CHAPTER 1
Getting to Know Your Switch
1.1 Introduction
This chapter introduces the main features and applications of the Switch. The GS1200 Series consists of
the following models:
• GS1200-5
• GS1200-5HP v2
• GS1200-8
• GS1200-8HP v2
The Switch has 5/8 ports. You can easily connect different devices, such as computers, network storage
devices, IP cameras, print servers to your home network.
The PoE ports of the GS1200-5HP v2 and GS1200-8HP v2 support IEEE802.3at High Power over Ethernet
(PoE) and IEEE802.3af PoE standard, to provide power to IP CAM, wall mounted AP, and other devices
that may be far from a power outlet.
For an advanced user, the Switch also provides a utility like web configurator to give you an easy
configuration for VLAN, QoS, basis system management, and firmware upgrade. The Switch is compliant
with IEEE802.3az (Energy Efficient Ethernet Standard), and provides power-saving benefits without
compromising performance.
Key feature differences between Switch models are as follows. Other features are common to all
models.

1.2 Applications
This section shows a few examples of using the Switch in various network environments.
1.2.1 Bridging Application
In this example the Switch connects different company departments (RD and Sales) to the corporate
backbone. It can alleviate bandwidth contention and eliminate server and network bottlenecks. All
users that need high bandwidth can connect to high-speed department servers via the Switch.
Figure 1 Bridging Application
1.2.2 VLAN Application Example
A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical
networks. Stations on a logical network belong to one or more groups. With VLAN, a station cannot
directly talk to or hear from stations that are not in the same group(s) unless such traffic first goes through
a router.
1.2.2.1 Tag-based VLAN Example
Ports in the same VLAN group share the same frame broadcast domain, thus increasing network
performance by reducing broadcast traffic. VLAN groups can be modified at any time by adding,
moving or changing ports without any re-cabling.

Shared resources such as a server can be used by all ports in the same VLAN as the server. In the
following figure only ports that need access to the server need to be part of VLAN1. Ports can belong to
other VLAN groups too.
Figure 2 Shared Server Using VLAN Example
1.3 Ways to Manage the Switch
Use any of the following methods to manage the Switch.
• Web Configurator. This allows easy Switch setup and management using a (supported) web browser.
See Chapter 4 on page 1.
1.4 Good Habits for Managing the Switch
Do the following things regularly to make the Switch more secure and to manage the Switch more
effectively.
• Change the password. Use a password that’s not easy to guess and that consists of different types of
characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an earlier working
configuration may be useful if the device becomes unstable or even crashes. If you forget your
password, you will have to reset the Switch to its factory default settings. If you backed up an earlier
configuration file, you would not have to totally re-configure the Switch. You could simply restore your
last configuration.

CHAPTER 2
Initial Setup Example
2.1 Overview
This chapter shows how to set up the Switch for an example network.
The following lists the configuration steps for the initial setup:
•Creating a VLAN
•Setting Port VID
•Power over Ethernet (PoE) Configuration
2.1.1 Creating a VLAN
VLANs confine broadcast frames to the VLAN group in which the port(s) belongs. You can create a
VLAN group with fixed port members to do this.
In this example, you want to configure port 1 as a member of VLAN 2.
Figure 5 Initial Setup Network Example: VLAN
1Click VLAN in the navigation panel and click the Create New VLAN button.
Chapter 2 Initial Setup Example
GS1200 Series User’s Guide
22
2Enter 2 in the VLAN ID field for the VLAN2 network.
3Since the VLAN2 network is connected to port 1 on the Switch, configure port 1 to be a permanent
member of the VLAN. To ensure that VLAN-unaware devices (such as computers and hubs) can receive
frames properly, set the port’s box color to green to set the Switch to remove VLAN tags before sending.
4Change the box color of other ports to gray.
5Click Apply to save the settings.
Chapter 2 Initial Setup Example
GS1200 Series User’s Guide
23
2.1.2 Setting Port VID
Use PVID to add a tag to incoming untagged frames received on that port so that the frames are
forwarded to the VLAN group that the tag defines.
In the example network, configure 2 as the port VID on port 1 so that any untagged frames received on
that port get sent to VLAN 2.
Figure 6 Initial Setup Network Example: Port VID
1Click VLAN in the navigation panel.
2Enter 2 in the PVID field for port 2 and click Apply to save your changes back to the Switch.

