Web-based Switch Configuration
Introduction
Login to Web Manager
Web-based User Interface
Web Pages
Introduction
All software functions of the S witc h c an be managed, configure d an d monitored via the embedded web-base d ( HTML)
interface. The Switch ca n be managed from remote statio ns anywhere on the network throug h a standard browser
such as Firefox, Microsoft Internet Explorer , Mozilla, or Netscape. The browser acts as a universal access tool and
can communicate directly with the Switc h using the H T T P protoc ol.
The Web-based m anagement module and the Consol e program (and Telnet) are diff erent ways to access the sam e
internal switching sof tware and conf igure it. Thus, al l settings encount ered in W eb-based managem ent are the sam e
as those found in the console program.
Login to Web Manager
To begin managing the Switch, s imply run the browser you have installed on your com puter 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 for the Switch is 10.90.90.90.
This opens the management module's user authentication window, as seen below.
Figure 1 - 1 Enter Network Password dialog
Enter “admin” in bot h the Us er Nam e and Pass word fields and click OK. T his will ope n the Web-based user interf ace.
The Switch management features available in the web-based manager are explained below.

The IP Address Settings options are:
Parameter Description
Static
Allows the entry of an IPv4 ad dress, Subnet Mas k, and a Default Gate way for th e Switch. T hese
fields should be of the form xxx.xxx .xxx.xxx, where e ach x xx is a number (represented in d ecim al
form) between 0 and 2 55. This addr ess should be a unique addres s on the n etwork as signed for
use by the network administrator.
DHCP
The Switch will send o ut a DHCP broadcas t request when it is powered up. Th e DHCP protocol
allows IP address es, network masks, and default g ateways to be assigned b y a DHCP server. If
this option is set, the Swit ch will first look for a DHCP server to provide it with this information
before using the default or previously entered settings.
BOOTP
The Switch will send out a BOOTP broadcast request when it is powered up. The BOOTP
protocol allows IP addres ses, network masks , and default gateways to be assigned b y a central
BOOTP server. If this optio n is set, t he Switc h will f irst look for a BOOTP s erver t o provide it with
this information before using the default or previously entered settings.

255.255.255.0 for a Class C network, but custom subnet masks are allowed.
Gateway
IP address that determ ines where packets with a destination a ddress outside the current subnet
should be sent. This is usually the ad dress of a rout er or a host ac ting as an IP gate way. If your
network is not part of an intranet, or you do not wan t the Switch to be accessible out side your

State
Toggle this field to either enable or disable a given port or group of ports.
Speed/Duplex
Toggle the Speed/Duplex field to either select the speed and duplex/half-duplex state of the port.
Auto denotes auto-negoti ation between 10 and 100 Mbps devices , in full- or half-duplex. The
Auto s etting allows th e port to autom atically determ ine the fastes t settings the d evice the por t is
connected to can handle, and then to us e those settin gs. The other opt ions are Auto, 10M Half,
10M Full, 100M Half and 100M Full, 1000M Full_Master, 1000M Full_Slave and 1000M Full.
There is no automatic adjustment of port settings with any option other than Auto.
The Switch allows the user to configure two types of gigabit connections; 1000M/Full_M and
1000M/Full_S. 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 connec tio n be t we en th e S witch port and other devic e capable of a gigabit
connection. The m aster setting (1000 M Full_Master) will allow the port to a dvertise capabilities
related to duplex, speed and physical layer type. The master setting will also determine the
master and slave relations hip between the two connected physical layers. This relationship is
necessary for establishi ng the tim ing control b etween the t wo ph ysical layers. T he timing c ontrol
is set on a master physical layer by a local sour ce. The slave setti ng (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 F ull_Mas ter, t he other s ide of the conn ection m us t be set for 1000M
Full_Slave. Any other configuration will result in a link down status for both ports.
Flow Control
Displays the flow contr ol scheme used for the various por t configurations. Ports configured f or
full-duplex use 802.3x flow control, half -duplex ports use backpressure flow control, a nd Auto
ports use an automatic selection of the two. The default is Disabled.
Address
Learning
When Enabled, desti nat io n and sour c e M AC a ddres s e s are automatically listed in the f or ward ing
table. The default setting is Enabled.
Medium Type
