1.1 Product Overview

Easy Smart Switch is an ideal upgrade from Unmanaged Switch, designed for Small Office and Home Office networks. The switch supports the following features:

● Traffic monitoring: Port mirroring, loop prevention and cable test enable the administrator to monitor traffic of the network effectively.

● VLAN: MTU VLAN, Port based VLAN and 802.1Q VLAN can restrict broadcast domain, enhance network security and help manage devices easily.

● QoS: Port based QoS, 802.1P based QoS and DSCP/802.1P based QoS optimize traffic on your business network, and keep latency-sensitive traffic moving smoothly. Bandwidth control helps distribute and utilize network bandwidth reasonably. Storm control helps avoid network broadcast storm.

● PoE: PoE (Power over Ethernet) is a remote power supply function. With this function, the switch can supply power to the connected devices over twisted-pair cables.

 Note: 
The PoE Config is only available on TL-SG1016PE, TL-SG1218MPE and TL-SG1428PE. For TL-SG108PE, TL-SG105PE and TL-SG1210MPE, this feature is not supported.

1.2 Logging Into the Switch

To configure your switch through a web browser on your PC, follow these steps:
1) Connect your switch to the network and connect your PC to the switch.
2) Find out the IP address of the switch.

● By default, the switch receives an IP address from a DHCP server (or a router that functions as a DHCP server) in your network. You can find out this IP address on the DHCP server.

● If the switch cannot receive an IP address from a DHCP server, it uses the static IP address of 192.168.0.1, with a subnet mask of 255.255.255.0.

3) Configure IP address on your PC to make sure the switch and PC are in the same subnet.

● If the switch uses an IP address assigned by a DHCP server, set your PC to obtain an IP address automatically from the DHCP server.

● If the switch uses the static IP address of 192.168.0.1, configure your PC’s IP address as 192.168.0.x (”x” ranges from 2 to 254), and subnet mask as 255.255.255.0.

4) Launch a web browser on your PC. The supported web browsers include, but are not limited to, the following types:

● IE 8.0, 9.0, 10.0, 11.0

● Firefox 26.0, 27.0

● Chrome 32.0, 33.0

5) In the address bar of the web browser, enter the IP address of the switch. Here we suppose the switch uses the static IP address 192.168.0.1.

6) Enter the username and password in the pop-up login window. Before proceeding with further configuration, you need to set up username and password by following the prompts on the page (if prompted to log in before setting username and password, use admin for both the username and password).

 Note:
The first time you log in, change the password to better protect your network and devices.

3.1.1 Overview

With the switching feature, you can configure port setting, IGMP Snooping and LAG.

3.1.2 Supported Features

The switch supports the following features about switching:
Port Setting
You can configure port status, speed, duplex mode and flow control for ports. 
IGMP Snooping
In a point-to-multipoint network, packets can be sent in three ways: unicast, broadcast and multicast. With unicast, many copies of the same information will be sent to all the receivers, occupying a large bandwidth.
With broadcast, information will be sent to all users in the network no matter they need it or not, wasting network resources and impacting information security.
Multicast, however, solves all the problems caused by unicast and broadcast. With multicast, the source only needs to send one piece of information, and all and only the users who need the information will receive copies of the information. In a point‑to‑multipoint network, multicast technology not only transmits data with high efficiency, but also saves a large bandwidth and reduces network load.
When IGMP Snooping is disabled on the switch, multicast packets will be broadcast in the Layer 2 network; when IGMP Snooping is enabled on the switch, multicast data from a known multicast group will be transmitted to the designated receivers instead of being broadcast in the Layer2 network. The following figure shows how IGMP snooping works.

LAG
With LAG (Link Aggregation Group) function, you can aggregate multiple physical ports into a logical interface to increase link bandwidth and enhance the connection reliability.

5.1 Overview

VLAN (Virtual Local Area Network) is a network technique that solves broadcasting issues in local area networks. It is usually applied in the following occasions:

■ To restrict broadcast domain: VLAN technique divides a big local area network into several VLANs, and all VLAN traffic remains within its VLAN. It reduces the influence of broadcast traffic in Layer 2 network to the whole network.

■ To enhance network security: Devices from different VLANs cannot achieve Layer 2 communication, and thus users can group and isolate devices to enhance network security.

■ For easier management: VLANs group devices logically instead of physically, so devices in the same VLAN need not be located in the same place. It eases the management of devices in the same work group but located in different places.

There are 3 types of VLAN modes supported on the switch:

■ MTU VLAN

MTU VLAN (Multi-Tenant Unit VLAN) defines an uplink port which will build up several VLANs with each of the other ports. Each VLAN contains two ports, the uplink port and one of the other ports in the switch, so the device connected to the uplink port can communicate with the device connected to any other port, but devices connected to other ports cannot communicate with each other.

