Chapter 6 VLAN The traditional Ethernet is a data network communication technology based on CSMA/CD (Carrier Sense Multiple Access/Collision Detect) vi a shared communication medium.
6.1 802.1Q VLAN VLAN tags in the packet s are necessary for the sw itch to identify packets of dif ferent VLANs. The switch works at the data link layer in OSI model and it can identify the data link layer encapsulation of the packe t only , so you can add the VLAN tag field into the data link layer encapsulation for identification.
PVID PVID (Port VLAN ID) is the default VID of the port. When the switch receives an un-VLAN-tagged packet, it will add a VLAN tag to the packet according to the PVID of its received port and forward the packet s.
Figure 6-3 VLAN T able T o ensure the normal communication of the factory sw itch, the default VLAN of all ports is set to VLAN1. The following ent ries are displaye d on this screen: VLAN Create VLAN ID ： Enter the VLAN ID you want to create. It ranges from 2 to 4094.

Configure Switch B Ste p Operation Description 1 Configure the Link T ype of the ports Required. On VLAN → 802.1Q VLAN → VLAN Config page, configure the link type of Port 7, Port 6 and Port 8 as Untagged, T agged and Untagged respectively . 2 Create VLAN10 Required.
Chapter 7 S p anning T ree STP (S panning T ree P rotocol), subject to IEEE 802 .1 D standard, is to disbranch a ring netwo rk in the Data Link layer in a local netwo rk.
Figure 7-1 Basic STP diagram STP T imers Hello T ime: Hello T ime ranges from 1 to 10 seconds. It specifie s the interval to send BPDU p ackets. It is used to test the links. Max. Age: Max. Age ranges from 6 to 40 sec onds. It specifies the maximum time the switch can wait without receiving a BPDU before attempting to reconfigure.
Comparing BPDUs Each switch sends out configur ation BPDUs and receives a confi guration BPDU on one of its ports from another switch. The following t abl e shows the comparing operations.
stop s forwarding data and the des ignated port of the up stream switch begins to forward data. The condition for the designated port to transit its port st ate rapidly: The designated port is an edge port or connecting to a point-to-point link.
Figure 7-2 Basic MSTP diagram MSTP MSTP divides a network into several MST r egions. The CST is generat ed between these MST regions, and multiple spanning trees can be gener ated in each MST region. Each spanning tree is called an instance. As well as STP , MSTP us es BPDUs to generate sp anning tree.
Figure 7-3 Port roles The S panning T ree module is mainly for spanning tree configuration of the switch, including four submenus: STP Config , Port Config , MSTP Inst ance and STP Security . 7.1 STP Config The STP Config function, for global configuration of spanning trees on the switch, can be implemented on STP Config and STP Summary p ages.
The followin g entries are displayed on this screen: Global Config STP: Select Enable/Disable STP f unction globally on the switch. V ersion: Select the desired STP version on the switch. STP: S panning T ree Protocol. RSTP: Rapid S panning Tr ee Protocol.
7.1.2 STP Summary On this page you can view the related parameters for S panning T ree function. Choose the menu S p anning T ree → STP Config → STP Summary to load the following page.
Figure 7-6 Port Config The following entries are displayed on this screen: Port Config Port Select: Click the Select button to quick-select the corresponding port based on the port number you entered. Select: Select the desired port for STP conf iguration.

Chapter 8 Multicast Multicast Overview In the network, packet s are sent in three modes: unicast, broadcas t and multicast. In unicast, the source server sends separate copy information to each receiver . When a large number of users require this information, the serv er must send many pieces of info rmation with the same content to the users.
4. Real time is highly demanded and certain packet s drop is allowed. Multicast Address 1. Multicast IP Address: As specified by IANA (Internet Assigned Numbers Authority), Class D IP addresses are used as destination addresses of multic ast packets.

Chapter 12 SNMP SNMP Overvie w SNMP (Simple Network Management Protocol) has gained the most extens ive application on the UDP/IP networks. SNMP provides a management frame to monitor and maintain the network devices. It is used for automatica lly managing the various network devices no matter the physical differences of the devices.
application requirement. SNMP v1: SNMP v1 adopts Community Name authentic ation. The community name is used to define the relation between SNMP Management S tation and SNMP Agent. The SNMP packet s failing to pass community name authentication are discarded.
The User configure d in a SNMP Group can manage the switch via the client program on management station. The specif ied User Name and the Auth/Privacy Password are used for SNMP Management S tation to access the SNMP Agent, functioning as the p assword.
12.1.2 SNM P View The OID (Object Identifier) of t he SNMP packets is used to describe the managed objects of the switch, and the MIB (Management Information Base) is the set of the OIDs. The SNMP View is created for the SNMP management station to manage MIB objects.
Figure 12-5 SNMP Group The following ent ries are displaye d on this screen: Group Config Group Name: Enter the SNMP Group name. The Group Name, Security Model and Security Level compose the identifier of the SNMP Group. The Groups with these three items the same are considered to be the same.
Notif y V iew : Select the View to be the Notify View . The management station can receive trap messages of the assigned SNMP view generate d by the switch's SNMP agent. Group T able Select: Select the desired entry to delete the corresponding group.
User Config User Name: Enter the User Name here. User T ype: Select the type for the User . Local User: Indicates that the user is connected to a local SNMP engine. Remote User: Indicates that the user is connected to a remote SNMP engine.
12.1.5 SNM P Communit y SNMP v1 and SNMP v2c adopt community name authentication. The comm unity name can limit access to the SNMP agent from SNMP network ma nagement station, functioni ng as a password. If SNMP v1 or SNMP v2c is employed, you can di rectly configure the SNMP Community on this page without configuring SNMP Group and User .
Configuration Procedure: If SNMPv3 is employed, please take the following step s: Ste p Operation Description 1 Enable SNMP function globally . Required. On the SNMP → SNMP Config → Global Config page, enable SNMP function globally . 2 Create SNMP View .
12.2 Notification With the Notification function enabl ed, the switch can initiatively report to the management station about the important events that o ccur on the V iews (e.g., the manag ed device is rebooted), which allows the management station to monitor and process the events in time.

Chapter 13 LLDP Note: Only TL-SG2424P supports LLDP function. LLDP (Link Layer Discovery Protocol) is a Layer 2 protocol that is used for network devices to advertise their own device information periodically to neighbors on the same IEEE 802 local area network.
or to allow t he port to both transmit and receive LLDPD Us. Four LLDP admin statuses are supported by each port. Tx&Rx: the port can both transmit and receive LLDPDUs. Rx_Only: the port can receive LLDPDUs only . Tx_Only: the port can transmit LLDPDUs only .
The followin g table shows the details about the currently defined TL Vs. TL V type TL V Name Description Usage in LLDPDU 0 End of LLDPDU Mark the end of the TL V sequence in LLDPDUs. Any information following an End Of LLDPDU TL V shall be ignored. Mandatory 1 Chassis ID Identifies the C hassis address of the connected device.
Note: For detailed introduction of TL V , please refer to IEEE 802.1AB standard and ANSI/TIA-1057. In TP-LINK switch, the following LL DP optional TL Vs are supported. Port Description TLV The Port Description TLV allows network management to advertise the IEEE 802 LAN station's port description.
