In this guide, the term “Switch” (first letter upper case) refers to your
ENMGS-16+2, and “switch” (first letter lower case) refers to other
Ethernet switches.

1

INTRODUCTION

This chapter describes the features of the ENMGS-16+2 and some
background information about Ethernet/Fast Ethernet/Gigabit Ethernet
switching technology.

Gigabit Ethernet Technology

Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the
same packet structure, format, and support for CSMA/CD protocol,
full duplex, flow control, and management objects, but with a tenfold
increase in theoretical throughput over 100-Mbps Fast Ethernet and a
hundredfold increase over 10-Mbps Ethernet. Since it is compatible
with all 10-Mbps and 100-Mbps Ethernet environments, Gigabit
Ethernet provides a straightforward upgrade without wasting a
company’s existing investment in hardware, software, and trained
personnel.

The increased speed and extra bandwidth offered by Gigabit Ethernet
is essential to coping with the network bottlenecks that frequently
develop as computers and their busses get faster and more users use
applications that generate more traffic. Upgrading key components,
such as your backbone and servers to Gigabit Ethernet can greatly
improve network response times as well as significantly speed up the
traffic between your subnets.

Gigabit Ethernet enables fast optical fiber connections to support
video conferencing, complex imaging, and similar data-intensive
applications. Likewise, since data transfers occur 10 times faster than
Fast Ethernet, servers outfitted with Gigabit Ethernet NIC’s are able to
perform 10 times the number of operations in the same amount of
time.

3

In addition, the phenomenal bandwidth delivered by Gigabit Ethernet
is the most cost-effective method to take advantage of today and
tomorrow’s rapidly improving switching and routing internetworking
technologies. And with expected advances in the coming years in
silicon technology and digital signal processing that will enable
Gigabit Ethernet to eventually operate over unshielded twisted-pair
(UTP) cabling, outfitting your network with a powerful 1000-Mbps­capable backbone/server connection creates a flexible foundation for
the next generation of network technology products.

Fast Ethernet Technology

The growing importance of LANs and the increasing complexity of
desktop computing applications are fueling the need for high
performance networks. A number of high-speed LAN technologies
have been proposed to provide greater bandwidth and improve
client/server response times. Among them, 100BASE-T (Fast
Ethernet) provides a non-disruptive, smooth evolution from the
current 10BASE-T technology. The non-disruptive and smooth
evolution nature, and the dominating potential market base, virtually
guarantees cost-effective and high performance Fast Ethernet
solutions.

100Mbps Fast Ethernet is a standard specified by the IEEE 802.3
LAN committee. It is an extension of the 10Mbps Ethernet standard
with the ability to transmit and receive data at 100Mbps, while
maintaining the CSMA/CD Ethernet protocol. Since the 100Mbps
Fast Ethernet is compatible with all other 10Mbps Ethernet
environments, it provides a straightforward upgrade and takes
advantage of the existing investment in hardware, software, and
personnel training.

4

Switching Technology

Another approach to pushing beyond the limits of Ethernet technology
is the development of switching technology. A switch bridges
Ethernet packets at the MAC address level of the Ethernet protocol
transmitting among connected Ethernet or Fast Ethernet LAN
segments.

Switching is a cost-effective way of increasing the total network
capacity available to users on a local area network. A switch
increases capacity and decreases network loading by dividing a local
area network into different segments, which don’t compete with each
other for network transmission capacity.

The switch acts as a high-speed selective bridge between the
individual segments. The switch, without interfering with any other
segments, automatically forwards traffic that needs to go from one
segment to another. By doing this the total network capacity is
multiplied, while still maintaining the same network cabling and
adapter cards.

Switching LAN technology is a marked improvement over the
previous generation of network bridges, which were characterized by
higher latencies. Routers have also been used to segment local area
networks, but the cost of a router, the setup and maintenance required
make routers relatively impractical. Today switches are an ideal
solution to most kinds of local area network congestion problems.

5

VLAN (Virtual Local Area Network)

A VLAN is a group of end-stations that are not constrained by their
physical location and can communicate as if a common broadcast
domain, a LAN. The primary utility of using VLAN is to reduce
latency and need for routers, using faster switching instead. Other
VLAN utility includes:

Security, Security is increased with the reduction of opportunity in
eavesdropping on a broadcast network because data will be switched
to only those confidential users within the VLAN.

Cost Reduction, VLAN’s can be used to create multiple broadcast
domains, thus eliminating the need of expensive routers.

Installation

The site where you install the hub stack may greatly affect its
performance. When installing, consider the following pointers:

Install the Switch in a fairly cool and dry place. See Technical
Specifications for the acceptable temperature and humidity operating
ranges.

