1 Introduction
The 24/2Giga web smart switch is a high performance web-smart layer 2 switch that provides users
with 24 switched 10/100/1000Mbps Ethernet ports and 2 shared mini-GBIC ports with
auto-detection function. The management function can be accessed via out of band RS-232 terminal
port connection and also via in-band IP access from any port and local or remote location. This
switch is suitable for enterprise companies or SOHO users who want to build up a high speed
network or backbone. With single-mode or multi-mode fibre transceivers you can link remote users
or share remote resources. A web interface management facility provides control capability over
TCP/IP. This makes operation easy to manage with a browser at the local or remote side.
Non-blocking and maximum wire speed performance is supported on all switched ports. It also
supports an auto-negotiation and MDI/-MDIX function on all switched 24 10/100/1000M RJ-45
Gigabit ports.
This switch supports both port-based VLAN and 802.1q (tag-based) VLAN. To increase bandwidth
application, it supports 4 trunk groups with up to 8 ports. Moreover, these trunk ports provide
redundant back-up should one or more ports malfunction in that trunking group.

1.1 Start to Manage This Switch
Plug-in the power source to power-up the switch. After the switch is powered-on and in a ready state
(both the LED indicators POWER and DIAG are lit), you can use any in-band Ethernet port to
remotely manage it through a web browser. Alternatively use an RS-232 cable to plug-in the console
port (on the rear panel) to locally do the simple system configurations by using the command line
interface (CLI). The default IP and related settings for this interface are shown as follows:
„
„
„
IP address: 192.168.223.100
Network mask: 255.255.248.0
Default gateway:192.168.223.254
Try to use the default IP shown above to PING the switch from your PC to make sure the network
connection is successful. The default IP address on this switch can be modified later for your needs.
If you encounter access problems you can just locally connect to the console port to get the correct
IP address for this system.
Now you can use the browser to launch the web-managed interface for this switch. This system only
supports Microsoft Internet Explorer for web interface configuration.
The login dialog box (shown as below) will show up first when the switch’s IP address is entered in
your browser.
Use the default username and password shown as below to complete the login procedure:
„

2.3 About the Copper/Fibre Media Auto-Detection
This switch provides an option to use either copper or fibre media for the first two combo ports -
Port1 and Port2. This means that you can setup the link by using either copper media to plug-in to
the copper port or use fibre media to plug-in the mini-GBIC port. This switch will automatically
detect which media is plugged into the port. If both copper and fibre media are plugged in the fibre
media has higher priority than the copper to setup the link; the link on the copper media will
be down. The link for the copper media will be re-setup after the fibre media is un-plugged. The
Port Status page will show the current link status according to the active media linking.
NOTE: The link status will take 10 seconds to be stable after any port mode changing (copper /
fibre media switching or auto / force mode changing for fibre media.) for combo ports.

2.5 Port-Based VLAN
The port-based VLAN divides the ports into different Virtual LAN domain groups. After setting the
port-based VLAN, the different VLAN groups can’t access each other. The VLAN initial setting
page is shown as below:
You need to click the Enable/Disable link text to enable/disable the port-based VLAN. When
port-based VLAN is enabled, the 802.1Q VLAN will be disabled automatically. The port-based
VLAN and 802.1Q VLAN cannot co-exist at the same time.
You can add, delete, and modify the port-based VLAN for your needs. This system supports up to
32 port-based VLAN groups for manual entry. The following pages will describe in detail how to
configure the port-based VLAN.
NOTE: A default port-based VLAN entry (No=1) is initially created by the system. This VLAN
entry contains members for all ports. It can be regarded as no VLAN function because all
ports are in the same group and no traffic isolation between any two ports. If there are new
port-based VLAN groups created, the VLAN No. 1 will contain no members. The group No. 1
is a read-only VLAN group. And there are only 2 situations for this VLAN – all ports are
member ports, and all ports are not member ports.