2.1.3 Power over Ethernet (PoE) Configuration
This example is for GS1200-5HP v2 and GS1200-8HP v2.
See Figure 21 on page 5 for an example of using PoE to power devices.
Before connecting devices that require PoE to the PoE ports, PD (Powered Devices), you must enable
PoE on those ports.
1Click Port in the navigation panel.
2Go to Port Setting, select Enable or Disable for ports that will supply power to PDs in the PoE field, and
click Apply to save your changes back to the Switch.
3After connecting the PDs to the PoE ports, you can go to the System screen to check the amount of
power the PDs are consuming (PoE Status), the maximum power the Switch can provide (PoE Total
Power), and so on.
See Section 6.2 on page 1 for more information about PoE .
Note: The total power the Switch can supply is 60W, and it’s shown in the PoE Total Power field.
The maximum power a PoE port can supply is 30W.
Note: The Switch allocates power to PDs in the order that they were connected.
Note: When the total power requested by the PDs exceeds the total PoE power budget on
the Switch, the last PD connected to the Switch won’t be powered up.

2.1 Overview
This chapter introduces and shows you how to configure the broadcast storm control feature and use
loop prevention or loop detection to prevent loops in your network. In addition, you can configure
transmission speed, flow control, and PoE on a port.
2.1.1 What You Need to Know
Read this section to know more about Loop Detection, Loop Prevention, broadcast storm control, and
PoE.
2.1.1.1 Loop Detection and Loop Prevention
A switch loop happens if there is more than one connection between two ports on the same switch or
between 2 switches connected together. If this happens, broadcasts are continually rebroadcast and
could flood the network. You must break the loop by stopping multiple paths between two switch ports.
Figure 2 Our Switch Has Two Ports Connected with Same Cable
Figure 3 Connected Switch Has Two Ports Connected with Same Cable
Figure 4 Two Connections between Switches without Spanning Tree Protocol (STP)
Loop Detection allows the Switch to discover a loop if it happens, and create a log. Loop Prevention
allows the Switch to shut down a port automatically if it discover a loop on that port. See Section 3.3 on
page 4 for more information about LEDs.

2.1.1.2 Broadcast Storm Control
Broadcast storm control limits the number of broadcast packets the Switch receives per second on the
ports. When the maximum number of allowable broadcast packets is reached per second, the
subsequent packets are discarded. Enable this feature to reduce broadcast packets in your network.
You can specify limits on each port.
2.1.1.3 PoE (GS1200-5HP v2 & GS1200-8HP v2)
The Switch supports both the IEEE 802.3af Power over Ethernet (PoE) and IEEE 802.3at High Power over
Ethernet (PoE) standards. A PoE-enabled switch is a Power Sourcing Equipment (PSE), because it
provides a source of power via its Ethernet ports. A powered device (PD) is a device such as an access
point, IP phone, or IP camera, that receives PoE (Power over Ethernet) power from a PSE through its
Ethernet port.
In the figure below, the IP camera and IP phone are PDs getting their power directly from the Switch PSE.
Aside from minimizing the need for cables and wires, PoE removes the hassle of trying to find a nearby
electric outlet to power up devices.

Flow Control A concentration of traffic on a port decreases port bandwidth and overflows buffer memory
causing packet discards and frame losses. Flow Control is used to regulate transmission of
signals to match the bandwidth of the receiving port.
The Switch uses IEEE802.3x flow control in full duplex mode and backpressure flow control in half
duplex mode.
IEEE802.3x flow control is used in full duplex mode to send a pause signal to the sending port,
causing it to temporarily stop sending signals when the receiving port memory buffers fill.
Back Pressure flow control is typically used in half duplex mode to send a “collision” signal to
the sending port (mimicking a state of packet collision) causing the sending port to temporarily
stop sending signals and resend later. Select the check box to enable it.

