Web-based Switch Configuration
Introduction
Login to 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, Microsoft Internet Explorer, Mozilla, or Netscape. 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 Web Manager
To begin managing the Switch, simply run the browser you have 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 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 both the User Name and Password fields and click OK. This will open the Web-based user interface.
The Switch management features available in the web-based manager are explained below.

Allows the entry of an IPv4 address, Subnet Mask, and a Default Gateway for the Switch. These
fields should be of the form xxx.xxx.xxx.xxx, where each xxx is a number (represented in decimal
form) between 0 and 255. This address should be a unique address on the network assigned for
use by the network administrator.
The Switch will send out a DHCP broadcast request when it is powered up. The DHCP protocol
allows IP addresses, network masks, and default gateways to be assigned by a DHCP server. If
this option is set, the Switch will first look for a DHCP server to provide it with this information
before using the default or previously entered settings.
The Switch will send out a BOOTP broadcast request when it is powered up. The BOOTP

This allows the entry of a VLAN Name from which a management station will be allowed to
manage the Switch using TCP/IP (in-band via web manager or Telnet). Management stations that
are on VLANs other than the one entered here will not be able to manage the Switch in-band
unless their IP addresses are entered in the Security IP Management window. If VLANs have
not yet been configured for the Switch, the default VLAN contains all of the Switch's ports. There
are no entries in the Security IP Management table, by default, so any management station that
can connect to the Switch can access the Switch until a management VLAN is specified or
Management Station IP Addresses are assigned.
Toggle between Enabled and Disabled. This must be set to Enabled when setting an IP address
on this window.
IPv4 Address
Subnet Mask
Enter the desired IPv4 address to be set. The default address is 10.90.90.90.
A Bitmask that determines the extent of the subnet that the Switch is on. Should be of the form
xxx.xxx.xxx.xxx, where each xxx is a number (represented in decimal) between 0 and 255. The
value should be 255.0.0.0 for a Class A network, 255.255.0.0 for a Class B network, and
255.255.255.0 for a Class C network, but custom subnet masks are allowed.
Gateway
IP address that determines where packets with a destination address outside the current subnet
should be sent. This is usually the address of a router or a host acting as an IP gateway. If your
network is not part of an intranet, or you do not want the Switch to be accessible outside your
local network, you can leave this field unchanged.

Port
State
Speed/Duplex
Flow Control
Toggle this field to either enable or disable a given port or group of ports.
Toggle the Speed/Duplex field to either select the speed and duplex/half-duplex state of the port.
Auto denotes auto-negotiation between 10 and 100 Mbps devices, in full- or half-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 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 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.
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.

should be set at Copper.
MDIX
This can be specified as Auto, Normal, or Cross. In Normal state, the port is in MDIX mode and
can be connected to a PC NIC using a straight cable. If it is in Cross state, the port is in MDI
mode, and can be connected to a port (in MDIX mode) on another switch through a straight
cable.

DHCP Relay
The relay hops count limit allows the maximum number of hops (routers) that the DHCP messages can be relayed
through to be set. If a packet’s hop count is equal to or more than the hop count limit, the packet is dropped. The
range is between 1 and 16 hops, with a default value of 4. The relay time threshold sets the minimum time (in seconds)
that the Switch will wait before forwarding a BOOTREQUEST packet. If the value in the seconds field of the packet is
less than the relay time threshold, the packet will be dropped. The range is between 0 and 65,535 seconds, with a

This field allows an entry between 1 and 16 to define the maximum number of router hops
DHCP messages can be forwarded across. The default hop count is 4.
Allows an entry between 0 and 65535 seconds, and defines the maximum time limit for
routing a DHCP packet. If a value of 0 is entered, the Switch will not process the value in
the seconds field of the BOOTP or DHCP packet. If a non-zero value is entered, the Switch
will use that value, along with the hop count to determine whether to forward a given
BOOTP or DHCP packet.
This field can be toggled between Enabled and Disabled using the pull-down menu. It is
used to enable or disable the DHCP Agent Information Option 82 on the Switch. The default
is Disabled.
Enabled – When this field is toggled to Enabled the relay agent will insert and remove
DHCP relay information (option 82 field) in messages between DHCP servers and clients.
When the relay agent receives the DHCP request, it adds the option 82 information, and the
IP address of the relay agent (if the relay agent is configured), to the packet. Once the
option 82 information has been added to the packet it is sent on to the DHCP server. When
the DHCP server receives the packet, if the server is capable of option 82, it can implement
policies like restricting the number of IP addresses that can be assigned to a single remote
ID or circuit ID. Then the DHCP server echoes the option 82 field in the DHCP reply. The
DHCP server unicasts the reply to the back to the relay agent if the request was relayed to
the server by the relay agent. The switch verifies that it originally inserted the option 82
data. Finally, the relay agent removes the option 82 field and forwards the packet to the
switch port that connects to the DHCP client that sent the DHCP request.
Disabled - If the field is toggled to Disabled the relay agent will not insert and remove DHCP
relay information (option 82 field) in messages between DHCP servers and clients, and the

Enabled – When the field is toggled to Enable, the relay agent will check the validity of the
packet’s option 82 field. If the switch receives a packet that contains the option-82 field from
a DHCP client, the switch drops the packet because it is invalid. In packets received from
DHCP servers, the relay agent will drop invalid messages.
Disabled - When the field is toggled to Disabled, the relay agent will not check the validity of
the packet’s option 82 field.
This field can be toggled between Replace, Drop, and Keep by using the pull-down menu.
It is used to set the Switches policy for handling packets when the DHCP Agent Information
Option 82 Check is set to Disabled. The default is Replace.
Replace - The option 82 field will be replaced if the option 82 field already exists in the
packet received from the DHCP client.
Drop - The packet will be dropped if the option 82 field already exists in the packet received
from the DHCP client.
Keep -The option 82 field will be retained if the option 82 field already exists in the packet
received from the DHCP client.
This field is for you to enter the remote ID. Tick Default to use the Switch’s system MAC
address as the remote ID.
Click Apply to implement any changes that have been made.
NOTE: If the Switch receives a packet that contains the option-82 field from a DHCP
client and the information-checking feature is enabled, the switch drops the packet
because it is invalid. However, in some instances, you might configure a client with the
option-82 field. In this situation, you should disable the information-check feature so
that the switch does not remove the option-82 field from the packet. You can configure
the action that the switch takes when it receives a packet with existing option-82
information by configuring the DHCP Agent Information Option 82 Policy.