2.6 802.1Q VLAN
IEEE 802.1q (tag-based) VLAN can add or strip the 802.1q tag depending on the requirements of the
individual transmitting port. Click the 802.1Q VLAN menu to activate the following pages to do the
configurations.
VLAN ID 1 is the default 802.1Q VLAN. VLAN ID 1 cannot be deleted. However, the VLAN ID 1
group member can be changed.
Incorrect 802.1Q VLAN settings will cause the web access to fail to connect. You can use the CLI
(Command Line Interface) to recover. The detailed CLI operating guide will be discussed in section
2.14.
Here is a simple way to recover the web access to the switch.
1. In CLI, type VE to disable 802.1Q VLAN
2. Go to 802.1Q VLAN web interface. Set the default VLAN ID 1 group member(01-24) to U
3. Go back to CLI mode, type VV to set Admin PVID (port no.=25) to 1.
4. In CLI mode, type VE to enable 802.1Q VLAN. You can access the web in the 802.1Q VLAN
enable environment now.
Currently this system supports up to 32 tag-based VLAN groups for manual entry. The following
pages will describe in detail how to do these configurations.

2.7 Trunk
This 24G web smart switch supports MAC-based trunking, which allows more than one port to be
grouped together as a single link connection between two switch devices. This is also useful for
switch-to-server and switch-to-router applications. The 24G web smart switch allows four trunk
groups that can accommodate up to eight trunk members. A port in one trunk group cannot be a
member of another trunk simultaneously. This feature provides redundancy and increases the
effective bandwidth through a link. The traffic patterns can be more balanced between the ports
within a trunk group by dynamically performing the MAC-based algorithm. It is supported only on
point-to-point links with MACs operating in full duplex mode. All links in the same trunk group
must operate at the same rate.
The 24G web smart switch provides dynamic failover when trunking is enabled. If a port in the trunk
group fails, the other ports of the trunk group assume traffic designated automatically for the trunk.
The links within the trunk group should have an equal amount of traffic. To achieve this, the switch
performs load balancing based on a distribution algorithm.
The following parameters are required to be set:
„
Distribution Criterion – chooses the distribution algorithm with which the switch performs
load balancing based on:
¾
¾
¾
SA (Source MAC Address)
DA (Destination MAC Address)
SA + DA (both SA and DA)
„
Member – the member port(s) of trunk group(s)
Select the Trunk menu on the web page to activate the page shown as below.
25

Because a trunk port can be aggregated by the member ports with the same configurations in most
functions for each other, there are some rules to limit the configurations of the trunking. The
following section will list the related rules for this function.
26
Download from Www.Somanuals.com. All Manuals Search And Download.
2.7.1 Trunking Rules
The following rules will limit the configurations for port trunking:
„
The attributes of all trunk member ports in Port Configuration, Mirror, Rate Control, 802.1Q
VLAN and Port-Based VLAN functions must be the same.
„
„
All trunk member ports can not be a capture port or monitored port in Mirror function.
If Port1/Port2 using the fibre media wants to be grouped with the ports using pure copper
(Port3 – Port24) as a trunk port, the auto negotiation option must be set to Enable for all
member ports. If both Port1 & Port2 are the only trunk member ports and they are using fibre
media, the auto negotiation option can be Enable or Disable.
„
After enabling a trunk group, a new trunk port will be created in the port list. For example,
Port2, Port4, and Port6 belong to Trunk 1. Check the other page (Port Status) with port list,
Trk1 port will be added after all normal ports. The member ports of this trunk group will
disappear.

„
When the enabled trunk group is set to disabled, all trunk member ports will be released to
ordinary ports and their functions can be configured individually. At that moment, their
configuration attributes will be retained to the last settings while they were member ports of the
trunk group. The following 3 figures show how the port configurations (e.g. Port6) will be
retained before and after the trunk (e.g. Trk1) is disabled.

2.9 QOS (Quality of Service)
The 24G web smart switch provides up to four internal transmit queues per port to support four
different traffic priorities. The high-priority traffic experiences less delay in the switch than that of
lower priority traffic under congested conditions. The 24G web smart switch provides three types of
QOS. It can assign the packet to one of four transmit queues according to 802.1P QOS. If the
incoming packet is untagged, the 24G web smart switch uses the priority field in the per-port
Default Priority in the Port Config page to assign the packet to one of four transmit queues. If the
incoming packet is tagged or priority tagged, the 24G web smart switch uses the priority field in the
incoming packet tag to assign the packet to one of four transmit queues.
The 24G web smart switch also provides a remap function. This switch always inserts the packet into
the Tx Queue by priority ID. Users can assign the map between priority and queues. This switch
handles the packets transmit by the Tx Queue Weight Setting when the Weighted Round-Robin
algorithm is selected.
Select the QOS menu on the web page to activate the page shown as below.
