    Note: The Port Security function is disabled for the LAG port member. Only the port is removed from the LAG, will the Port Security function be available for the port. 5.1.4 Port Isolation Port Isolation provides a method of restricting traffic flow to improve the network security by forbidding the port to forward packets to the ports that are not on its forward portlist.

  • Page 35: Lag

    5.2 LAG LAG (Link Aggregation Group) is to combine a number of ports together to make a single high-bandwidth data path, so as to implement the traffic load sharing among the member ports in the group and to enhance the connection reliability. For the member ports in an aggregation group, their basic configuration must be the same.

  • Page 42: Static Address

    5.4.2 Static Address The static address table maintains the static address entries which can be added or removed manually, independent of the aging time. In the stable networks, the static MAC address entries can facilitate the switch to reduce broadcast packets and remarkably enhance the efficiency of packets forwarding without learning the address.

Aging Time: Enter the Aging Time for the dynamic address. Search Option Search Option: Select a Search Option from the pull-down list and click the Search button to find your desired entry in the Dynamic Address Table.

  • Page 45: Filtering Address

    Tips: Setting aging time properly helps implement effective MAC address aging. The aging time that is too long or too short results decreases the performance of the switch. If the aging time is too long, excessive invalid MAC address entries maintained by the switch may fill up the MAC address table. This prevents the MAC address table from updating with network changes in time.

VLAN ID: Displays the corresponding VLAN ID. Port: Here the symbol “__” indicates no specified port. Type: Displays the Type of the MAC address.

  • Page 47: Chapter 6 Vlan

    Chapter 6 VLAN The traditional Ethernet is a data network communication technology based on CSMA/CD (Carrier Sense Multiple Access/Collision Detect) via shared communication medium. Through the traditional Ethernet, the overfull hosts in LAN will result in serious collision, flooding broadcasts, poor performance or even breakdown of the Internet.

  • Page 48: Q Vlan

    6.1 802.1Q VLAN VLAN tags in the packets are necessary for the switch to identify packets 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 packet only, so you can add the VLAN tag field into the data link layer encapsulation for identification.
  • Page 49 （3） GENERAL: The GENERAL port can be added in multiple VLANs and set various egress rules according to the different VLANs. The default egress rule is UNTAG. The PVID can be set as the VID number of any VLAN the port belongs to. PVID PVID (Port Vlan ID) is the default VID of the port.

  • Page 56: Chapter 7 Spanning Tree

    Chapter 7 Spanning Tree STP (Spanning Tree Protocol), subject to IEEE 802.1D standard, is to disbranch a ring network in the Data Link layer in a local network. Devices running STP discover loops in the network and block ports by exchanging information, in that way, a ring network can be disbranched to form a tree-topological ring-free network to prevent packets from being duplicated and forwarded endlessly in the network.
  • Page 57 Figure 7-1 Basic STP diagram STP Timers Hello Time: Hello Time ranges from 1 to 10 seconds. It specifies the interval to send BPDU packets. It is used to test the links. Max. Age: Max. Age ranges from 6 to 40 seconds. It specifies the maximum time the switch can wait without receiving a BPDU before attempting to reconfigure.
  • Page 58 Comparing BPDUs Each switch sends out configuration BPDUs and receives a configuration BPDU on one of its ports from another switch. The following table shows the comparing operations. Step Operation If the priority of the BPDU received on the port is lower than that of the BPDU if of the port itself, the switch discards the BPDU and does not change the BPDU of the port.
  • Page 59 RSTP (Rapid Spanning Tree Protocol), evolved from the 802.1D STP standard, enable Ethernet ports to transit their states rapidly. The premises for the port in the RSTP to transit its state rapidly are as follows. The condition for the root port to transit its port state rapidly: The old root port of the switch stops forwarding data and the designated port of the upstream switch begins to forward data.
  • Page 60 Figure 7-2 Basic MSTP diagram MSTP MSTP divides a network into several MST regions. The CST is generated between these MST regions, and multiple spanning trees can be generated in each MST region. Each spanning tree is called an instance. As well as STP, MSTP uses BPDUs to generate spanning tree. The only difference is that the BPDU for MSTP carries the MSTP configuration information on the switches.

  • Page 76: Chapter 8 Multicast

    Chapter 8 Multicast Multicast Overview In the network, packets are sent in three modes: unicast, broadcast and multicast. In unicast, the source server sends separate copy information to each receiver. When a large number of users require this information, the server must send many pieces of information with the same content to the users.
  • Page 77 Multicast Address 1. Multicast IP Address: As specified by IANA (Internet Assigned Numbers Authority), Class D IP addresses are used as destination addresses of multicast 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.

  • Page 78: Igmp Snooping

    IGMP Snooping In the network, the hosts apply to the near router for joining (leaving) a multicast group by sending IGMP (Internet Group Management Protocol) messages. When the up-stream device forwards down the multicast data, the switch is responsible for sending them to the hosts. IGMP Snooping is a multicast control mechanism, which can be used on the switch for dynamic registration of the multicast group.

  • Page 79: Snooping Config

    3. IGMP Leave Message The host, running IGMPv1, does not send IGMP leave message when leaving a multicast group, as a result, the switch can not get the leave information of the host momentarily. However, after leaving the multicast group, the host does not send IGMP report message any more, so the switch will remove the port from the corresponding multicast address table when its member port time times out.

    Chapter 9 QoS QoS (Quality of Service) functions to provide different quality of service for various network applications and requirements and optimize the bandwidth resource distribution so as to provide a network service experience of a better quality. This switch classifies the ingress packets, maps the packets to different priority queues and then forwards the packets according to specified scheduling algorithms to implement QoS function.
  • Page 94 2. 802.1P Priority Figure 9-2 802.1Q frame As shown in the figure above, each 802.1Q Tag has 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 determines the priority of the packets based on the Pri value.
  • Page 95 Figure 9-4 SP-Mode WRR-Mode: Weight Round Robin Mode. In this mode, packets 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. WRR queue overcomes the disadvantage of SP queue that the packets in the queues with lower priority can not get service for a long time.

    The QoS module is mainly for traffic control and priority configuration, including two submenus: DiffServ and Bandwidth Control. 9.1 DiffServ This switch classifies the ingress packets, maps the packets to different priority queues and then forwards the packets according to specified scheduling algorithms to implement QoS function. This switch implements three priority modes based on port, on 802.1P and on DSCP, and supports four queue scheduling algorithms.