Install the Switch in a site free from strong electromagnetic field
generators (such as motors), vibration, dust, and direct exposure to
sunlight.

9

Leave at least 10cm of space at the front and rear of the hub for
ventilation.

Install the Switch on a sturdy, level surface that can support its weight,
or in an EIA standard-size equipment rack. For information on rack
installation, see the next section, Rack Mounting.

When installing the Switch on a level surface, attach the rubber feet to
the bottom of each device. The rubber feet cushion the hub and
protect the hub case from scratching.

11

Connecting Network Cable

The Switch supports 1000Mbps Gigabit Ethernet that runs in Auto­negotiation mode and 10Mbps Ethernet or 100Mbps Fast Ethernet that
runs both in half and full duplex mode and 1000Mbps Gigabit
Ethernet runs in full duplex mode using four pairs of Category 5
cable.

These 1000BASE-T ports are Auto-MDI type port. The Switch can
auto transform to MDI-II or MDI-X type, so you can just make an
easy connection that without worrying if you are using a standard or
crossover twisted-pair cable.

There are additional 2 ports combo mini-GBIC slot for optional mini­GBIC module.

has a Web GUI interface for smart switch configuration. The Switch
can be configured through the Web Browser. A network administrator
can manage, control and monitor the switch from the local LAN. This
section indicates how to configure the Switch to enable its smart
functions

Login

Before you configure this device, note that when the ENMGS-16+2
Switch is configured through an Ethernet connection, make sure the
manager PC must be set on same the IP network. For example, when
the default network address of the default IP address of the Web Smart
Switch is 192.168.1.1, then the manager PC should be set at

192.168.1.x (where x is a number between 2 and 254), and the default
subnet mask is 255.255.255.0.

Open Internet Explorer 5.0 or above Web b rowser.
Enter IP address

Speed:

28

The 1000BASE-T connections can operate in Forced Mode settings
(1000M Full, 100M Full, 100M Half, 10M Full, 10M Half), Auto, or
Disable. The default setting for all ports are Auto. The mini-GBIC
(Gigabit Fiber) connections can operate in Forced Mode settings
(1000M Full), Auto, or Disable

Flow Control:

This setting determines whether or not the Switch will be handling
flow control. Set Flow Control to Enable for avoiding data transfer
overflow. Or it sets to Disable; there is either no flow control or other
hardware/software management.

When the port is set to forced mode, then the flow control will
automatically set to Disable.

QoS:

Displays each port’s 802.1p QoS priority level for received data
packet handling. Default setting for all ports is Middle. You can
change the priority settings in 802.1p Default Priority.

29

IEEE 802.1Q VLAN

A VLAN is a group of ports that can be anywhere in the network, but
communicate as though they were in the same area.

VLANs can be easily organized to reflect department groups (such as
R&D, Marketing), usage groups (such as e-mail), or multicast groups
(multimedia applications such as video conferencing), and therefore
help to simplify network management by allowing users to move
devices to a new VLAN without having to change any physical
connections.

IEEE802.1Q VLAN function base on VID and PVID to distributes
different VLAN groups. But IEEE802.1Q VLAN doesn't support
multi-need server application via Untag port (Untag Port cannot
overlap in different VLAN groups). For multi-need server application
via Untag Port that the device support IEEE802.1Q Asymmetric
VLAN function can be covered it.

Here is an example of two VLAN groups with several ports on each
group and VLAN 1 (VID 01) does not have communication with
VLAN 2 (VID 02).

Example1:

Figure 26. Untag VLAN setting example

Step1: Set VLAN1 member port 9~16 to “Not Member”, then apply setting.
Step2: Create VID 2 and set port 9~16 to “Untag Port” member, then apply setting.

35

802.1Q Asymmetric VLAN settings exampl e:
Port 1~16 in VLAN 1, port1~5 in VLAN 2, port1,6~9 in VLAN

3. All VLAN1~3 have access to Inte rnet via port 1.

Note: The multi-need server must be support IEEE 802.1Q VLAN

Example2:

Figure 27. Asymmetric VLAN setting example

Step1: Enable Asymmetric VLAN function.
Step2: Add VID2 and set port 1~5 to “Untag Port” member, then apply setting.
Step3: Add VID3 and set port1 and Port 6~9 to “Untag Port” member, then apply

setting.
Step4: Set PVID Port 2~9 PVID value to below list:

Figure 28. Asymmetric VLAN’s PVID setting example

Tag VLAN Setting

The IEEE802.1Q protocol defines a new format of the frame; it adds a
tag header in the original Ethernet frame, as follows:

IEEE802.1Q Tag VLAN is divided by VLAN ID (VID). On receiving
a frame, the switch checks the VID in the tag header of the frame to
decide which VLAN it belongs to. If the receiving frame doesn’t
contain the tag header, the switch will assign a tag to the frame, using
the PVID of the port as its VID.