■ Port Based VLAN

VLANs are divided based on ports. In port based VLAN mode, each port can only be added to one VLAN.

■ 802.1Q VLAN

The IEEE 802.1Q protocol defines a new format of VLAN data frame (Tagged Frame). As the following figure shows, compared to the traditional Ethernet data frame (Untagged Frame), the VLAN data frame (Tagged Frame) adds a VLAN tag.

On receiving a tagged frame, the switch checks the VID (VLAN ID) contained in the VLAN tag to determine which VLAN the frame belongs to. On receiving an untagged frame, the switch will first insert a VLAN tag to the frame, using the PVID (Port VLAN ID) of the port as its VID, and then forward it as a tagged frame.

 Note: 

● The switch works in one and only one VLAN mode at any time. When a specific VLAN mode is enabled, the other two VLAN modes will be disabled automatically and the corresponding VLAN configuration will be lost.

● The switch supports up to 32 VLANs simultaneously.

5.2 Configuring MTU VLAN

Choose the menu VLAN > MTU VLAN to load the following page.

Follow these steps to configure MTU VLAN:

1) Select MTU VLAN configuration as Enable. Click Apply.

3) In the table below, you can verify the configuration result of port based VLAN. You can delete a VLAN as you wish by selecting the VLAN and clicking Delete.

 Note: 

● By default, all the ports are added to VLAN 1.

● Once a port is added to another VLAN, it is deleted from the original VLAN automatically.

● Once a port is removed from all the other VLANs, it is added to VLAN 1 automatically.

● VLAN 1 includes at least one port and cannot be deleted.

5.4 Configuring 802.1Q VLAN

To complete the 802.1Q configuration, follow these steps:

1) Configure the VLAN, including creating a VLAN and adding the ports to the VLAN.

2) Configure the PVID.

3) In the table below, you can verify the configuration result of 802.1Q VLAN. You can delete a VLAN as you wish by selecting the VLAN and clicking Delete.

 Note: 

● By default, all the ports are added to VLAN 1.

● The port can be removed from VLAN 1 only when the port is also a member of the other VLANs.

● Once a port is removed from all the current VLANs, it is added to VLAN 1 automatically.

● VLAN 1 cannot be deleted.

5.4.2 Configuring the PVID

Choose the menu VLAN > 802.1Q PVID Setting to load the following page.

 Note: 

● The PVID configuration will take effect only when 802.1Q VLAN mode is enabled.

● You can specify a PVID only when the corresponding VLAN exists.

5.5.1 Network Requirements

As the following figure shows, a company has two departments. Hosts of the same department are located in different places and connected to different switches respectively.

It’s required that:

■ Hosts of both departments can access the internet.

■ Hosts of the same department can communicate with each other, but hosts of different departments cannot.

5.5.2 Configuration Scheme

To implement the above requirements, configure 802.1Q VLAN on both switches.

■ Create VLAN 2. On Switch A, add port 2 and port 4 to VLAN 2, while on Switch B, add port 1, port 2 and port 4 to VLAN 2.

■ Create VLAN 3. On Switch A, add port 3 and port 4 of Switch A to VLAN 3, while on Switch B, add port 1, port 3 and port 4 to VLAN 3.

■ Configure the default VLAN 1 to make sure the router can communicate with all ports of the two switches.

Tables below show configurations of VLANs on each switch.

 Note: 

If a port is connected to terminal devices like computers, add the port to the corresponding VLANs as an untagged port, because terminal devices typically do not support VLAN tags.

5.5.3 Configuration Steps

6.1.1 Overview

With network scale expanding and applications developing, internet traffic is dramatically increased, thus resulting in network congestion, packet drops and long transmission delay. Typically, networks treat all traffic equally on FIFO (First In First Out) delivery basis, but nowadays many special applications like VoD, video conferences, VoIP, etc. require more bandwidth or shorter transmission delay to guarantee the performance.

With QoS (Quality of Service) technology, you can classify and prioritize network traffic to provide differentiated services for certain types of traffic.

6.1.2 Supported Features

With the QoS feature, You can configure QoS Basic, Bandwidth Control and Storm Control on the switch to maximize the network performance and bandwidth utilization.

QoS Basic

The switch classifies the ingress packets, maps the packets to different priority queues and then forwards the packets to implement QoS function.

Bandwidth Control

Bandwidth Control functions to control the ingress traffic rate and egress traffic rate on each port via configuring the available bandwidth of each port. In this way, the network bandwidth can be reasonably distributed and utilized.

Storm Control

Storm Control function allows the switch to monitor broadcast packets, multicast packets and UL-frames (Unknown unicast frames) in the network. If the transmission rate of the packets exceeds the limit, the packets will be automatically discarded to avoid network broadcast storm.

6.2 Configuring Basic QoS

Configuration Guidelines

Select the QoS mode according to your network requirements. Three QoS modes are supported on the switch: Port Based, 802.1P Based and DSCP Based.

