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.
GS1200 Series User’s Guide
10
Chapter 1 Getting to Know Your Switch
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 16.

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.

Initial Setup Example

5.1 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
5.1.1 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.
CHAPTER 5
In this example, you want to configure port 1 as a member of VLAN 2.
Figure 15 Initial Setup Network Example: VLAN
1 Click VLAN in the navigation panel and click the Create New VLAN button.
GS1200 Series User’s Guide
21
Chapter 5 Initial Setup Example
2 Enter 2 in the VLAN ID field for the VLAN2 network.
3 Since 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.
4 Change the box color of other ports to gray.
5 Click Apply to save the settings.
GS1200 Series User’s Guide
22
5.1.2 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 16 Initial Setup Network Example: Port VID
Chapter 5 Initial Setup Example
1 Click VLAN in the navigation panel.
2 Enter 2 in the PVID field for port 2 and click Apply to save your changes back to the Switch.
GS1200 Series User’s Guide
23
Chapter 5 Initial Setup Example
5.1.3 Power over Ethernet (PoE) Configuration
This example is for GS1200-5HP v2 and GS1200-8HP v2.
See Figure 21 on page 31 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.
1 Click Port in the navigation panel.
2 Go 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.
3 After 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 27 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.

7.1.1.2 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.
7.1.1.3 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.

8.1 Overview

This chapter shows you how to configure VLAN settings.
8.1.1 What You Need to Know
Read this section to know more about VLAN and how to configure the screens.
8.1.1.1 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).
CHAPTER 8

VLAN

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.

User Priority
3 Bits
CFI

VLAN ID

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

9.1 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 high­speed, but more costly, single-port link.

Link Aggregation Algorithm
Select the outgoing traffic distribution type. Packets from the same source and/or to the same destination are sent over the same link within the trunk. By default, the Switch uses the MAC SA & DA distribution type. If the Switch is behind a router, the packet’s destination or source MAC address will be changed. In this case, set the Switch to distribute traffic based on its IP address to make sure port trunking can work properly.
Select MAC SA to distribute traffic based on the packet’s source MAC address. Select MAC DA to distribute traffic based on the packet’s destination MAC address. Select MAC SA & DA to distribute traffic based on a combination of the packet’s source and
destination MAC addresses.
Link Aggregation Group
The field identifies the default link aggregation group(s) the Switch supports.
Note: By default, the GS1200-5 and GS1200-5HP v2 have a link aggregation group
containing ports 3 and 4.
Note: By default, the GS1200-8 and GS1200-8HP v2 have two link aggregation
groups. One contains ports 3 and 4, and the other contains ports 7 and 8.
Note: Make sure the ports in a link aggregation group must have the same PVID and

11.1 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.
CHAPTER 11
QoS

11.2 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.
11.2.1 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.
11.2.2 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
GS1200 Series User’s Guide

Chapter 11 QoS
class of service. The table below shows the IEEE recommendations for traffic types, these may vary or be reassigned.
Table 9 IEEE Priority to Traffic Type Mapping Recommendations
PCP PRIORITY ACRONYM TRAFFIC TYPES
1 0 (lowest) BK Background 0 1 (default) BE Best Effort 2 2 EE Excellent Effort 3 3 CA Critical Applications 4 4 VI Video, <100 ms latency and jitter 5 5 VO Voice, <10 ms latency and jitter 6 6 IC Internetwork Control 7 7 (highest) NC Network Control
Note: Frames without an explicit priority tag are treated as system traffic and assigned to
Queue0.
11.2.3 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.

Chapter 11 QoS

11.3 Port-Based QoS Screen

The Switch’s default settings for Port-Based QoS are shown in the next figure.
Figure 28 QoS > Port-Based QoS
The Switch allows four priority levels, shown in the table below.
Table 10 Priority Queuing Levels in QoS
QUEUE NAME PRIORITY LEVEL
Queue 0 Low Priority Queue 1 Normal Priority Queue 2 Medium Priority Queue 3 High Priority
To apply Port-Based QoS to the Switch, follow these steps:
1 Choose 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.
2 Assign 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 42. Bandwidth is divided across the different traffic queues according to their weights. Queues with larger weights get more service than queues with smaller weights.
3 Click the Apply button after you are finished assigning priorities to the ports.

11.4 IEEE 802.1P QoS Screen

Both Port-Based QoS and IEEE 802.1P QoS use the same priority queuing levels, shown in Table 10 on
page 43. Remember the difference amongst both features relies on how the priority queuing is
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 42.
Figure 29 QoS > IEEE 802.1P QoS
To apply IEEE 802.1P QoS to the Switch, follow these steps:
1 Choose which priority tags will carry the sensitive data, using the priority queuing levels given. Click on
each priority tag’s radio button to assign a priority queue.
2 Assign 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 42. Bandwidth is divided across the different traffic queues according to their weights. Queues with larger weights get more service than queues with smaller weights.

12.1 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.

13.1.1.1 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.
