Chapter 6 VLAN The traditional Ethernet is a data network comm unication technology basi ng on CSMA/CD (Ca rrier 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 packet s of different 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-VLA N-tagged packet, it will add a VLAN tag to the packet according to the PVID of its rece ived port and forward the packet s.
T o ensure the normal communication of the factory sw itch, the default VLAN of all ports is set to VLAN1. The following entries are displayed on this screen: VLAN T able VLAN ID Select ： Click the Select button t o quick-select the corresponding entry based on the VLAN ID number you entered.

Port St ates In an MSTP , ports can be in the following four states: Forwarding: In this status the port can rece ive/forward data, receive/send BPDU p acket s as well as learn MAC address. Learning: In this status the port can rece ive/send BPDU p ackets and learn MAC address.
Figure 7-4 STP Config The following 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 p anning T ree Protocol.
Note: 1. The forward delay parameter and the network dia meter are correlated. A t oo small forward delay parameter may result in temporary loops. A too large forward delay may cause a network unable to resume the normal state in time. The default value is recommended.
Figure 7-5 STP Summary 7.2 Port Config On this page you can c onfigure the parameters of th e ports for CIST . Choose the menu Sp anning T ree → Port Config to load the following page.

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.
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. The multicast IP addresses range from 224.0.0.0~239.255.255.255. The following table displays the range and description of several special multicast IP addresses.
IGMP Snooping In the network, the hosts apply to the near router for joining (leavin g) a multicast group by sending IGMP (Internet Group Management Protocol) me ssages. When the up-str eam device forwards down the multicast data, the switch is responsible for sending them to the host s.
3. IGMP Leave Message The host, running IGMPv1, does not send IGMP l eave message when leaving a multicast group, as a result, the switch can not get the leave information of the host momentarily .
Figure 8-4 Basic Config The following entries are displayed on this screen: Global Config IGMP Snooping: Select Enable/Disable IGMP S nooping function globally on the switch. Unknown Multicast: Select the operation for the swit ch to process unknown multicast, Forward or Discard.

if the port can not be added to the mul ticast group, the switch will drop the IGMP report message. In that way , the multicast streams will not be trans mitted to this port, which allows you to control hosts joining the multicast group. 8.4.1 IP-Range On this page you can figure the desired IP-ranges to be filtered.

Query Packet: Displays the number of query packets the port received. Report Packet (V1): Displays the number of IGMPv1 report packets the port received.
Chapter 9 QoS QoS (Quality of Service) functi ons to provide different quality of service for various network applications and requirements and optim ize the bandwidth resource dist ribution so as to provide a network service experience of a better quality .
2. 802.1 P Priority Figure 9-2 802.1Q frame As shown in the figure above, each 802.1Q T ag ha s a Pri field, comprising 3 bits. The 3-bit priority field is 802.1p priority in the range of 0 to 7. 802.1P priority determi nes the priority of the packet s based on the Pri value.
Figure 9-4 SP-Mode 2. WRR-Mode: Weight Round Robin Mode. In this mode, packe ts in all the queues are sent in order based on the weight value for each queue and every queue can be assured of a certain service time. The weight value indicates the occupied proportion of the resource.
9.1 DiffServ This switch classifies the ingr ess packets, map s the p ackets to dif ferent priority queues and then fo rwar ds th e pac ke ts ac cor din g to sp eci fi ed scheduli ng algorithms to implement QoS function. This switch implem ents three priority modes based on port, on 802 .
Configuration Procedure: Ste p Operation Description 1 Select the port priority Required. On QoS → DiffServ → Port Priority page, configure the port priority . 2 Configure the mapping relation between the CoS priority and TC Required. On QoS → DiffServ → 802.
9.1.3 802.1P/CoS Mapping On this page you can configu re the mapping rel ation between t he 802.1P priority tag-id/C oS-id and the TC-id. 802.1P gives the Pri fi eld in 802. 1Q tag a recommen ded definitio n. This field, rangin g from 0-7, is used to divid e packets into 8 priorities.
Configuration Procedure: Ste p Operation Description 1 Configure the mapping relation between the 802.1P priority T ag/CoS and the TC Required. On QoS → DiffServ → 802.1P/CoS mapping page, configure the mappi ng relation between the 802.1P priority T ag/CoS and the TC.