VLAN
3.1 Overview
This chapter shows you how to configure VLAN settings.
3.1.1 What You Need to Know
Read this section to know more about VLAN and how to configure the screens.
3.1.1.1 IEEE 802.1Q Tagged VLANs
A tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identify the VLAN membership of a
frame across bridges - they are not confined to the switch on which they were created. The VLANs can
be created statically by hand or dynamically through GVRP. The VLAN ID associates a frame with a
specific VLAN and provides the information that switches need to process the frame across the network.
A tagged frame is four bytes longer than an untagged frame and contains two bytes of TPID (Tag
Protocol Identifier, residing within the type/length field of the Ethernet frame) and two bytes of TCI (Tag
Control Information, starts after the source address field of the Ethernet frame).
The CFI (Canonical Format Indicator) is a single-bit flag, always set to zero for Ethernet switches. If a
frame received at an Ethernet port has a CFI set to 1, then that frame should not be forwarded as it is to
an untagged port. The remaining twelve bits define the VLAN ID, giving a possible maximum number of
4,096 VLANs. Note that user priority and VLAN ID are independent of each other. A frame with VID
(VLAN Identifier) of null (0) is called a priority frame, meaning that only the priority level is significant and
the default VID of the ingress port is given as the VID of the frame. Of the 4096 possible VIDs, a VID of 0 is
used to identify priority frames and value 4095 (FFF) is reserved, so the maximum possible VLAN
configurations are 4,094.
Forwarding Tagged and Untagged Frames
Each port on the Switch is capable of passing tagged or untagged frames. To forward a frame from an
802.1Q VLAN-aware switch to an 802.1Q VLAN-unaware switch, the Switch first decides where to
forward the frame and then strips off the VLAN tag. To forward a frame from an 802.1Q VLAN-unaware
switch to an 802.1Q VLAN-aware switch, the Switch first decides where to forward the frame, and then
inserts a VLAN tag reflecting the ingress port's default VID. The default PVID is VLAN 1 for all ports, but this
can be changed.
A broadcast frame (or a multicast frame for a multicast group that is known by the system) is duplicated
only on ports that are members of the VID (except the ingress port itself), thus confining the broadcast to
a specific domain.

Link Aggregation
4.1 Overview
This chapter shows you how to logically aggregate physical links to form one logical and higher
bandwidth link.
Link aggregation is the grouping of physical ports into one logical higher-capacity link. You may want to
trunk ports if for example, it is cheaper to use multiple lower-speed links than to under-utilize a high-
speed, but more costly, single-port link.

CHAPTER 6
QoS
6.1 Overview
This chapter introduces the configuration and functions of the QoS (Quality of Service) screen.
The QoS (Quality of Service) feature allows you to prioritize the flow of data passing through the Switch.
Occasionally, data might be delayed, depending on the volume of traffic and the capacity of the
equipment. Numeric and text data are usually not affected by delays, because they are reassembled
at the destination. However, when VoIP and streaming videos are reassembled, they might have some
troublesome gaps. Without QoS, all traffic data is equally likely to be dropped when the network is
congested. This can cause a reduction in network performance and make the network inadequate for
time-critical applications such as VOD (Video on Demand).
You can enable QoS to have the Switch assign each packet a priority and then queues the packet
accordingly. Packets assigned a high priority are processed more quickly than those with low priority if
there is congestion, allowing time-sensitive applications to flow more smoothly. Time-sensitive
applications include both those that require a low level of latency (delay) and a low level of jitter
(variations in delay) such as Voice over IP (VoIP) or Internet gaming, and those for which jitter alone is a
problem such as Internet radio or streaming video.
6.2 What You Need to Know
The Switch can put packets into the queues according to the port on which the packet is received or
the priority tag in the packet.
6.2.1 Port-Based QoS
The Port-Based QoS feature assigns priority to data transmitted through a particular port. When the data
arrives to a port it begins a queue. Therefore the Switch has a queue for each port. If data arrives at the
same time to all ports, ports with higher priority will be first to transmit the data received. The higher the
priority of the port, the less delays the data passing through will have.
6.2.2 IEEE 802.1p QoS
IEEE 802.1p defines a 3-bit field called PCP (Priority Code Point) within the IEEE 802.1Q VLAN tag, which is
also referred to as a CoS (Class of Service) value and indicates the frame priority level. IEEE 802.1p QoS
uses the priority value (from 0 to 7) to define up to eight traffic types. That is, each priority level defines a
Chapter 6 QoS
GS1200 Series User’s Guide
42
class of service. The table below shows the IEEE recommendations for traffic types, these may vary or be
reassigned.
Note: Frames without an explicit priority tag are treated as system traffic and assigned to
Queue0.
6.2.3 Weighted Round Robin Scheduling (WRR)
Round Robin Scheduling services queues on a rotating basis and is activated only when a port has more
traffic than it can handle. A queue is a given amount of bandwidth irrespective of the incoming traffic
on that port. This queue then moves to the back of the list. The next queue is given an equal amount of
bandwidth, and then moves to the end of the list; and so on, depending on the number of queues
being used. This works in a looping fashion until a queue is empty.
Weighted Round Robin Scheduling (WRR) uses the same algorithm as round robin scheduling, but
services queues based on their priority and queue weight (the number you select in the queue Weight
field) rather than a fixed amount of bandwidth. WRR is activated only when a port has more traffic than
it can handle. The bandwidth is divided across the different traffic queues according to their weights.
Queues with larger weights get more service than queues with smaller weights. This queueing
mechanism is highly efficient in that it divides any available bandwidth across the different traffic
queues and returns to queues that have not yet emptied.

