TL-SG2109WEB/TL-SL2210WEB/TL-SL2218WEB/TL-SL2428WEB/TL-SL2452WEB Gigabit Web Smart Switch User's Guide
SFP module support hot-plugging, plug the SFP module into the SFP port and the switch can identify it automatically.
3.3 Note
¾¾ The surface on which the switch is placed should be adequately secured to prevent it from becoming unstable and/or falling over.
¾¾ Ensure the power source circuits are properly grounded.
¾¾ Ensure the power cable, extension cable, and/or plug is not damaged. ¾¾ Ensure the switch is not exposed to water.
¾¾ Ensure the switch is not exposed to radiators and/or heat sources.
¾¾ Do not push foreign objects into the switch, as it may cause a fire or electric shock.
¾¾ Allow the switch to cool before removing covers or touching internal equipment.
¾¾ Use the switch only with approved equipment. If the switch is connected to other network devices with UTP cable, ensure that the cable is not more than 100 meters .

Chapter 4: Function Description
This section presents the network concepts referred in switch function description.
4.1 System Setting
System setting contains the following topics: displaying and configuring the switch information, upgrading firmware, backing up and loading configuration, rebooting and soft-resetting, configuring username and password.
4.1.1 System Information
The system information contains hardware version, software version, system description, system name, system location, contact information and run time.
4.1.2 File Transfer
TL-SG2109WEB/TL-SL2210WEB/TL-SL2218WEB/TL-SL2428WEB/TL- SL2452WEB Gigabit Web Smart Switch is equipped with the function of configuration backup, configuration loading and system upgrading.
The configuration file and executive file are transferred in TFTP protocol.
TFTP (Trivial File Transfer Protocol) is dedicated to transferring files between two network stations. It’s based on UDP protocol.
4.1.3 Reboot & Reset
The “Reset” indicates “Soft-reset” here. Soft-resetting restores the switch configuration to default except the switch IP address.

TL-SG2109WEB/TL-SL2210WEB/TL-SL2218WEB/TL-SL2428WEB/TL-SL2452WEB Gigabit Web Smart Switch User's Guide
4.1.4 User
The username and password can be modified in order to exclude illegal users.
4.2 Port Setting
4.2.1 Port Parameter
4.2.1.1 Duplex Mode
Ports have the duplex modes: 10M HD, 10M FD, 100M HD, 100M FD and 1000M FD (Giga port support).
The First part indicates the transmission rate and the second part indicates the duplex mode.
¾¾ HD: half-duplex, the port supports transmission between the device and the client in only one direction at a time.
¾¾ FD: full-duplex, the port supports transmission between the device and its link partner in both directions simultaneously.
Switch support auto negotiation is a protocol between two link partners that enables a port to advertise its transmission rate and duplex mode to its partner.
4.2.1.2 Flow Control
Flow control enables lower speed devices to communicate with higher speed devices. This is implemented by the higher speed device refraining from sending packets.
4.2.1.3 Port Security
13
TL-SG2109WEB/TL-SL2210WEB/TL-SL2218WEB/TL-SL2428WEB/TL-SL2452WEB Gigabit Web Smart Switch User's Guide
If the port security is enabled, it will not learn new MAC address and only transmit the frames from the MAC address list in the port’s static MAC address table.
4.2.2 Port Statistic and Port Status
Port Statistic calculates the statistics of each port, such as how many frames, error frames, broadcast frames it has received, and so on.
Port Status indicates whether the port is linked, not linked or disabled, what speed and duplex mode it is working on, and whether flow control is enabled or disabled.
4.2.3 Storm Control
Storm control limits the amount of multicast, broadcast and UL (the address hasn't been learned) frames accepted and forwarded by the device. When
Layer 2 frames are forwarded, broadcast, multicast and UL frames are flooded to all ports on the relevant VLAN. This occupies bandwidth, and loads all nodes on all ports.
A Storm is a result of an excessive amount of these frames simultaneously transmitted across a network by a single port. Forwarded message responses are heaped onto the network, straining network resources or causing the network to time out. Storm control is enabled for all ports by defining the packet type and the rate at which the packets are transmitted. The system measures the incoming defined frame rates on each port, and discards the frames when the rate exceeds a user-defined rate.

4.2.4 Port Description
Use a description word to indicate the port.
4.3 Network Setting
The network module provides the function of setting switch IP address, dynamic binding and aging time, configuring static MAC address and filtering
MAC address, displaying dynamic bound address and ping.
4.3.1 Switch IP Address
An IP address is indispensable for a switch to be accessed. TheTL- SG2109WEB/TL-SL2210WEB/TL-SL2218WEB/TL-SL2428WEB/TL-
SL2452WEB Gigabit Web Smart Switch provides the configuration interface of IP address, netmask and default gateway.
DHCP (Dynamic Host Configuration Protocol) is dedicated for the DHCP client to obtain IP configuration information from the DHCP server. Two types of information are included in IP configuration information. One type is specific configuration information; another is IP address parameter. DHCP is based on client-server mode. The network station that offers the IP configuration information is called DHCP server.
Make sure that a DHCP server is correctly connected to the network, enable the DHCP client function of the switch, then the switch will automatically obtain IP address, netmask and default gateway from the DHCP server.
If more than one DHCP servers are available in the network, the switch will choose one according to a specific algorithm.
15
TL-SG2109WEB/TL-SL2210WEB/TL-SL2218WEB/TL-SL2428WEB/TL-SL2452WEB Gigabit Web Smart Switch User's Guide
Notice:
If no DHCP server is present in the network, the DHCP client fails to get IP configuration information, the switch then restores the IP parameters to default in several minutes to ensure a valid IP address being equipped.
4.3.2 Aging Time and Dynamic Address Table
A dynamic MAC address table is maintained inside the switch. A MAC address is the physical address of a network device; it is six-bytes long and should be hole in a subnet.Anetwork device can be identified by its MAC address.
A dynamic address table entry contains two items: MAC address and its corresponding switch port. The dynamic address table is volatile. The dynamic address entry begins to age once it has been added; it will be purged if it isn’t renewed in a specified length of time, which is defined as aging time.
The aging time ranges from 0 to 3825 seconds for this switch family.
The default value is 300 seconds. Dynamic address table entry won’t age if 0 is set. The aging time precision is 15 seconds.
4.3.3 Static MAC Address Table
A static MAC address table entry contains a MAC address and its corresponding switch port. All the packets taking that MAC address as their destination will be forwarded to the corresponding switch port.
The static MAC address won’t age, which differs from the dynamic MAC address. The static MAC address table entry is always valid before it is deleted.
