Chapter 1 Web-based Switch Configuration
Introduction
Login to the Web Manager
Web-based User Interface
Web Pages
Introduction
All software functions of the Switch can be managed, configured and monitored via the embedded web-based (HTML)
interface. The Switch can be managed from remote stations anywhere on the network through a standard browser
such as Firefox, Safari, or Microsoft Internet Explorer. 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

Port Configuration
Port Settings
This page used to configure the details of the switch ports. To view the following window, click System Configuration
> Port Configuration > Port Settings, as shown below:
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 pull-down menus.
2. Use the remaining pull-down menus to configure the parameters described below:
The fields that can be configured are described below:
Parameter Description
Unit Select the unit to configure.
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, 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 three types of gigabit connections; 1000M
Full_Master, 1000M Full_Slave, and 1000M Full. 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 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.
