User Guide 31 Part 3 Switching CHAPTERS 1. Switching 2. Configuring Ports 3. Configuring IGMP Snooping 4. Configuring LAG 5. Configuration Example Switching 1 Switching 1.1 Overview Switching With the Switching function, you can configure port setting, IGMP Snooping and LAG. 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 User Guide 33 Switching Switching 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. Figure 1-1 IGMP Snooping Multicast packets transmission with IGMP Snooping Multicast packets transmission without IGMP Snooping Multicast router Multicast router Source Source Layer 2 switch Layer 2 switch Host A Receiver Host B Host C Receiver Host A Receiver Host B Host C Receiver Multicast packets 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. User Guide 34 Switching 2 Configuring Ports Configuring Ports Choose the menu Switching > Port Setting to load the following page. Figure 2-1 Configuring Ports Follow these steps to configure the port parameters. 1) Select the desired ports and set basic parameters for the ports. Status Enable or disable the port. With this option enabled, the port forwards packets normally. Otherwise, the port does not forward packets. By default, it is enabled. Speed/Duplex Config: Select the appropriate speed and duplex mode for the port. When Auto is selected, the port automatically negotiates speed mode with the connected device. The default setting is Auto. It is recommended to select Auto if both ends of the link support auto-negotiation. Actual: Displays the actual working state of the port. Flow Control Config: Select On or Off to enable or disable the Flow Control feature. When Flow Control is enabled, when the switch get overloaded, it will send a PAUSE frame to notify the peer device to stop sending data for a specific period of time, thus avoiding the packet loss caused by congestion. By default, it is Off. Actual: Displays the current state of the Flow Control function of the port. LAG Displays the LAG which the port belongs to. 2) Click Apply. User Guide 35 Switching Configuring Ports Note: • It is recommended to set the ports on both ends of a link with the same speed and duplex mode. • Keep the port that is connected to the management device enabled, or you cannot access the switch. • The parameters of the port members in a LAG should be set as the same.

Configuring Port Based VLAN 4. Configuring 802.1Q VLAN 5. Configuration Example for 802.1Q VLAN Configuring VLAN 1 Overview 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. User Guide 51 Configuring VLAN Overview 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.

Configuring Storm Control 5. Configuration Example for Basic QoS Configuring QoS 1 QoS 1.1 Overview QoS 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 to certain types of traffic. 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. User Guide 65 Configuring QoS 2 Configuring Basic QoS 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 In this mode, the switch prioritizes packets according to their ingress ports, regardless of the packet field or type. The port based QoS mode supports four priority queues, which are labeled as 1, 2, 3, and 4. 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. 802.1P determines the priority of packets based on the PRI value. In this mode, the switch only prioritizes packets with VLAN tag, regardless of the IP header of the packets. DSCP Based DSCP (Differentiated Services Code Point) 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 (bit 0-bit 5) of the DS field is used to represent DSCP priority. The DSCP values are from 0 to 63. In this mode, the switch only prioritizes IP packets. Note: The switch works in one and only one QoS mode at any time. When a specific QoS mode is enabled, the other two QoS modes will be disabled automatically.

Configuring PoE Configuring PoE 1 Overview Overview Note： Only TL-SG1016PE supports the PoE configuration. 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.