Figure 29. Tag VLAN

37

Example3:

Figure 30. Tag VLAN setting example

Step1: Set VLAN1 member port1 to “Tag Port” and port 9~16 to “Not Member”, then
apply setting.

Step2: Add VID2 and set port1 to “Tag Port” and Port 9~16 to “Untag Port” member,
then apply setting.

Note: The multi-need server must be support IEEE 802.1Q VLAN, the sever uplink
port is port1.

38

Another example is about setting tag VLAN with two switches.
Switch 1’s VLAN 1 (2 ~ 3 ports) have access to the Switch 2’s VLAN
1 (2 ~ 3 ports).

Example4:

Figure 31. Tag VLAN setting example

The settings of VLAN group for two devices are same.
Step1: Set Switch1’s VLAN1 member port 1and 4~15 to “Not Member”, then apply

setting.
Step2: Set Switch2’s VLAN1 member as Switch1.
Step3: Uplink two switches via Port 16.

39

Trunk Setting

The Trunking function enables the cascading of two or more ports for
a combined larger bandwidth. Up to six Trunk groups may be created,
each supporting up to 8 ports. Add a Trunking Name and select the
ports to be trunked together, and click Apply to activate the selected
Trunking groups.

Figure 32. Trunk Configuration

Be sure that the selected trunk setting port must connect to the device
with a same VLAN group.

40

Mirror Setting

Port Mirroring is a method of monitoring network traffic that forwards
a copy of each incoming and/or outgoing packet from one port of the
Switch to another port where the packet can be studied. This enables
network managers to better monitor network performances.

Figure 33. Mirror Setting

Selection of the Sniffer mode is as follow:
TX (transmit) mode: this mode will duplicate the data transmit from

the source port and forward to the Sniffer port.
RX (receive) mode: this mode will duplicate the data that send to the

source and forward to the Sniffer port.
Both (transmit and receive) mode: this mode will duplicate both the

data transmit from and data that send to the source port, then it will
forward to the Sniffer port.

41

IEEE 802.1p Default Priority

This feature displays the status Quality of Service priority levels of
each port, and for packets that are untagged, the switch will assign the
priority in the tag depending on your configuration.

Figure 34. IEEE 802.1p Default Priority Setting

42

Broadcast Storm Control Setting

The Broadcast Storm Control feature provides the ability to control
the receive rate of broadcasted packets. If Enabled (default is
Disabled), threshold settings of 8,000 ~ 4,096,000 bytes per second
can be assigned. Press Apply for the settings to take effect.

Figure 35. Broadcast Storm Control Setting

Jumbo Frame Setting

Jumbo Frames enable the transportation of identical data in fewer
frames. This ensures less overhead, lower processing time, and fewer
interruptions. Maximum packet length supported is 10240 bytes.

System Setting

Find that there are nine items, including System Information, System

Setting, Trap Setting, Password Setting, Statistics, Factory Reset,
Backup Setting, Firmware Upload and System Reboot in System

menu.

System Information

Press on the “System Information” to present the system information
status on this screen, it will show the Product Name, Firmware
Version, Protocol Version, MAC Address, System Name, Location
Name, IP Address, Subnet Mask, Default Gateway, Trap IP, Login
Timeout and System Up Time.

System Setting

The System Setting includes IP Information and System information.
There are two ways for the switch to attain IP: Static and DHCP
(Dynamic Host Configuration Protocol).

When using static mode, the IP Address, Subnet Mask and Gateway
can be manually configured. When using DHCP mode, the Switch will
first look for a DHCP server to provide it with an IP address, network
mask, and default gateway before using the default or previously
entered settings. By default the IP setting is static mode.

By entering a System Name and System Location, the device can
more easily be recognized through the Web Manageme nt Utility and
in other Web-Smart devices on the LAN. The Login Timeout controls
the idle time-out for security purposes, when there is no action in the
Web-b ased Utility. When the Login Timeout expires, the Web based
Utility requires a re-login before using the Utility again.

Trap Setting

By configuring the Trap Setting, it allows Web Management Utility to
monitor specified events on this Web-Smart Switch. By default, Trap
Setting is Disabled. When the Trap Setting is Enabled, enter the
Destination IP address of the managing PC that will receive trap
information.
