has been exceeded, the next port
attempting to power up causes the port with the lowest priority to shut down so as to
allow the high-priority and critical priority ports to power up.
Legacy PD
Use the drop-down menu to enable or disable detecting legacy PDs signal.