1Choose which ports will carry the sensitive data, using the priority queuing levels given. Click on each
port’s radio button to assign a priority queue.
2Assign the weight (the number you select in the queue Weight field) to each priority. Remember the
weight is based on WRR Scheduling, explained in Section 11.2.3 on page 16. Bandwidth is divided across
the different traffic queues according to their weights. Queues with larger weights get more service than
queues with smaller weights.

assigned. Lets recap, Port-Based QoS assigns priority queuing by port, whereas IEEE 802.1P QoS assigns
queuing by PCP priority tags.
The Switch’s default settings for IEEE 802.1P QoS are shown in the next figure. The numbers from 0 to 7
refer to the priority tags for each traffic type. Refer to Table 9 on page 16.

CHAPTER 7
IGMP Snooping
7.1 Overview
This chapter shows you how to configure various multicast features.
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender to 1 recipient) or
Broadcast (1 sender to everybody on the network). Multicast delivers IP packets to just a group of hosts
on the network.
IGMP (Internet Group Management Protocol) is a network-layer protocol used to establish membership
in a multicast group - it is not used to carry user data. Refer to RFC 1112, RFC 2236 and RFC 3376 for
information on IGMP versions 1, 2 and 3 respectively.
Note: You must enable IGMP snooping to use the IPTV service.
The following table introduces the IGMP snooping default settings of the Switch.
IGMP Snooping
The Switch can passively snoop on IGMP packets transferred between IP multicast routers/switches and
IP multicast hosts to learn the IP multicast group membership. It checks IGMP packets passing through it,
picks out the group registration information, and configures multicasting accordingly. IGMP snooping
allows the Switch to learn multicast groups without you having to manually configure them.
The Switch forwards multicast traffic destined for multicast groups (that it has learned from IGMP
snooping or that you have manually configured) to ports that are members of that group. IGMP
snooping generates no additional network traffic, allowing you to significantly reduce multicast traffic
passing through your Switch.

8.1.1.1 IEEE 802.3az Energy Efficient Ethernet (EEE)
If EEE is enabled, both sides of a link support EEE and there is no traffic, the port enters Low Power Idle
(LPI) mode. LPI mode turns off some functions of the physical layer (becomes quiet) to save power.
Periodically the port transmits a REFRESH signal to allow the link partner to keep the link alive. When there
is traffic to be sent, a WAKE signal is sent to the link partner to return the link to active mode.

to a failure at upgrading firmware.
During the firmware upgrade process:
• The Switch loses power.
• The computer from which you uploaded the firmware file to the Switch is turned off.
• The Ethernet cable connecting the Switch and the computer comes loose. It’s the computer from
which you uploaded the firmware file to the Switch.
When one of the situations above happens, and you’re directed to the Firmware Upgrade screen,
follow the steps below:
1Make sure the power supply is sufficient in your environment.
2Make sure your computer’s Ethernet cable is securely connected to the Switch.
3Select the firmware file that you tried to upload to the Switch before you upgrade firmware again in the
Firmware Upgrade screen.
4Wait for the firmware upgrade process to complete. After a successful upload, the system will reboot,
and you’ll need to log into the Switch again.