■ Port Based

The port based QoS mode supports four priority queues, which are labeled as 1 (Lowest), 2 (Normal), 3 (Medium) and 4 (Highest).

In this mode, the switch prioritizes packets according to their ingress ports, regardless of the packet field or type.

■ 802.1P Based

802.1P defines the first three bits in 802.1Q Tag as PRI field. The PRI values are from 0 to 7. The tagged packets are mapped to 4 priority levels based on the PRI value (Lowest=0, 1; Normal=2, 3; Medium=4, 5; Highest=6, 7).

In this mode, the switch only prioritizes packets with VLAN tag, regardless of the IP header of the packets.

■ DSCP/802.1P Based

DSCP priority determines the priority of packets based on the ToS (Type of Service) field in their IP header. RFC2474 re-defines the ToS field in the IP packet header as DS field. The first six bits of the DS field is used to represent DSCP priority. The DSCP values are from 0 to 63. The IP packets are mapped to 4 priority levels based on the DSCP value (Lowest=0-15; Normal=16-31; Medium=32-47; Highest=48-63).

In this mode, the switch prioritizes packets with IP header based on DSCP priority first. Then, the switch prioritizes packets with VLAN tag but without IP header base on the PRI field. Finally, the switch prioritizes packets without VLAN tag or IP header based on port priority.

6.2.1 Configuring QoS in Port Based Mode

 Note: 

● For a port, the storm control feature and the ingress rate control feature cannot be enabled at the same time. If you enable storm control for a port, ingress rate control will be disabled for that port automatically.

● For ports in the same LAG, storm control should be configured the same to ensure a successful port aggregation.

6.5.1 Network Requirements

As shown below, both RD department and Marketing department can access the internet. When congestion occurs, the traffic from two departments can both be forwarded and the traffic from the Marketing department should take precedence.

6.5.2 Configuration Scheme

To implement this requirement, you can configure QoS in port based mode to put the packets from the Marketing department into the queue with the higher priority than the packets from the RD department. Follow these procedures to configure QoS in port based mode.

1) Enable port based mode.

2) Map port 1 and port 2 to different priorities queues.

Demonstrated with TL-SG1016PE, the following section provides configuration steps.

6.5.3 Configuration Steps

1)Choose the menu QoS > QoS Basic to load the following page. In the Global Config section, select QoS mode as Port Based. Click Apply.

2) In the Port Based Priority Setting section, specify the priority queue for port 1 as 1 (Lowest) and click Apply. Specify the priority queue for port 2 as 4 (Highest) and click Apply.

7.1 Overview

 Note: 

● The PoE Config is only available on TL-SG1016PE, TL-SG1218MPE and TL-SG1428PE. For TL-SG108PE, TL-SG105PE and TL-SG1210MPE, this feature is not supported.

PoE (Power over Ethernet) is a remote power supply function. With this function, the switch can supply power to the connected devices over twisted-pair cables.

Some devices such as IP phones, access points (APs) and cameras may be located far away from the AC power source in actual use. PoE can provide power for these devices without requiring to deploy power cables. This allows a single cable to provide both data connection and electric power for the device.

■ PSE

Power sourcing equipment (PSE) is a device that provides power for PDs on the Ethernet, for example, the PoE switch. PSE can detect the PDs and determine the device power requirements.

■ PD

Powered device (PD) is a device receiving power from the PSE, for example, IP phones and access points. According to whether PDs comply with IEEE standard, they can be classified into standard PDs and non-standard PDs. Only standard PDs can be powered via TP-Link PoE switches.

7.2 Configuring PoE

Choose the menu PoE > PoE config to load the following page.

Follow these steps to configure PoE:

1) In the Global Config section, you can view the current PoE parameters. You can configure the System Power Limit. Click Apply.

2) In the Port Config section, select the ports you want to configure and specify the parameters. Click Apply.

7.3 Configuring PoE Auto Recovery

With PoE Auto Recovery enabled, the switch detects the link status between the ports and connected PDs. The switch pings the IP addresses of PDs constantly. If a PD loses connection, the switch will reboot it automatically.

Choose the menu PoE > PoE Auto Recovery to load the following page.

Follow these steps to enable PoE Auto Recovery and configure the parameters:

1) In the Global Config section, enable or disable PoE Auto Recovery. Click Apply.

 Note: 

● Before upgrading the connected PoE powered device (PD), disable PoE Auto Recovery on the corresponding port to avoid PD’s damage.

● It is recommended to configure the switch and its connected PDs to the same subnet, and when 802.1Q VLAN enabled, the connected PD should be in the port’s default VLAN (whose ID is the PVID). For detailed configurations, refer to Configuring 802.1Q VLAN.

2) In the Port Config section, select the desired ports and specify the parameters. Click Apply.
